A beam of protons is moving toward a target in a particle accelerator. This beam consists of 0.50 mA.
A) How many protons strike the target in 15 s?
B) Each proton has a kinetic energy of 4.9 x 10-12 J. Suppose the target is a block of 15.0 g aluminum and all the kinetic energy goes into heating. What change in temperature will there be in the 15 s?
