free electron

Q1: Assuming that each copper atom contributes one free electron for conduction, find the conductivity (sigma) at room temperature given that mean free time is 2.48e-14 at this temperature. Note density of copper=8.3gm/cm3, at weight=63.6, Avogadro number, electron charge and mass of electron being as usual.

(Calculate mass, properly ,as I had problem in mole, density and at weight relations!).

 

Q2: A bit Calculus problem, but I can replace it, But it is not that hard! Just solve the integral!

Solve the integral that is given in following file "Selection" in Q no 3! Do each step (in detail)!
