I am Sakshi Sharma, I have completed my post-graduation in applied physics. I like to explore in different areas and article writing is one of them. In my articles, I try to present physics in most understanding manner for the readers.
In this article, we will analyse solar energy to chemical energy conversion examples and other aspects of it.
Photosynthesis is the conversion of solar energy (light fuel from the Sun) into chemical fuel (a form of glucose or other organic molecules). It happens in the chloroplasts. Chlorophyll is a green substance found in plants.
Photosynthesis allows plants to create their own food from carbon dioxide and humidity in the existence of sunlight and chlorophyll. This procedure results in the release of oxygen and the production of glucose. Glucose can be stored, turned into starch, or utilized for respiration. Photosynthesis has been used by trees, shrubs, grasses, and algae even though time immemorial. They accomplish this by producing the organic pigment chlorophyll in their cells.
With the help of sunlight, chlorophyll-containing plant parts transform carbon dioxide (CO2) and moisture into oxygen and glucose. The plant gets its energy from glucose, and oxygen is discharged. As a result, forests are frequently termed “green lungs. Artificial photosynthesis aspires to be like its natural counterpart. In essence, this is about “merely” separating water into hydrogen and oxygen utilizing sunlight, rather than producing glucose.
The hydrogen generated can then be utilized as a fuel, for illustration, to power fuel-cell cars, or it could indeed be utilized to synthesize hydrocarbons such as methane (the primary element of organic gas), ethane, propane, or even (liquid) octane.
How to convert solar energy to chemical energy?
Light energy is converted to chemical energy. Whenever a photochemically energized special chlorophyll molecule of the photosynthetic active site gives up an electron during an oxidation reaction, light fuel is transformed into chemical fuel.
One particle of the pigment chlorophyll soaks up one photon and gives up one electron in the glow responses. This electron is gone to pheophytin, an altered form of chlorophyll that goes the electron to a quinone molecule, enabling the beginning of a stream of electrons beneath an electron transit sequence that ultimately contributes to the reduction of NADP to NADPH.
This also creates a proton slope throughout the chloroplast membrane, which ATP synthase uses for concurrent ATP synthesis. The chlorophyll molecule recovers an electron from a water molecule via a procedure known as photolysis, which results in the formation of the dioxygen (o2) molecule.
When solar energy is converted to Chemical energy?
When a photon with a wavelength less than 700nm is absorbed, the chlorophyll molecule donates a high-energy electron, that is utilized to force a hydrogen ion along a chloroplast’s thylakoid membrane. This results in the formation of a chemiosmotic potential across the membrane. Many particles engrained in this membrane perform various functions by allowing hydrogen ions to flow in the opposite direction.
The main thing that occurs here is that NADP+ is converted to NADPH. In cell-cell procedures, NADPH serves as an overall power source. NADPH is used by plants to convert CO2 into carbohydrates.
Solar energy to chemical energy conversion process
Photosynthesis occurs in chloroplasts, which are unique plant cells found in foliage. A separate chloroplast is similar to a bag filled with the essential components of photosynthesis. It contains water consumed from the plant’s roots, atmospheric carbon dioxide consumed by the leaves, and chlorophyll enclosed in thylakoids, which are folded, maze-like organelles.
Chlorophyll is the true photosynthesis catalyst. This light-sensitive molecule is required to initiate the process by cyanobacteria, plankton, and land plants.
Because chlorophyll molecules soak up green rays so poorly, they portray it like tiny reflectors, having caused our eyes to perceive most leaves as green. Only in autumn, after chloroplasts degrade, do we see the endless hues of yellow and orange generated by carotenoid pigments.
How to convert solar energy to chemical energy at home?
You’ve probably heard of PV, which is used in solar panels. Once the sun glows on a solar panel, the power is absorbed by the PV cells on the board. This power produces electrical charges that travel in response to an inbuilt electric field in the cell, causing electricity to flow.
Reflectors are used to portray and start focus entirely sunlight onto recipients, which accumulate solar fuel and transform it to steam, which can then be utilized to generate fuel or accumulate it for afterward use. It is mostly used in very large electricity plants.
Solar power innovation does not end with the era of electric power by PV or CSP systems. These photovoltaic power platforms should be incorporated into residences, businesses, and established power layouts using a variety of traditional and eco-friendly energy outlets.

Solar Water Heating is a common example of solar energy
Many people are unaware that solar water boilers and solar space boilers are expensive and better ways to steam homes without needing to deploy solar boards. Solar space heaters use an atmosphere or water medium to convert the sun’s power into heating fuel. Water, on the other hand, is used as a heat travel medium in solar water heaters. Active and passive photovoltaic heater systems are available.
Pumps are used in equipment to enable water to travel and thus generate heat. In contrast, passive systems rely on natural circulation. The capacity to heat a whole swimming pool at an incredibly low cost distinguishes thermal heating systems from other heaters such as oil and gas impellers.
Photovoltaic Cells
Solar cells are used to power a wide range of devices, from calculators to whole industries. Even though tiny cells have long been utilized to strengthen small devices such as calculators, large cells have made inroads into the industry in recent years. Large cells are powerful enough to power entire houses.
Because of their environmental friendliness, they are chilly contributors to energy. They are not only long-lasting, but require little maintenance, and are relatively inexpensive in the long run.
Solar Technology
Electronics now include features that allow for solar-powered charging. A popular explanation is a solar-powered connector, which can charge anything from tablets to cell phones. Solar-powered lamps are also available today, and they can be charged simply by being exposed to sunlight.
As more focus is placed on renewable radiation, there is no doubt that many folks will proceed to start embracing solar for ingredients that can be fueled by light from the sun. The Apple handset is an illustration of how solar fuel has been successfully used to energize an electronic gadget. Besides a traditional watch, an Apple handset does not need to be charged every day.
Lighting from the Sun
Often these property owners improve their properties’ stylistic significance and productivity by integrating exterior solar illumination. Solar lamp, with the exception of classical external illumination, does not require advanced installation but since the lamps use wireless advanced technologies and encapsulate the sun’s power throughout the day to eliminate the need for typically provided power at night.
Since solar lamps are not as common as solar panels, they are rapidly catching up to smart household heating systems and LED lamps as power goods that could indeed support reduced energy bills.
Solar Rooftop
Because of the vast array of gadgets accessible in the industry presently, most people overlook the most important use of solar energy, which is rooftop solar. Since solar authority has many applications, such as powering batteries and flying airplanes, it can also play an important role in reducing carbon imprints and energy bills. Each year, a rooftop solar system can save residents thousands of cash.
When considering switching to solar fuel, make an idea of calculating your potential solar savings and determining the impact financing in solar devices could have on your household finances.
Using small products and household enhancement gadgets to enhance the productivity of your residence is a good idea. In the long-term, nevertheless, installing a solar board is the best way to reduce your electricity bills and reduce carbon emissions.
Solar energy vs Chemical energy
Sunlight causes a chemical response that provides energy for plants to grow. Chemical energy is the electricity stashed in the bonds that exist between compounds such as subatomic particles and molecules. A chemical reaction is a process by which atoms are reconfigured as a consequence of a chemical change, likely to outcome in the formation of new material.
The moister is divided into hydrogen and oxygen using energy from the sun energy in the one technique. Daylight extraction via solar cells and moisture electrolysis are procedures that can (in theory) be conducted individually. Even so, as Andreas Borschulte describes, they could really be merged at a tiny level. In photoelectrochemical cells, also recognized as PEC cells, this is termed photo electrolysis. Empa scientists uncovered a PEC cell in 2014. Consider a moisture vessel outfitted with a photoanode and a reverse electrode. The photoanode soaks up daylight and generates electricity, which is used to divide the water.
Conclusion
Furthermore, solar lighting comes with a plethora of extravagant illumination clusters that can significantly improve the open-air looks of any estate. These lighting products are inexpensive and widely available in local retail stores. The prevalence of road lamps today is due to their low cost and ready availability.
Dew point and bubble point are fundamental concepts in thermodynamics and fluid mechanics, crucial for understanding phase transitions and the behavior of refrigeration systems. These parameters play a vital role in various industries, including HVAC, meteorology, and process engineering. In this comprehensive guide, we will delve into the technical details, formulas, and practical applications of dew point and bubble point, providing a valuable resource for physics students.
Understanding Dew Point
Dew point is the temperature at which a gas, typically water vapor, begins to condense into a liquid when the gas is cooled. At a given temperature, there is a maximum amount of water vapor that the air can hold before it reaches its dew point and condensation occurs. The dew point temperature is an essential measurement in various applications, as it helps determine the moisture content in the air and the potential for condensation formation.
The Antoine Equation and Dew Point Calculation
The relationship between dew point, temperature, and pressure is described by the Antoine equation, a semi-empirical formula used to estimate the vapor pressure of a pure component at a given temperature. The Antoine equation is expressed as:
log10(P) = A - (B / (C + T))
where:
– P is the vapor pressure (in appropriate units)
– T is the temperature in Kelvin
– A, B, and C are component-specific constants
To calculate the dew point, you can rearrange the Antoine equation to solve for the temperature T when the vapor pressure P is known, typically the saturation vapor pressure of the gas at the given conditions.
Dew Point in Refrigeration Systems
In the context of zeotropic refrigerants, the dew point occurs at a higher temperature during the condensation process compared to the bubble point during boiling. This is because the temperature difference between the refrigerant and the surrounding environment is greater during condensation than during boiling. This temperature difference drives the phase change process, with the dew point occurring at a higher temperature when the refrigerant is condensing.
Understanding Bubble Point
Bubble point, on the other hand, is the temperature at which a liquid begins to vaporize when it is heated. It is the highest temperature at which a liquid and its vapor can coexist in equilibrium. The bubble point pressure is the pressure at which the liquid begins to boil, and it is an essential measurement in the design and operation of distillation columns and other separation processes.
The Antoine Equation and Bubble Point Calculation
Similar to the dew point, the bubble point can be calculated using the Antoine equation. In this case, you would need to rearrange the equation to solve for the temperature T when the vapor pressure P is known, typically the saturation vapor pressure of the liquid at the given conditions.
Bubble Point in Refrigeration Systems
In the context of zeotropic refrigerants, the bubble point occurs at a lower temperature during the boiling process compared to the dew point during condensation. This is because the temperature difference between the refrigerant and the surrounding environment is greater during condensation than during boiling. This temperature difference drives the phase change process, with the bubble point occurring at a lower temperature when the refrigerant is boiling.
Hysteresis Effects in Nanopores
The bubble point and dew point of hydrocarbons in nanopores exhibit hysteresis effects, meaning that the bubble point and dew point curves do not overlap. This phenomenon is due to the pore structure and surface chemistry of nanopores, which can significantly affect the phase behavior of hydrocarbons.
Calculating Dew Point and Bubble Point using Aspen HYSYS
Aspen HYSYS, a widely used process simulation software, provides tools for calculating both dew point and bubble point. The Peng-Robinson equation of state or other thermodynamic models available in the software can be used to determine these important parameters.
Practical Applications and Importance
Dew point and bubble point are crucial measurements in various industries, including:
HVAC: Dew point is used to determine the moisture content in the air and the potential for condensation, which is essential for the design and operation of HVAC systems.
Meteorology: Dew point is a key parameter in weather forecasting and understanding atmospheric conditions.
Process Engineering: Bubble point and dew point are important in the design and operation of distillation columns, evaporators, and other separation processes.
Refrigeration Systems: The temperature difference between the bubble point and dew point of zeotropic refrigerants is a crucial factor in the performance and efficiency of refrigeration systems.
Conclusion
Dew point and bubble point are fundamental concepts in thermodynamics and fluid mechanics, with far-reaching applications in various industries. By understanding the technical details, formulas, and practical implications of these parameters, physics students can gain a deeper understanding of phase transitions and the behavior of complex systems. This comprehensive guide provides a valuable resource for students to explore the intricacies of dew point and bubble point, equipping them with the knowledge to tackle real-world problems and advance their studies in the field of physics.
The direction of torque is a crucial concept in physics, particularly in the study of rotational motion and equilibrium. Torque is a vector quantity, meaning it has both magnitude and direction, and understanding how to determine the direction of torque is essential for solving a wide range of problems in mechanics. In this comprehensive guide, we will delve into the details of the right-hand rule, which is the primary method used to find the direction of torque, and explore various examples and applications to solidify your understanding.
The Right-Hand Rule: Aligning Fingers and Curling to Find Torque Direction
The right-hand rule is the go-to method for determining the direction of torque. This rule involves aligning the fingers of your right hand with the first variable, such as the radius or moment arm, and then curling them in the direction of the second variable, such as the force. The direction that your thumb points is the direction of the torque vector.
Let’s consider an example to illustrate the application of the right-hand rule. Imagine a door being pushed open:
Start at the hinges of the door, which represent the pivot point.
Point the fingers of your right hand in the direction of the force, which is the push on the door.
Curl your fingers in the direction of the moment arm, which is the distance from the hinges to the point of force application.
The direction that your thumb points is the direction of the torque vector.
In this case, your thumb would point out of the page, indicating that the torque is positive.
The right-hand rule can also be applied to wheels and other rotating objects. In this scenario, you would align your fingers with the radius of the wheel and then curl them in the direction of the force. The direction that your thumb points is the direction of the torque vector.
Torque as a Vector Quantity: Magnitude and Direction
It is important to understand that torque is a vector quantity, meaning it has both a magnitude and a direction. The magnitude of torque is calculated using the formula:
τ = |r||F|sinθ
Where:
– τ is the magnitude of the torque
– |r| is the magnitude of the moment arm (the distance from the pivot point to the point of force application)
– |F| is the magnitude of the force
– θ is the angle between the force and the moment arm
The direction of the torque vector is determined using the right-hand rule, as described earlier.
Theorems and Principles Related to Torque Direction
Several theorems and principles in physics are closely related to the direction of torque. Understanding these concepts can further strengthen your understanding of how to find the direction of torque.
Principle of Moments
The principle of moments states that the sum of the moments (torques) about any point must be zero for an object to be in rotational equilibrium. This principle is crucial in determining the direction of torque and analyzing the stability of systems.
Rotational Dynamics Equations
The equations of rotational dynamics, such as the equation of angular acceleration (α = τ/I, where α is the angular acceleration, τ is the torque, and I is the moment of inertia), directly involve the direction of torque. Correctly identifying the direction of torque is essential for solving problems related to rotational motion.
Conservation of Angular Momentum
The conservation of angular momentum principle states that the total angular momentum of a closed system remains constant unless an external torque is applied. The direction of the torque determines the change in the angular momentum of the system.
Examples and Numerical Problems
To solidify your understanding of finding the direction of torque, let’s explore some examples and numerical problems.

Consider a wrench being used to tighten a nut. The force is applied perpendicular to the handle of the wrench, and the pivot point is the center of the nut.
Identify the pivot point (the center of the nut).
Point the fingers of your right hand in the direction of the force (the force applied to the wrench handle).
Curl your fingers in the direction of the moment arm (the distance from the pivot point to the point of force application).
The direction that your thumb points is the direction of the torque vector.
Example 2: Torque on a Wheel
Imagine a wheel rotating on an axle. A force is applied tangentially to the wheel’s rim.
Identify the pivot point (the center of the axle).
Point the fingers of your right hand in the direction of the force (the force applied tangentially to the wheel’s rim).
Curl your fingers in the direction of the moment arm (the radius of the wheel).
The direction that your thumb points is the direction of the torque vector.
Numerical Problem 1
A force of 10 N is applied to a door at a distance of 1 m from the hinges. Determine the direction of the torque.
Identify the pivot point (the hinges of the door).
Point the fingers of your right hand in the direction of the force (the push on the door).
Curl your fingers in the direction of the moment arm (the distance from the hinges to the point of force application).
The direction that your thumb points is the direction of the torque vector, which is positive (out of the page).
Numerical Problem 2
A force of 5 N is applied to a wheel with a radius of 0.5 m. Determine the direction of the torque.

Curl your fingers in the direction of the moment arm (the radius of the wheel).
The direction that your thumb points is the direction of the torque vector, which is positive (out of the page).

These figures provide a visual representation of the concepts discussed and can help you better understand the application of the right-hand rule in finding the direction of torque.
Conclusion
In this comprehensive guide, we have explored the essential concepts and techniques for finding the direction of torque. By understanding the right-hand rule and its application, as well as the underlying principles and theorems, you now have a solid foundation to tackle a wide range of problems involving torque and rotational motion. Remember to practice the right-hand rule with various examples and numerical problems to solidify your understanding and become proficient in determining the direction of torque.
The power necessary to open/close a bottle or similar vessel with a screwed top is known as torsion, torque pressure, or opening/closing force.
The top must be able to close the container tightly enough to prevent the contents from spilling out, but it should also be simple to open. The key to ensuring the integrity of tops and seals is to accurately replicate their releasing motion or movements and evaluate the torque forces required.
The capping torque meter is utilized as a torque management instrument on the finished item once tension limits have been specified. If torque monitoring instruments show that the topping equipment is out of tolerance, it must be corrected.
An automated torque measurement equipment is the best option for many regular tests that need accurate repeatability, human independence, and unique test protocols.
Turning a steering wheel
The impact of motor loading on the steering, which causes the driver to experience abrupt jerks on the steering while traveling, is known as steering wheel torque. The rear tires are coupled to a driving mechanism that allows operators to manoeuvre their cars.
The pressure on the navigation wheel is the consequence of the road interaction forces implemented toon the tires, as well as the dynamical configuration of the steering mechanism, and it is mainly directly proportionate to the car’s lateral acceleration, and it is conveyed proportionally to the steering axle with negligible deformations at reduced steering vantage points.
Steering wheel torque is the result of this transferred force, which is mostly attributable to engine torque on the steering, notably in front-wheel-drive cars.
See-saw
The general architecture of a seesaw, particularly the reality that it rests on the floor, ensures that the platform can never spin completely 360 degrees; however, the surface can revolve within very restricted constraints.
Imagine the clockwise rotating behaviour of a seesaw from the front, with a toddler on the left and an adolescent on the right, to demonstrate the consequences of torque.
The torque on either side must be adjusted in order for the two to be precisely balanced. Shifting mass is one option, but a movement and, as a result, this included is a more likely solution. Because the adolescent weighs precisely twice as much as the kid, the child’s this included must be precisely double as lengthy as the adolescents.
Automobiles engine
The flywheel of an engine produces torque, which is a spinning force. The higher an engine’s capacity to accomplish work, the more torque it produces. The testing is similar to work but differs somewhat. Torque is measured in pound-feet and newton meters because it is a vector (operating in one direction).
In this situation, the difference is static torque, which is the sort used to compress head bolts with a screwdriver. Static torque is generally measured in foot-pounds to prevent misunderstanding. SI, on the other hand, uses newton meters to calculate both fixed and kinetic torque.
Wrenches
A pressure wrench is a tool for tightening nuts and screws to a certain torque level. This tool enables screws to be adjusted at the correct tension, preventing harm from overtightening or parts from breaking apart due to under-tightening.
A pressure wrench is required if you want to undertake any serious repair on the motor or other mechanical parts. For example, overtightening fuel tank screws can quickly result in costly breakage and disastrous fluid loss. Catalytic plenum screws that are too tight might lead the plenum to break.
Torque standards are so important to effective automobile repair that many trade guides contain them in the back-page tables with bolt position, identification, and specific specifications, in addition to the maintenance instructions.
Projector or flexion, dial indication, button, and computerized torque wrenches are the four most common varieties, each with somewhat unique functioning concepts. The laser and scale indicators both have a basic mechanical mechanism that links to a marker that floats beyond a torque meter linked to the grip or dial indication.
The meter or dial shows the quantity of torque corresponding to the flexion of the wrench’s bent grip when pressure is imparted to it. When operating in dark all the regions, you’ll want a big pointer or meter panel if you’re purchasing a beam- or keypad kind.
Gyroscopes
A gyroscope is made up of a flywheel, which is a wheel-like disc attached to an axle, which is positioned on a bigger ring perpendicular to the wheel’s axis. The architectural solidity of the gyroscope is provided by an exterior circle in the same plane as the spinning, and the gyroscope can have multiple such concentric rings.
The spinning and axle, on the other hand, are the center of attention. The axle’s one end is usually linked to something external, whereas the opposite end is allowed to drift. Gravity has a propensity to pull the detached end of the axle lower once the flywheel starts spinning, turning it on an axis orthogonal to the flywheel’s.
The gyro may topple over as a result, but instead, it starts spinning a third axis, a horizontal axis orthogonal to both the axis of the flywheel and the direction of gravitation. As a consequence, it spins on three axes and stays extremely stable—that is, impervious to outside efforts to alter its equilibrium.
A pendulum or a parachute is applying torque when swinging
Observe the pendulum’s torque. The portion of the pendulum bob’s mass that operates throughout the curve size is the pressure that provides the restorative torque. The torque is equal to the length of the string L multiplied by the portion of the net force parallel to the arc’s radius. The torque works in the opposite direction of the angular shift, as indicated by the negative sign.
π=-L(mgsinθ)
A person riding a bicycle
While riding a bike, the peak torque that an individual can generate is roughly equivalent to 1/3 of his body weight magnified by the size of the pedal linking rod; however, if a person stays on a seat, he has three points of help and thus the torque that he may generate is roughly equivalent to 1/3 of his body weight magnified by the size of the pedal linking rod.
The highest moment that an individual can generate by transporting its center of mass as close to the pedal’s vertical plane would be approximately 1/2 of its weight increased by the size of the pedal linking rod, according to basic math.
Opening of door
Torque is intuitively understood by everyone who has actually opened a door. While opening a door, the individual pushes on the side of the door that is furthest from the joints. It takes a lot more power to push on the part nearest to the joints.
Even though the labour is the same in both circumstances (the bigger force is delivered over a shorter radius), people like to use less force, which is why the door handle is usually located in the middle.

The coefficient of static friction, denoted as μs, is a crucial parameter in understanding the behavior of objects in contact with a surface. It represents the ratio of the maximum force of friction that can be exerted before the object starts to slide, to the normal force acting on the object. Knowing the coefficient of static friction is essential in various fields, such as engineering, physics, and everyday life, as it helps predict the stability and movement of objects. In this comprehensive guide, we will delve into the details of how to find the coefficient of static friction using both theoretical and experimental methods.
Understanding the Concept of Static Friction
Static friction is the force that opposes the relative motion between two surfaces in contact with each other when they are at rest. This force arises due to the microscopic irregularities and adhesive forces between the surfaces. The coefficient of static friction, μs, is a dimensionless quantity that represents the ratio of the maximum force of static friction to the normal force acting on the object.
The formula for the coefficient of static friction is:
μs = F/N
Where:
– μs is the coefficient of static friction
– F is the maximum force of static friction
– N is the normal force acting on the object
Theoretical Approach to Finding the Coefficient of Static Friction
Calculating the Normal Force:
The normal force, N, is the force exerted perpendicular to the surface on which the object rests.
For a horizontal surface, the normal force is equal to the weight of the object: N = mg, where m is the mass of the object and g is the acceleration due to gravity.
For an inclined surface, the normal force is the component of the object’s weight perpendicular to the surface: N = mg cos(θ), where θ is the angle of inclination.
Determining the Maximum Force of Static Friction:
The maximum force of static friction, F, is the maximum force that can be applied to the object before it starts to slide.
For a horizontal surface, the maximum force of static friction is the force required to just start the object moving: F = mg sin(θ), where θ is the angle of inclination.
For an inclined surface, the maximum force of static friction is the component of the object’s weight parallel to the surface: F = mg sin(θ).
Calculating the Coefficient of Static Friction:
Once the normal force, N, and the maximum force of static friction, F, are known, the coefficient of static friction can be calculated using the formula: μs = F/N.
Experimental Approach to Finding the Coefficient of Static Friction
Tilting Method:
Place the object on a horizontal surface and gradually tilt the surface until the object just starts to slide.
The angle at which the object starts to slide, θ, is related to the coefficient of static friction by the formula: μs = tan(θ).
Pulling Method:
Place the object on a horizontal surface and attach a force gauge or spring scale to the object.
Gradually increase the force applied to the object until it just starts to slide.
The maximum force of static friction, F, is the force reading on the gauge or scale just before the object starts to slide.
The normal force, N, is the weight of the object: N = mg.
The coefficient of static friction can then be calculated using the formula: μs = F/N.
Inclined Plane Method:
Place the object on an inclined plane and gradually increase the angle of inclination until the object just starts to slide.
The angle at which the object starts to slide, θ, is related to the coefficient of static friction by the formula: μs = tan(θ).
Alternatively, you can fix the angle of the inclined plane and gradually increase the mass of the object until it just starts to slide. The coefficient of static friction can then be calculated using the formula: μs = tan(θ).

– Normal force, N = mg cos(θ) = 5 kg × 9.8 m/s^2 × cos(30°) = 43.3 N
– Force of friction, F = mg sin(θ) = 5 kg × 9.8 m/s^2 × sin(30°) = 24.5 N
– Coefficient of static friction, μs = F/N = 24.5 N / 43.3 N = 0.566

– Force of friction, F = 40 N
– Coefficient of static friction, μs = F/N = 40 N / 98 N = 0.408
Numerical Problem 2
A 3 kg block is placed on an inclined plane with an angle of 20 degrees.
The block just starts to slide when the angle is increased to 25 degrees.
Calculate the coefficient of static friction between the block and the plane.
Solution:
– Angle at which the block starts to slide, θ = 25 degrees
– Coefficient of static friction, μs = tan(θ) = tan(25°) = 0.466
Factors Affecting the Coefficient of Static Friction
The coefficient of static friction can be influenced by various factors, including:
Surface Roughness: Rougher surfaces generally have a higher coefficient of static friction compared to smoother surfaces.
Surface Materials: The materials of the contacting surfaces can significantly affect the coefficient of static friction. For example, rubber on concrete has a higher coefficient than steel on steel.
Humidity and Temperature: Changes in humidity and temperature can affect the surface properties and, consequently, the coefficient of static friction.
Contamination: The presence of contaminants, such as oil or grease, can reduce the coefficient of static friction between the surfaces.
Surface Coatings: Applying coatings or lubricants to the surfaces can alter the coefficient of static friction.

In this article, we will discuss what causes static electricity and other factors related to it.
Whenever opposite charges are not regulated, static electricity is generated. Protons and neutrons do not really move so much, while radicals love to bounce everywhere! A negative charge is assigned to an item (or person) when it contains additional electrons.
The simplest way to create static electricityis to use electricity-restricting substances termed insulators, which include rubber, cotton, and hair. Electrons make currents in electricity, which powers phones, lights, and practically all other electronics, bypassing between atoms in conductive substances such as a copper wire.
The atoms of insulators, on the other hand, do not allow electricity to move freely; instead, they acquire their title by impeding electron passage.
Whenever electrons are handed up by substances such as glass, hair, or some kinds of fabric due to friction, and those electrons accumulate voltage, the substance grows more prone to draw an electric current, which we experience as a static shock, also called an electrostatic shock.
The dryness of the winter months may be bothersome during this time of year. A shortage of moisture in your house may cause problems with wood furniture and carpeting, as well as uncomfortable health concerns. That is why it is advisable to include a humidifier that will guard against all of these issues.
What causes static electricity in the air?
Because air is an insulator, electrons cannot easily flow through it. When there is more moisture in the air, electrons may flow around moreeasily. Substances that scrape versus one other or things that are traveling apart create electric charges.
What causes static electricity in hair?
Whenever the substance of your hat scrapes against your hair strands, electrons are exchanged. As a consequence of the switch, an electric charge piles up on the hair. If there is enough moisture in the air, the charge will generally dissipate.
What causes static electricity in clothes?
Static energy in clothing causes static hold. When bits of fabric brush across one other, such as in a hairdryer, an electrostatic charge builds upon them owing to the triboelectric effect. Separately charged positive and negative materials repel each other.
What causes static electricity in winter?
Heat is lower in the cold season. You have a reduced humidity level and reduced aqueous vapor in the air because cold air stores less liquid than hot air. Your skin can hold a bigger charge since there is less moisture vapor in the air to transport the charges away from you.
What causes static electricity in blankets?
Several fabrics are more prone to jolt people in the dead of cold whenever the wind is dry if it pertains to your mattress.
Electrostatic cling is a problem with rayon, acetate, polyester, and nylon, therefore avoid them if at all feasible. Instead, choose a fabric that is more natural, such as cotton, wool, silk, or linen.
What material causes static electricity?
Wool, human hair, dry skin, silk, nylon, tissue paper, plastic wrap, and polyester are substances that prefer to acquire or release electrons, and we may have discovered that they pushed the metal ball identically to the Styrofoam plate once you tested them.
What force causes static electricity?
Substances are held collectively by a force known as the adhesive molecular force.
The adhesive molecular force, on either hand, removes electrons from one substance and deposits them in the other when two dissimilar materials are squeezed together and then torn apart. As a consequence of the ion breakup, static electricity is generated.
How to remove static electricity from the body?
Allowing static electricity to accomplish whatever it desires – release from your skin into the ground – is the quickest approach to get rid of static electricity in the system. Contact any metallic substance that is not separated from the surface, such as a lamp panel bolt or a metal streetlight pole, to enable this.
Friction and dissociation are most likely the most prevalent causes of static in industries that produce film and sheet. It occurs when the material is unwound or travels over a roller. This mechanism is not known exactly, but the best comparison for how static electricity is created here is a comparison with a plate capacitor, in which mechanical power used to divide the plates of a capacitor is turned into electric power.
Whenever the material comes into contact with the roller, a tiny charge is transferred from the substance to the roller, generating an imbalance. The voltage is amplified when the material exits the roller, much like the dividing layers of a capacitor.
In actuality, the magnitude of the resulting voltage is limited by the disintegration power of the adjacent substances, surface conduction, and so on. As the substance exits the roller, you may hear minor crackles of static discharge. This is the point at which the static has exceeded the disintegration power of the neighbouring air.
Sudden Temperature Change
Pyroelectricity is the capacity of some substances to create static electricity when warmed or chilled. Polymer mouldings, in the example, are susceptible to accumulating static charges when they cool following shaping or later temperature processing. Until a plastic product is substantially cold, it is not electrically stable: A common goal temperature for electrical reliability is 40o – 50o C.
High-Intensity Radiation
Although it is uncommon in the industry, exposure to UV, X-rays or high electric fields can result in the formation of a static charge. Plastic films that have been Corona treated to increase printability frequently display unwelcome amounts of static energy.
Action on Cutting
A static charge will be generated throughout the sheet cutting, slashing, and editing procedures. On a single page level, this might not be a big issue, but when numerous sheets or parts are piled, the ‘cell effect’ can build a considerable and potentially dangerous static charge.
Induction
If a controller sporting thermal insulating footwear stands inside the area of a static generating process, then steps away and contacts an earthed object, they may suffer a painful but normally innocuous static release. It can be harmful not because of the electrical jolt, but due to the operator’s uncontrolled ‘recoil’ response.
All matter is made up of atoms. Protons, electrons, and neutrons make up an atom. Neutrons are chargeless, while protons have a positive value and electrons possess a negative charge. As a result, everything is made up of ions. Charges that are diametrically opposed are attracted to one another (negative to positive).
Similar ions oppose one another (positive to positive or negative to negative). Most of the time, positive and negative charges in an entity are balanced, rendering it neutral.
Static electricity is caused by an unbalance of negative and positive ions in a given item. These charges can build up on an object’s surface before being discharged or dissipated. A circuit is one method of discharging them.
Negative ions, or electrons, can be transferred by rubbing certain substances versus one another. When you wipe your shoe on the floor, for instance, your body gathers more electrons. Before they may be liberated, electrons adhere to the human body. You feel a jolt when you reach out to touch your fuzzy pet. Don’t panic, it’s just your excess electrons being delivered to your unwitting pet.
What about the “hair-raising” encounter?
As you discard your hat, electrons flow from the hat to your hair, resulting in that unique hairstyle! Keep in mind that things with equal value repel one another. Your hair will spike on end since they have the equivalent charge.
Your hairs are merely attempting to go as far apart as feasible! Whenever you brush a balloon across your clothing and it adheres to the door, then add an excess of electrons (negative charges) to the balloon’s skin. The balloon now has a higher positive charge than the wall. Since opposites attract, the balloon will attach to the two when they come into touch (positive to negative).

Frequently asked questions| FAQs
Ques. What is a basic understanding of static electricity?
Ans. Static electricity is a well-known electric phenomenon that involves the transmission of charged ions from one object to another.
For example, when two items are rubbed together, the objects accumulate equivalent and contrary charges, particularly if the items are insulators and the nearby air is dry.
Ques. Is static electricity dangerous?
Ans. Static electricity is not harmful, which is fantastic news. Our body is mostly water, and water is an ineffective conductor of electrical current, particularly in such small volumes. That is not to say that electricity cannot harm or kill you.
Ques. How do you remove static electricity from a trampoline?
Ans. To generate more electrical currents on a trampoline, you must produce a lot more resistance. Roll about on the mat, rubbing your hair on the trampoline. If we do this for ten seconds, we should generate sufficient resistance to generate a significant quantity of static electricity.
Ques. How can I avoid static electricity?
Ans. Carrying a safety pin or metallic key in your wallet may be the simplest way to deal with static electricity.
Contacting with it first releases electron charges to protect against shocks. Furthermore, before placing it on clothing, use a metallic hook and gently brush it against them.
Ques. Is there a current in static electricity?
Ans. The charge persists until it can be removed by an electric current or electrical release. Static electricity is distinguished from current electricity by the fact that the electric charge moves via an electrically conducting or vacuum and transfers power.
Ques. How can one distinguish between static electricity and electricity?
Ans. The primary distinction between static and current electricity is that with static electricity, ions are at rest and accumulate on the skin of the insulator. In contrast, electrons move within the wire in current electricity.
Ques. As we touch somebody, why do we sense a current?
Ans. Whenever a body or item has too many electrons, it generates a negative charge. As a result, these electrons are drawn to the positive electrons (reverse attracts) of some other item or person, and vice versa. The fast migration of these electrons causes the shock that humans occasionally experience.
Whatever we see surrounding us is composed of the basic architecture of components known as atoms. They are invisible to the naked eye and are made up of positive ions, negatively charged ions, and neutral neutrons. Almost all of the time, an atom is neutral, which means it has an equal proportion of protons and electrons.
However, when protons and electrons in an atom are in odd numbers, electrons become stimulated. Protons and neutrons do not move, and it is largely electrons that jump.
Ques. What is the charge of a human hair?
Ans. The charge that is negative
According to Thomas, hair generally possesses a negative charge — similar to static electricity — but this is isolated by our hair’s protecting fatty coating. Injured hair has a stronger negative charge, which causes the hairs to physically want to split from one other, resulting in frizz.
If two rocks are hit with one other, a spark is created. All of the kinetic energy in the rocks is pushed from one to another at the instant of impact. If that spot is really small, directing all of that energy through it warms it up and causes it to become loose. A shard of granite breaks free and soars off, remaining heated.
That’s the source of the spark. It works well with particular types of rock that have a proclivity for breaking off very small shards, such as flint. Resistance, instead of impact, can be used, with the friction breaking off pieces.
Stove
A pressure stove features a pressurized chamber and a tip that delivers the vaporized gas into the burner rather than a flame. While using a pressure cooker, there are two factors you should perform. The first step is to pressurize the tank with gas, and the next is to generate sufficient heat to spark the vapor.
Kerosene isn’t as combustible as other petroleum distillates like gasoline or propane, and you can’t light it with a match. As a result, a pressure stove includes a tiny tray in the flame into which distilled alcohol, which is much more combustible, is poured.
You fire the alcohol to warm the burner, then pressurize the tank by pumping it, which vaporizes the kerosene and drives it through the gate and into the stove, where it burns.
A pressurized stove’s fire, and consequently the stove’s heat, may be adjusted in two ways. The control knob, which controls the opening size and volume of gas emitted, may be adjusted. You may also boost the gas pressure by pumping the tank.
Lighter
The piezoelectric effect is used to power the gas lighter (conversion of mechanical stress into electric signal). A piezo-electric stone is inserted within the gas lighter, at one side of the spring, another end of which is attached to a hooked hammer inside the oblong lighter.
To make it particularly harsh, this band on the box includes a little crushed glass. Resistance is created by rubbing the abrasive match head across the abrasive band. This generates just sufficient heat to initiate a chain reaction.
Lighting bulb
The conversion of kinetic energy to light energy is fairly simple. Once you power on the breaker in a DC connection, a movement of electrons, i.e. a large number of electrons, begins to flow from the negative end to the positive end. A filament in a bulb provides impedance to this flow, causing the ions to slow down. This produces heat, and when the temperature rises over a certain point, the filament begins to emit light.
The movement of electrons (traveling electrons have kinetic energy and can-do work) was created by the voltage differential between the ends, and the opposition to this flow produced heat and light. It seems it’s the same with an AC circuit as well.
Sunlight
There will be a large number of helium and hydrogen atoms on the sun. The nuclear fusion of hydrogen nuclei into helium in the sun generates energy (heat and light). A fast (kinetic energy) hydrogen clashes (resistance/friction) with helium, emitting warmth and brightness as a result.
Crackers
A Christmas cracker is a cardboard sheet tubes that has been wrapped in colorful sheets and tied on both ends. Within the cracker is a bouncer, two pieces of chem6ically coated paper that respond with friction and cause the cracker to bang when ripped apart by individuals.
Torch
Whenever a flashlight’s button is turned on, it makes a connection among two touch sheets, which starts a flow of energy supplied by the battery. The cells are linked in such a manner that energy (the movement of electrons) flows between the battery’s positive and negative electrodes.
Display
The liquid crystal substance of a liquid crystal display (LCD) is sandwiched above two layers of glass. Liquid crystal particles are oriented in alignment with the glass plate in the absence of any voltage supplied between clear electrodes. When a voltage is applied, they reverse its orientation and become upright to the glass surface. Based on their alignment, they have different optical properties.
Wireless charging
Wireless chargers generate a magnetic field that your phone, watch, or another gadget absorbs in order to gather energy. When you set a gadget on a wireless charging pad, a tiny coil in the device absorbs and collects magnetic field energy, which it then utilizes to charge the battery.
Tuning forks
A steady electrical circuit stimulates the tuning fork, allowing it to dynamically move. When the fork’s prongs make contact with something of significant mass, the fork’s resonance frequency lowers. This frequency shift is detected by the circuit, which signals the existence of mass touching the fork.
TV remotes
TV remote controls operate in a similar manner, except they use a different form of light known as infrared (or IR for short). The remote control has an LED light that flashes very fast to broadcast a message that is picked up by the TV. The remote is referred to as the transmitter, while the television is referred to as the receiver.

Example of Radiant Energy to Chemical
Radiant energy is a form of energy that travels in waves and can be converted into various other forms. One fascinating example of this conversion is when radiant energy is transformed into chemical energy. In this process, electromagnetic radiation is used to initiate a chemical reaction that stores energy in the form of chemical bonds.
Photosynthesis: Harnessing the Power of Sunlight
One of the most well-known examples of radiant energy being converted into chemical energy is through the process of photosynthesis. Plants, algae, and some bacteria have the incredible ability to capture sunlight and convert it into chemical energy in the form of glucose.
During photosynthesis, plants utilize the radiant energy from the sun to power a series of chemical reactions. The process takes place in specialized structures called chloroplasts, which contain a pigment called chlorophyll. This pigment absorbs light energy, particularly in the red and blue regions of the electromagnetic spectrum.
The absorbed radiant energy is then used to convert carbon dioxide and water into glucose and oxygen. This chemical reaction, known as photosynthesis, is the primary way in which radiant energy is converted into chemical energy by plants. The glucose produced serves as a source of energy for the plant, which can be used for growth, reproduction, and other metabolic processes.
The Chemical Equation of Photosynthesis
The chemical equation for photosynthesis can be represented as follows:
6CO2 + 6H2O + radiant energy→ C6H12O6 + 6O2
In this equation, carbon dioxide (CO2) and water (H2O) are combined using radiant energy to produce glucose (C6H12O6) and oxygen (O2). The radiant energy, in the form of sunlight, is the driving force behind this chemical reaction.
Significance of Photosynthesis
Photosynthesis is not only crucial for plants but also plays a vital role in sustaining life on Earth. Through this process, plants convert radiant energy from the sun into chemical energy stored in glucose. This chemical energy is then transferred through the food chain as organisms consume plants or other organisms that have consumed plants.
Furthermore, photosynthesis is responsible for the production of oxygen, which is essential for the survival of many organisms, including humans. The oxygen released during photosynthesis replenishes the atmospheric oxygen levels, allowing us to breathe and carry out aerobic respiration.
Conclusion
Photosynthesis is a remarkable example of how radiant energy can be converted into chemical energy. Through this process, plants harness the power of sunlight to produce glucose and oxygen, which are vital for their growth and survival. The significance of photosynthesis extends beyond plants, as it plays a crucial role in maintaining the balance of oxygen and carbon dioxide in our atmosphere. By understanding and appreciating the conversion of radiant energy to chemical energy, we can gain a deeper insight into the interconnectedness of life on Earth.
Example of Radiant Energy in Science
Radiant energy is a fascinating concept in the field of science. It refers to the energy that is transmitted through electromagnetic waves.

Whenever a high-velocity water jet fed by a nozzle collides with the bowls of a Pelton wheel, an impulsive force is produced. As a consequence of this pressure, the turbine turns. A generator is powered by the revolving shaft, which generates electricity. In a nutshell, the Pelton turbine converts the kinetic energy of a water jet into rotational energy.
If the machine converts mechanical action to electricity using changing magnetic fields and wire bundles, we can call it a generator. Generators are available in a range of sizes and forms. Stationary coils and whirling magnetic fields, as well as fixed coils and whirling magnetic fields. Linear generators have coils and magnets that travel back and forth in a straight line.
To create DC current, some generators utilize commutators and brushes, while others use slide rings to remove the AC. Others correct AC current to DC current using electrical devices such as diodes. Some produce AC current and are referred to as alternators. Electrostatic generators are also available, which produce extremely strong static electrical voltages.

The vertical axis washer, which sets the clothing in a vertically placed perforated basket housed within a liquid tub, is the most notable characteristic of these washers. In the middle of the basket’s bottom, a finned water-pumping stirrer is inserted. The clothing is inserted via the top of the washer, which is normally covered by a hinged door, but not always.
Throughout the washing process, the agitator’s rotation forces water to circulate, creating a centrifugal force that propels water outwardly between both the paddles and towards the tub’s edge. Since prolonged movement in one way would result in the liquid whirling about the carrier with the stirrer instead of being pushed in a torus-shaped motion, the agitator direction is occasionally reversed.
Some washers assist flow water down in the middle of the basket by supplementing the agitator’s water-pumping motion with a big revolving blade on the spindle above the agitation.
