You are running an experiment that uses an accelerator that produces a 3.50-µA proton beam. Each proton in the beam has 48.5-MeV of kinetic energy. The protons impinge on, and come to rest inside, a 51.0-g copper target within the vacuum chamber. You are concerned that the target will get too hot and melt the solder on some connecting wires that are crucial to the experiment.
(a) Determine the number of protons that strike the target per
(b) Find the amount of energy delivered to the target each second.
(c) Determine how much time elapses before the target temperature increases by 271° C. (Neglect any heat released by the target. The specific heat of copper is 0.386 kJ/kg · K.)
