Match it! Select the correct answer from the pull down...Good luck!

A light wave strikes the Moon and reflects toward Earth. As the light wave travels from the Moon toward Earth, the wave carries

If PE is the gravitational potential energy of A relative to the ground, then the gravitational potential energy of B relative to the ground is

A horizontal force of 20 newtons eastward causes a 10-kilogram box to have a displacement of 5 meters eastward. The total work done on the box by the 20-newton force is

A block initially at rest on a horizontal, frictionless surface is accelerated by a constant horizontal force of 5.0 newtons. If 15 joules of work is done on the block by this force while accelerating it, the kinetic energy of the block increases by

A 5.8 × 10^4-watt elevator motor can lift a total weight of 2.1 × 10^4 newtons with a maximum constant speed of

What is the sign of the net charge on A and B?

A stationary police officer directs radio waves emitted by a radar gun at a vehicle moving toward the officer. Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a

A motor does a total of 480 joules of work in 5.0 seconds to lift a 12-kilogram block to the top of a ramp. The average power developed by the motor is
