Question

You have a 12.0-V motorcycle battery that can move 5000 C of charge, and a 12.0-V car battery that can move 60,000 C of charge. How much energy does each deliver? (Assume that the numerical value of each charge is accurate to three significant figures.)

Answer 1

Energy (in joules) = Voltage (in volts) x Charge (in coulombs)

1. Motorcycle battery:

Energy = 12.0 V * 5000 C = 60,000 joules

2. Car battery:

Energy = 12.0 V * 60,000 C = 720,000 joules

So, the motorcycle battery delivers 60,000 joules of energy, while the car battery delivers 720,000 joules of energy.
