When a raw egg is thrown against a wall, the wall is a hard and unyielding surface. The force of the impact causes the eggshell to break.

As the egg cannot withstand the sudden stop against the wall.

On the other hand, when a raw egg is thrown at a sagging sheet, the sheet provides a surface that is more forgiving. The sheet gives way when the egg hits it, and the force of the impact is spread out over a larger area.

This means that the egg does not experience the same sudden stop that it would if it hit a hard wall. Additionally, the sagging sheet provides a bit of cushioning, which also helps to absorb some of the force of the impact.

Overall, the reason why a raw egg breaks when thrown against a wall but not when thrown at a sagging sheet is due to the difference in the surfaces that the egg hits.

The hard, unyielding surface of the wall causes the egg to break, while the soft, yielding surface of the sagging sheet allows the egg to survive the impact.

Yes, a friction force to the right acts on the furniture.

The force preventing solid surfaces, fluid layers, and material components from sliding past one another are known as friction. When surfaces in contact move past one another, the friction between the two surfaces transforms kinetic energy into thermal energy (that is, it converts work to heat). As demonstrated by the utilization of friction produced by rubbing pieces of wood together to start a fire, this feature can have dramatic effects. Every time there is motion with friction, such as when a viscous fluid is agitated, kinetic energy is transformed into thermal energy. Wear is a significant side effect of several types of friction that can result in deteriorated performance or component damage. The discipline of tribology includes friction.

According to conservation of energy, the energy of interacting bodies in a closed system remains constant. The total energy of an isolated system remains constant; it is said to be conserved over a period of time.

Elastic energy is the mechanical implicit energy stored in the configuration of a material or physical system as it's subjected to elastic distortion by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally misshaped in any manner.

The mechanical energy is never lost forever , rather it gets converted to thermal energy because of the friction .

Answer:

Explanation:

In projectile,

Maximum height = \(\frac{u^{2}sin^{2} \theta }{2g}\) and range = \(\frac{u^{2}sin2\theta }{g}\)

u = velocity of the body

\(\theta\) = angle of launch

g = acceleration due to gravity

If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;

\(\frac{u^{2}sin^{2} \theta }{2g} = \frac{u^{2}sin2\theta }{g}\)

since \(sin2\theta = 2sin\theta cos\theta\)

\(\frac{u^{2}sin^{2} \theta }{2g} = \frac{u^{2}2sin\theta cos\theta }{g}\\\frac{sin\theta}{2} =2cos\theta \\sin\theta = 4cos\theta\\\frac{sin\theta}{cos\theta} = 4\\tan\theta = 4\\\theta = tan^{-1} \\4\theta = 75.9^{0}\)

The angle at which the range equals the maximum height in an ideal projectile launch on a horizontal plane is approximately 76°

Answer: Different types of fuels have varying compositions and release different amounts of pollutants when burned. Here are some common types of fuels and the pollutants associated with them:

Fossil Fuels:

a. Coal: When burned, coal releases pollutants such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM).

b. Petroleum (Oil): Burning petroleum-based fuels like gasoline and diesel produces CO2, SO2, NOx, volatile organic compounds (VOCs), and PM.

Natural Gas:

Natural gas, which primarily consists of methane (CH4), is considered a cleaner-burning fuel compared to coal and oil. It releases lower amounts of CO2, SO2, NOx, VOCs, and PM.

Biofuels:

Biofuels are derived from renewable sources such as plants and agricultural waste. Their environmental impact depends on the specific type of biofuel. For example:

a. Ethanol: Produced from crops like corn or sugarcane, burning ethanol emits CO2 but generally releases fewer pollutants than fossil fuels.

b. Biodiesel: Made from vegetable oils or animal fats, biodiesel produces lower levels of CO2, SO2, and PM compared to petroleum-based diesel.

Renewable Energy Sources:

Renewable energy sources like solar, wind, and hydropower do not produce pollutants during electricity generation. However, the manufacturing, installation, and maintenance of renewable energy infrastructure can have environmental impacts.

It's important to note that the environmental impact of a fuel also depends on factors such as combustion technology, fuel efficiency, and emission control measures. Additionally, advancements in clean technologies and the use of emission controls can help mitigate the environmental impact of burning fuels.

When you hold your cardboard square between the lights source and the wall you observe a shadow.

We know that light is a source of energy. Light travels in straight lines and this is called the rectilinear propagation of light. Having known that light travels along a straight path, we know that light would pass through the cardboard which is not too thick.

This cardboard is now able to scatter the light waves. We would then see a shadow at the wall. This shadow would have two regions; the region of complete darkness called umbra and the region of partial darkness called penumbra.

The magnification of the image formed by the lens is -0.982.

To determine the magnification of the image formed by the lens, we can use the lens formula:

1/f = (n - 1) * (1/r1 - 1/r2)

Where f is the focal length of the lens, n is the refractive index of the lens material, r1 is the radius of curvature of the front surface, and r2 is the radius of curvature of the back surface.

Given that the radii of curvature are 34.5 cm and -26.9 cm, and the refractive index is 1.66, we can substitute these values into the lens formula to calculate the focal length.

Using the lens formula, we find that the focal length of the lens is approximately 13.54 cm.

The magnification of the image formed by the lens can be determined using the magnification formula:

m = -v/u

Where m is the magnification, v is the image distance, and u is the object distance.

Given that the object is placed 42.6 cm from the lens, we can substitute this value and the focal length into the magnification formula to calculate the magnification.

Substituting the values, we find that the magnification of the image formed by the lens is approximately -0.982.

Answer: The dimensions of wellness do not influence each other.

Explanation: The answer is true.

False im sure. correct me if im wrong.

When an object is placed farther from a convex mirror than the focal length, the image is smaller and virtual.

The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point. As the object approaches the mirror the image also approaches the mirror and grows until its height equals that of the object. A convex mirror always creates a virtual image which is diminished. So, magnification produced by convex mirror is always less than one. So, When an object is placed farther from a convex mirror than the focal length, the image is smaller and virtual.

In the electron-transport chain, as electrons move along a series of carriers, they release energy that is used to pump protons across a membrane.

In plants and animals, the electron transport chain points to the consistent streaming of electrons across cells where electron donors donate electrons and electron acceptors accept electrons through an oxidation-reduction reaction.

As a result of the oxidation-reduction reaction, an electrochemical gradient is created and ATPs are generated for energy purposes.

Moreover, the chain comprises 4 key protein complex molecules that are transferred across the plasma membrane cell.

This cellular process takes place in mitochondria and is responsible for chemical reactions such as photosynthesis and cellular respiration. The four principle steps of this process are Krebs' cycle, glycolysis, oxidative phosphorylation, and pyruvate oxidation.

linear and angular velocity are related

         v = w r

let's substitute

         a = w² r

the angular velocity is related to the period

        w = 2π / T

we substitute

        a = \(\frac{4\pi ^2 \ r}{T^2}\)

        a = 7.4 m / s²

Explanation:

The force of gravity on a woman who weighs 926 N on the surface of the earth is 926 N. The weight of an object is a measure of the force exerted on the object due to gravity, and is equal to the mass of the object multiplied by the acceleration due to gravity. On the surface of the Earth, the acceleration due to gravity is approximately 9.8 m/s^2.

Answer:926N

Explanation:

Force=926N.

The units of force are in N (Newtons). The units of weight are in Kg (Kilograms)

Force = Mass * Acceleration

On the surface of the Earth, the acceleration would be gravity, 9.81m/s²

If calculating mass...

F=mg

926N=m(9.81m/s²)

Where:

Information about the problem:

Applying the final velocity formula, and clearing the time we get:

vf = vi + (a * t)

t = (vf – vi) /a

t = (0 m/s – 87 m/s) /-8.55 m/s²

t = -87 m/s/ -8.55 m/s²

t = 10.1754 s

Applying the distance formula, we get:

x = (vf²-vi²)/ (2a)

x = [(0 m/s)²- (87 m/s)²]/ (2 * -8.55 m/s²)

x = (0 m²/s²- 7569 m²/s²)/ -17.1 m/s²

x =  -7569  m²/s²/ -17.1 m/s²

x = 442.63 m

By converting the distance units form (m) to (km) we have

x = 442.63 m * 1 km/1000 m

x = 0.44263 km

It is a physical quantity that indicates the variation of velocity as a function of time, it is expressed in units of distance per time squared e.g.: m/sec2 ; km/h2

Answer:

Clouds form when below the dew point

Clouds form when the air is cooled below the dew point. The dew point is the temperature at which the air becomes saturated, meaning it can no longer hold all the water vapor it contains. The correct answer is the dew point.

When the air cools below this temperature, the excess water vapor condenses into tiny water droplets or ice crystals, forming clouds.

The dew point is an important concept in meteorology and refers to the temperature at which the air becomes saturated, leading to the formation of dew, fog, or clouds. It is the temperature at which the air can no longer hold all the water vapor it contains, resulting in the condensation of water vapor into liquid water droplets.

When air is cooled, its capacity to hold water vapor decreases. As the temperature drops, the air reaches a point where it becomes saturated, meaning the air is holding the maximum amount of water vapor it can at that specific temperature and pressure. This temperature is known as the dew point.

Therefore, while relative humidity, water content, and percent saturation are relevant factors in understanding the moisture content of the air, clouds specifically form when the air is cooled below the dew point. The correct answer is the dew point.

The x-component of the total momentum of the system at time t can be expressed as \(m_{1} v_{1} (t)+ m_{2} v_{2} (t)\) in terms of m1 , m2 , v1(t) , and v2(t) .

The momentum of the body is represented as the product of its mass and velocity;

p= m×v

Where, m is the mass of a particle and v is its velocity

The momentum of the whole system is the vector sum of individual momentum of all the particles, which can be represented as

\(p_{net}\)=\(p_{1}\) + \(p_{2}\) + \(p_{3}\) +...

The X-component of the momentum of the system is:
