Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
