What are fossil fuels??? I don't want examples like "coal," I want you to explain how and why they exist.
Fossil fuels are the remains of organic material from millions of years ago.

True or false: Potential energy can only be converted into chemical energy.
FALSE

Which bow requires LESS mechanical energy from the human to shoot. Can you explain how this is possible?
The compound bow (on the right) requires less mechanical energy from the human because it uses pulleys (little wheels) to make it easier.

You have to live in the desert and need to produce energy. What is the best source of non-renewable energy in the desert??
Solar, I image. Make some solar panels
400
Explain what would happen if we had no fossil fuels
I'm not sure

EXPLAIN; there are 3 sources of heat here, fireplace, lantern, and electric radiator. Explain how each one uses/converts/produces energy.
Fireplace; the potential energy of the wood is burned in a chemical reaction to produce thermal energy and light energy. \
Lantern: basically same as fireplace
Radiator: electric energy converted into thermal energy

Are there some disadvantages to wind farms? If no why not and if yes what are they?
Damage to habitat, some say they're ugly, if there's no wind there's no energy, they cause cancer (says Donald Trump)

Explain what sources of energy are being used and being produced by playing this instrument (it's called a theremin)
Electrical energy reaches the instrurment and when the man uses kinetic energy from his hands he produces sound energy/waves
