Assume this 1.20-mm-radius copper wire is electrically neutral in the earth reference frame, in which it is at rest and carrying a current. calculate the linear charge density λ′ of the copper wire in a reference frame moving along with the electrons if the electrons are moving at 5.20 ×10−4m/s .

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
