A beam of protons is moving toward a target in a particle accelerator. This beam constitutes a current whose value is. (a) How many protons strike the target in 12 seconds? (b) Each proton has a kinetic energy of J. Suppose the target is a 18-gram block of metal whose specific heat capacity is , and all the kinetic energy of the protons goes into heating it up. What is the change in temperature of the block at the end of s?
