a) (1.16)(9.99x10^4) = 11.5884x10^4
b) (2.86x10^-8 ) - (5.31x10^-9) = 2.329x10^-8
c) 12pi/ (4.76x10^-3) = 7919.98
d) 24.8 + (5.99x10^2) = 623.8

the momentum of the object is the product of mass and velocity.
now momentum = mass x velocity = mass x (velocity/time) x time
= mass x acceleration x time = force x time

As I mentioned in the class assume that we have a GaAs (Gallium
Arsenide) sample which was doped with excessive As to produce a
resistivity of 0.05 Ωm. Owing to the presence of an unknown
acceptor impurity the actual resistivity was 0.06Ωm, the sample
remaining n-type. What were the concentrations of donors and
acceptors present?
