Question

Which best describes a similarity between power plants that use water as an energy source and those that use wind as an energy source?

A.Both use heat from within Earth to produce electricity.
B.Both use kinetic energy to produce electricity.
C.Both use resources that are not abundant.
D.Both use resources that produce a lot of air pollution.

Answer 1

The correct answer to the question is : B) Both use kinetic energy to produce electricity.

Step-by-step explanation:

Hydroelectricity is produced when the kinetic energy of the falling water rotates the turbine. The generator associated with the turbine is rotated, and electric energy is produced due to electric magnetic induction.

In case of power plants in which wind is used as energy source, the same process happens. The kinetic energy of wind rotates the propellers of wind turbine which in turn produces electric energy.

Hence, the correct similarity between them is statement B.

Answer 2

The hydropower plant and wind turbines both uses kinetic energy to produce mechanical power and convert the mechanical energy using a generator to an electrical energy. They both have the process to produce energy but they differ in the source the hydropower plant uses water to whit the wind turbines power plant uses wind. Therefore the answer is letter B.
