Solve all problems given last week for network laws and theorems using Maxwell's Mesh method. Compare results using Nodal for problems related to unknown potentials or voltage drops.

Problem#1.
Find the maximum kinetic energy of emitted particle and that of the residual nucleons from the radioactive decay of [(a) scandium - 46 (0.889MeV); (b) arsenic - 76 (0.559MeV)]. The energy quantities in parenthesis are the amounts of gamma ray energy emitted in each of the decay processes. If one tonne of the isotope was present when the earth was formed 4.5 billion years ago, either determine the number of atoms existing at this time (if greater than 10 raised to the 10th power atoms) or determine how many years it took for the number of atoms to drop to 10 raised to the 10th power.
