How long does it take electrons to get from the car battery to the starting motor? Assume the current is 140 A and the electrons travel through copper wire with cross sectional area 28.9 mm2 and length 79.1 cm. The mass density of copper is 8960 kg/m3 and the molar mass is 63.5 g/mol. Assume that each copper atom contributes one conduction electron.
