Answer:
Its because if you put your hands over your mouth it muffles your voice it is because the sound waves can't all go through the material.
Simply put, Potential energy is the "build up". If I had a ball on the top a 5ft slide, it would have potential energy, as long as it hasn't slid down yet.
If I had another ball on a 10ft slide, it would have twice the potential energy the first ball had.
What comes next is kinetic energy, which is the energy used when the object is moving, like the ball as it goes down the slide. The faster it moves, the more kinetic energy.
Basically, <em>Potential</em> is the "build up" but it does not, I repeat does not move.
<em>Kinetic</em> energy is the use of the "build up" through movement.

Sodium Nitrate is written as NaNO(sub3) that is what is throwing you off in this equation.
Take the subscript of 2 off of the sodium in the products and give Sodium Nitrate a coefficient of 2 to balance the equation.
The correct answer would be C. The question asked would be different for a scientist since it has too wide of a focus, as though all situations can be studied at once. Scientists tend to focus or question on one specific area than targeting a lot of topics.
