Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. The tank is buried so that the top of the tank is 1 meter below ground level. The space above the tank is not filled with water. Calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (The water weighs 9,800 newtons per cubic meter.)

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.
