There is an equation for calcualting the gravitationl potential energy. Eg=m* g* h. (Eg is energy, mis massis gravitational fieldand his height.) On earth g = 10 Nkg, a 25kg balland I want it to have a gravitational potential energy of 1750. how high do have to lift it Plz answer

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.
