3. When a car has a dead 12V battery, it can often be charged up by connecting the 12Vbattery from another car across its terminals.together as are the negative terminals.

The connections are illustrated below. Assume that the current i is measured and found to be 18A and is traveling from car B to car A.The positive terminals are connected a) (3 points) Which car has the dead battery? b) (5 points) Calculate the power (magnitude and sign) of the battery in Car A(absorbed(+) or produced(-))? c) (8 points) If this connection and current is maintained for 3 minutes, how much energy is transferred to the dead battery in joules and in watt-hours.?
