When -3.72*10^-4 C charge moves from point A to point B its electric potential energy increases by 0.218 J. What is the potential difference between A and B?

Abicycle slows down when the rider applies the brakes. what type of energy transformation is involved in this example? a. kinetic energy into heat energy b. heat energy into potential energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
