Question: (a) Given a mean free path = 0.4 nm and a mean speed vav = 1.17 105 m/s for the current flow in

(a) Given a mean free path λ = 0.4 nm and a mean speed vav = 1.17 × 105 m/s for the current flow in copper at a temperature of 300 K, calculate the classical value for the resistivity ρ of copper.

(b) The classical model suggests that the mean free path is temperature independent and that vav depends on temperature. From this model, what would ρ be at 100 K?
