A scientific test that might support or disapprove a hypothesis

answer; i believe the answer is hydraulic action;

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

the answer is either a. or d. if you're talking about fully electric cars, then the answer is a. if you're talking about hybrid cars, the answer would be d.
