Q1. A solenoid is formed by winding 26.9 m of insulated silver wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and the insulating coat on the wire is negligibly thin. When the solenoid is connected to an ideal (no internal resistance) 2.73-V battery, the magnitude of the magnetic field inside the solenoid is found to be 5.83 10-3 T. Determine the radius of wire.
Q2. How much force, in Newtons, is needed to accelerate a truck with a mass of 1500 kilograms from a full stop to 40 m/s in 10 seconds if the rate of acceleration is constant?
