Question

what evidence supports the claim that energy is flowing in the picture below.

□ the wheel moves
□ the water moves
□ the water is cold
□ the water doesnt move
□ the wheel doesnt move

Explanation:

Energy flow is indicated by movement. The wheel moving shows energy transfer from water (kinetic energy of flowing water) to the wheel (mechanical energy of rotation). The water moving shows its own kinetic energy (a form of energy in motion). The temperature of water (being cold) is about thermal energy but not directly about energy flow in the context of the wheel - water interaction. If water doesn't move or wheel doesn't move, there is no obvious energy transfer or flow (as energy flow often involves work done, which is related to motion in this case).

Answer:

the wheel moves, the water moves
