question

Protons of mass 1.67 × 10^-27 kg and moving with a velocity of 2 × 10^7 m \textbullet s^-1 strike a target of mass1 g and specific heat capacity 0.334 cal \textbullet g^-1 \textbullet C deg^-1. The proton stream corresponds to a current of 4.8\muA. At what rate does the temperatureof the target initially rise if one-third of the energy of the protons is converted into heat?
