An electric motor has an effective resistance of 22 22 and an inductive reactance of 72 12 when working under load. the voltage amplitude across the alternating source is 420v. calculate the current amplitude. in a.

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
