Answer:
a) kinetic energy and gravitational potential energy
Explanation:
The water at the top of the fall possesses kinetic energy because the water is in motion, moving.
The water at the top also possess gravitational potential energy because it is falling under the influence of gravity. It is in a gravitational field.
The RATE of producing, moving, converting, or using energy is "power".
The unit is "watt". 1 watt means 1 joule of energy per second.
