If you drop a rubber ball it doesn't bounce back to the height you dropped it from. this is consistent with: the second law of thermodynamics.

A solute moving from a high-concentration area to a low-concentration area. Molecules travel passively, following the gradient of concentration from high to low concentration, using NO energy.

The second rule of thermodynamics is a physical principle founded on the knowledge of how heat and energy are transformed throughout the world. A straightforward explanation of the rule is that heat always transfers from hotter to cooler things (or "downhill") unless energy of some kind is used to change the flow of heat.

A difference in the mass of the pod would greatly affect the force required by the thrusters to stop it. The larger the mass of the pod, the more force will be required to stop it. This is because the larger the mass, the more momentum it has and the harder it will be to stop.

The formula for momentum is p = mv, where p is the momentum, m is the mass, and v is the velocity. This means that the larger the mass and velocity of the pod, the more momentum it will have, and the more force will be required to stop it.

To stop the pod, the thrusters will need to exert an equal and opposite force to the momentum of the pod. This will cancel out the momentum and bring the pod to a stop. The larger the mass of the pod, the more force the thrusters will need to exert to cancel out the momentum and bring the pod to a stop.

Several factors can affect the mass of the pod, including the materials used in its construction, the payload it carries, and any additional equipment or systems it may have. For example, if the pod is made of lighter materials, it will have a lower mass and require less force to stop it. On the other hand, if the pod carries a heavy payload or has additional equipment installed, it will have a higher mass and require more force to stop it.

A difference in the mass of the pod would have an effect on the amount of force needed to be exerted by the thrusters to stop it. This is because a pod with a large mass would require a lot of force to stop it. An object with a large mass will gain more momentum requiring more force to stop it.

The momentum formula is p = mv;

p represents momentum,

m is the mass,

v is the velocity.

This explains why a pod with a large mass will have more momentum and requiring more force to exerted to stop it.

So as to stop the pod, the thrusters will be required to exert an opposite and force which will eventually bring the pod to a stop.

The pod mass is determined by some factors such as the materials its made of and any load that its carrying. So, a pod made of heavy materials will need a lot of to be exert to stop it but one made of lighter materials will require less force to bring to a stop

Explanation:

To find the time it will take a motor to lift a load to a given height, we need to use the formula for power.

The formula for power is given by:

P = W/t

where P is the power of the motor, W is the work done by the motor, and t is the time it takes for the motor to do the work.

In this case, we are given that the power of the motor is 200 Watts, the weight of the load is 80 kg, and the height to which the load is lifted is 2 meters. We can use these values to solve for the time it takes for the motor to lift the load.

First, we need to calculate the work done by the motor. The work done by the motor is equal to the weight of the load multiplied by the height to which the load is lifted:

W = F * d

W = 80 * 2

W = 160

Next, we can use the formula for power to solve for the time it takes for the motor to lift the load:

P = W/t

200 = 160/t

t = 1.25

Therefore, it will take the motor 1.25 seconds to lift the 80 kg load to a height of 2 meters.

Answer:

There are several advantages to the high specific heat capacity of water. Some of the key advantages are:

1.Water can store a large amount of heat energy without undergoing significant temperature changes. This means that water can help to regulate the temperature of the Earth and other bodies of water, providing a stable environment for life to thrive.

2.The high specific heat capacity of water allows it to act as a buffer against temperature changes. For example, when the temperature outside is very hot, water bodies such as oceans and lakes can absorb some of the heat energy, preventing the temperature from getting too high. Similarly, when the temperature outside is very cold, water bodies can release some of their stored heat energy, helping to keep the temperature from dropping too low.

3.The high specific heat capacity of water also makes it a useful heat transfer medium. Water can be heated and then used to transfer heat to other objects, such as in a radiator or a steam engine. This allows water to be used in a variety of industrial and domestic applications.

A 12 kilogram cart is moving at a speed of 0.25 meter per second after the speed of the cart is tripled the inertia of that cart will be will be 12 kilograms.

The inertia of an object is a measure of its resistance to changes in its state of motion. Inertia is directly proportional to the mass of the object. This means that if the mass of an object is increased, its inertia will also increase. In this case, the mass of the cart is 12 kilograms, and its speed is 0.25 meters per second. If the speed of the cart is tripled, the inertia of the cart will not change because the mass of the cart remains the same. The inertia of the cart will still be 12 kilograms. It is important to note that the speed of an object does not affect its inertia. Inertia is determined solely by the mass of the object. Every item maintains its condition of uniform motion in a straight direction or of rest unless it is compelled to do otherwise by forces applied to it.

Inviscid flow region and boundary regions are the salient features of a hydrodynamic entry region, a thermal entry region are hydrodynamic and thermal entry lengths equivalent.

A material's capacity to conduct heat is determined by its thermal conductivity. In contrast to materials with high thermal conductivity, low thermal conductivity materials transmit heat more slowly. For instance, insulating materials like Rockwool or Styrofoam are effective at retaining heat while metals often have high thermal conductivity and are very effective at transferring heat. In line with this, materials with high thermal conductivity are frequently used as heat sinks, whereas those with low thermal conductivity are employed as thermal insulation. Thermal resistance is the inverse of thermal conductivity. Working with numbers that are derivatives of thermal conductivity and that implicitly account for design-specific details like component dimensions is a typical practice in engineering. For instance, the amount of heat that travels through a plate of a certain area and thickness in a unit of time when the temperatures on its opposing faces differ by one kelvin is known as thermal conductance.

It will take the boat 5 seconds to cross the river.

To determine how long it takes the boat to cross the river, we need to take into account the speed of the current as well as the speed of the boat.

The speed of the boat relative to the water (the speed of the boat plus the speed of the current) is given by the equation:

v_rel = v_boat + v_current

where v_rel is the speed of the boat relative to the water, v_boat is the speed of the boat in still water, and v_current is the speed of the current.

In this case, the speed of the boat in still water is 4 m/s and the speed of the current is 2 m/s. Plugging these values into the equation gives us the speed of the boat relative to the water of:

v_rel = 4 m/s + 2 m/s = 6 m/s

To determine the time it takes the boat to cross the river, we can use the equation:

t = d / v

where t is the time, d is the distance to be traveled, and v is the speed.

In this case, the distance to be traveled is 30 m and the speed is the speed of the boat relative to the water (6 m/s). Plugging these values into the equation gives us a time of:

The Doppler effect is a phenomenon that occurs when two objects move closer or farther apart, increasing (or decreasing) the frequency of sound, light, or other waves. A source's waves are compressed as they move in the direction of the observer.

The Doppler effect operates as follows: When a loud object approaches you, its sound waves congregate and increase in frequency or pitch. On the other hand, the sound waves spread apart and the pitch drops as the object moves away from you. The pitch change increases with object speed.

The Doppler effect causes the frequency of light waves coming from moving sources to either shift to the blue or red. This behaves in a way that is similar to other types of waves, such sound waves, but not exactly the same.

Answer:

approx. 147 units of work

Explanation:

To find the amount of work you do when you lift your sister to a given height, we need to use the formula for work.

The formula for work is given by:

W = F * d

where W is the work done, F is the force applied, and d is the distance moved.

In this case, we are given that the weight of your sister is 10.0 kg, the height to which you lift her is 1.5 meters, and the acceleration due to gravity is 9.8 m/s^2. We can use these values to solve for the amount of work you do when you lift your sister.

First, we need to calculate the force applied by you. The force applied by you is equal to the weight of your sister divided by the acceleration due to gravity:

F = m * a

F = 10.0 * 9.8

F = 98

Next, we can use the formula for work to solve for the work done when you lift your sister:

W = F * d

W = 98 * 1.5

W = 147

Therefore, you do approximately 147 units of work when you lift your 10.0 kg sister to a height of 1.5 meters. This result is not exact because the value of the acceleration due to gravity is an approximation

Kinetic Energy = 1/2 x mv²

m = the gas's mass

v - the gas's speed

As a result, the square of the gas's velocity is directly proportional to its temperature.

The root mean square velocity will double if the velocity of every atom doubles.

As well as this, we are aware of root mean square velocity Vrms = v(3RT/molar mass).

Therefore, Vrms is inversely proportional to T's square root (temperature )

Vrms = √T

if temperature increase by a factor of 2,
