The starter motor of a car engine draws a current of 190 A from the battery. The copper wire to the motor is 6.97 mm in diameter and 1.10 m long. The starter motor runs for 0.939 s until the engine starts.178 C is the amount of charge that passes through the starter motor. How far (in m) does an electron travel along the wire while the starter motor is on? Assume that the electron density of copper is 8.5 x1028 m-3.
