The starter motor of a car engine draws a current of 140a from the battery. the copper wire to the motor runs for 0.90s until the car engine starts. how much charge passes through the starter motor?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
