Atomic and Nuclear Physics
The following fission reaction is a typical of those occuring in a nuclear electric generating station.
(1_0n) + (235_92U) → (141_56Ba) + (92_36Kr) + 3(1_0n)
(a) find the energy in the reaction. The mass of neutron = 1.008665u, mass of Ba-141 = 140.914411u, mass of Kr-92 = 91.926156u and mass of U-235 = 235.043930u

A wooden artifact is found in an ancient tomb. Its carbon-14 activity is measured to be 60% of that in a fresh sample of wood from the same region. Assuming the same amount of C-14 was initially present in the artifact as is now contained in the fresh sample, determine the age of the artifact.
