In nuclear power plants, atoms are split apart to form smaller atoms releasing energy 20 in a process called nuclear fission. Calculate the electrical power that is released in one hour due to splitting 200 g of Uranium-235, taking the disintegration energy per event to be 208 MeV.
A particle of mass m, is fired at a stationary particle of mass mg, and a reaction takes place in which new particles are created out of the incident kinetic energy. Taken together, the product particles have total mass mg. The minimum kinetic energy the bombarding particle must have so as to induce the reaction is called the threshold energy. At this energy, the kinetic energy of the products is a minimum, so the fraction of the incident kinetic energy that is available to create new particles is a maximum. This condition is met when all the product particles have the same velocity and the particles have no kinetic energy of motion relative to one another.
