[12 points] A traffic engineer has set up a one-mile study segment of a corridor. He measures the speed of 10 vehicles. Calculate the space mean speed and time mean speed of these vehicles. If the space mean speed occurs at an optimal flow with a density of 75 veh/mi, what is the capacity of this roadway

a) the probability of an electron state being filled if it is located at the Fermi level is = 1/2

b) The Fermi level is exactly at the middle of the valence band and the conduction band

c) The Maxwell - Boltzmann approximation accurate to within 10% for
