Question

select the correct answer. which description is an example of gravitational potential energy transforming into kinetic energy? a. water flowing downhill and spinning turbines b. upward currents of wind spinning blades of a windmill c. plants performing photosynthesis d. loudspeakers producing sound from electrical signals

Explanation:

Gravitational potential energy is energy an object has due to its height in a gravitational field. Kinetic energy is energy of motion. Water flowing downhill has its height - related gravitational potential energy converted into the kinetic energy of its motion which spins turbines. Option B is wind - related kinetic energy, C is light - to - chemical energy conversion in photosynthesis, and D is electrical - to - sound energy conversion.

Answer:

A. water flowing downhill and spinning turbines
