According to the picture, how would the gravitational potential energy of the car change if its weight was doubled? a) the gravitational potential energy would be doubled. b) the gravitational potential energy would stay the same c) the gravitational potential energy would be cut in half. d) the gravitational potential energy would be increased by 750.

Ahydroelectric plant takes energy from water and turns it into electrical energy. what are the transformations of energy in the water molecules that are used in the process of generating electricity this way?

When you turn on a battery-operated device, an electrical circuit is

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
