A 4.12 g lead bullet moving at 300 m/s strikes a steel place and stops. If all its kinetic energy is converted to thermal energy and none leaves the bullet, what is its temperature change?
Calculate BE/A, the binding energy per nucleon, for 58Ni. Among the most tightly bound of all nuclides, it is more than 65% of natural nickel. Note that 58Ni has even numbers of both protons and neutrons.
