In a proton linear accelerator, a 9.5-mA proton current hits a target.
(a) How many protons hit the target each second?
(b) How much energy is delivered to the target each second if each proton has a kinetic energy of 20 MeV and loses all its energy in the target?
(c) If the target is a 1.00-kg block of copper, at what rate will its temperature increase if it is not cooled?
