(4 points) For an electron number density of ne = 6 x 10^27 cm^-3, calculate and plot the momentum distribution [n(p) versus p] of electrons using the Maxwell-Boltzmann distribution and also the distribution for non-relativistic degenerate gas for (a) T = 2 x 10^8 K. (b) T = 2 x 10^7 K. (c) T = 2 x 10^6 K.
