*will mark brainliest! answer asappp* which of these statements about hydroelectric power is true? a. it uses water's potential energy to produce electricity b. it disrupts one of earth's never-ending cycles c. it uses a safe, renewable resource d. it uses civilization's earliest energy resource

A. it uses water's potential energy to produce electricity

Explanation:

The water is stored at a height in a dam. Potential energy is stored  in water. The water is allowed to fall down on turbine. The potential energy converts to kinetic energy which makes the turbine rotate which is connected to a generator. The mechanical energy converts to electrical energy.  This how potential energy stored in water is harnessed to produce electrical energy in hydroelectric power plants.

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
