_ _ _ _ _ energy is energy that is currently in use (or motion)
noname [10]
Your answer is correct.

I like to remember the difference between kinetic and potential energy as potential energy “has the potential to move” as it stores energy and kinetic energy is when something “is kicked.” ATP relates to an entirely different process so that answer can be eliminated and the definition is accurately provided in one of the answer choices so D can be eliminated as well.

I hope this helps! :)

What part of a nuclear fuel rod is reused for nuclear weapons after its spent?
Anastasy [175]
Most of it – about 96% – is uranium, of which less than 1% is the fissile U-235 (often 0.4-0.8%); and up to 1% is plutonium. Both can be recycled as fresh fuel, saving up to 30% of the natural uranium otherwise required.
