Answer:
<em>The atoms in the hot bodies have higher kinetic energy than those of the cold bodies. Thus to maintain thermal equilibrium, the atoms of higher kinetic energy tries to move and collide with the atoms of low kinetic energy. Thus heat transfers from a hot body to a cold body.</em>
<em>Explanation:</em>

c
Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of kinetic energy, which is less than the initial amount of potential energy.
remember the law of energy there cannot be any more since it is using the potential energy to move
C) Some of the light's energy is absorbed by the wall, and some of the light is reflected in different directions
Answer:
Explanation:
According to Newton's second law, the tension in the string is equal to the centripetal force, since the mass is under an uniform circular motion:
Here is the centripetal acceleration, which is defined as:
So, replacing:
In this case we have , and . Thus, the tension required to mantain uniform circular motion is:
