An automobile starter motor is an electric motor used to start the gasoline engine. To operate the starter motor, the ignition switch is turned on, and a current of 55 A is supplied through a 1.9 mm radius copper wire that connects the motor to the automobile battery. (The density of free electrons of copper is 8.50 x 1028/m3.)(a) If electric charge had to travel the 0.52 m distance from the battery to the motor before the motor would operate, how long would it take?(b) How far do the electrons move in the 2.2 s required to start the engine?
