15. You are unloading a 35 kg fridge from the back of a truck. It slips out of your hand and rolls down the ramp that is 1.2 m tall and 3.1 m long. The force of friction on the fridge is 45 N.
a.
How much thermal energy is produced by the time the fridge gets to the bottom of the ramp?
b. How fast will the fridge be moving at the bottom of the ramp?
C. If you need to push an identical fridge back up the ramp in 15 s, how much power would you need
to generate?

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?
