Answer:
Non-renewable energy comes from sources that will run out or will not be replenished for thousands or even millions of years. Most sources of non-renewable energy are fossil fuels. Fossil fuels were created as the remains of marine creatures decayed millions of years ago, under huge amounts of pressure and heat. Most fossil fuels are burned to create energy and electricity. Coal, above, is a type of rock that is a fossil fuel.

Answer:
Vaporization occurs when a substance changes from a liquid to a gas. The molecules in a liquid are in constant motion while staying relatively close together due to intermolecular forces. When an increase in temperature occurs, the molecules' kinetic energy also increases. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.

Hardness, color , and luster.
But since you can pick one, I would say hardness
Impulse = mass * change in velocity (change in momentum) = Force * change in time
So, F=(m*change in v)/(change in t)
F=(60*20)/0.5=2400N
Therefore the magnitude of the average force exerted on the cyclist by the haystack is 2.4*10^3N
