In beta decay of a nucleus, an electron is emitted. if the nucleus is assumed to consist of protons and electrons, calculate the minimum energy of the electron confined within a nucleus of radius 1.5 fm., using heisenberg's uncertainty relation. calculate also the minimum energy of the proton confined within the nucleus.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
