Answer:
B) Kinetic energy increases, potential energy decreases
Explanation:
In a given system, when a body is at rest, v =0m/s, the kinetic energy is at zero while the potential energy is at maximum. However, when a body is in motion with a velocity = v, the potential energy is at zero while the kinetic energy is at maximum.
Before this happen, the a body at rest (P.E = max) is set on motion, the kinetic energy gradually increases till it converts all the potential energy in the system to kinetic energy and then reverses back when the body goes to rest again.
In this case, before the batter hits the ball, the kinetic energy was at zero while the potential energy was at maximum. However, when he hits the ball and sets it into motion with a velocity V, the potential energy converts to kinetic energy and moves the ball with that energy till it has expanded it and comes to rest.
Potential Energy → Kinetic Energy → Potential Energy.
That's how the system keeps changing.
Speed decreases more the denser the medium.
Since density of a material normally decreases with temperature, it is not surprising that the speed of light in a liquid will normally increase as the temperature increases. (Thus, the index of refraction normally decreases)
Earthquakes does not belong because it is not an electromagnetic wave.
