The density of copper is 8.92x10^3 kg/m3 . The resistivity is 1.73x10 ^-8 Ω m and the weight of a copper atom is 63.5 amu (atomic mass unit). (i) Assuming each Cu atom contributes one conduction electron, calculate the electron mobility and the average time between collisions (relaxation time). (ii) Calculate the Fermi energy, Fermi wavevector, Fermi velocity and Fermi temperature.

help its urgent please

Expert Solution

The mobility and relaxation time of electrons in Cu can be determined using Drude's Free electron theory model. The Fermi energy, Fermi wavevector, Fermi velocity and Fermi temperature can be determined using Fermi-Dirac analysis.

Copper wire has a resistivity ρ = 1.7 × 10-8 Ω⋅m when at 20°C and it has a temperature coefficient α = 3.9 × 10-3 K-1. A solid cylinder of copper of length L = 45 cm and diameter D = 1.5 mm has one end held at T1 = 6°C and the other end is held at T2 = 270°C. The temperature increases linearly between the two ends of the cylinder. Determine the total resistance in milliohms.

An 80 kg skydiver falls through air with a density of 1.15 kg/m3 . Assume that his drag coefficient is C=0.57. When he falls in the spread-eagle position his body presents an area A1=0.94 m2 to the wind, whereas when he dives head first, with arms close to the body and legs together his area is reduced to A2=0.21 m2 . What are the terminal speeds in both cases?
