The region between x = 0 and x = d is free space and has v = 0(x — d)/d. If V(x = 0) = 0 and V(x = d) = V0, find: (a) V and E, (b) the surface charge densities at x = 0 and x = d.

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.

Metals are good conductors of electricity because they
