A technician wraps wire around a tube of length 4pi^2 cm having a diameter of 8.00cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 1000turns of wire. If the current in this solonoid increases at the rate of 4.00A/s the self-induced emf in the solenoid is
