Electric power is to be generated by installing a hydraulic turbine generator at a site 120 m below the free surface of a large water reservoir that can supply water at a rate of 2400 kg/s steadily. determine the power generation potential.

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

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.

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
