1. Yes, now I understand d= t x s so .124 = -10 x something. or .0124 hours or 44.64 seconds. Cool thanks
2. The other one would be V[SIZE="2"]shopper = d x 20 seconds correct? But if you did that the velocity of the shopper is 0 (she is not moving) so distance has to equal zero which is not...

What Kummer said was correct about the absolute value of two. You can't just cancel it out, you may cancel it out though if it is (square root of x)^2 as long as the radical symbol is inside the parentheses then you may cancel out.
The identities are the things like sec^2x equals 1+Tan^2x, etc. the basic ones.
As for the original form, that's what I'm trying to figure out. I think I have to put the problem in terms of Sin and Cos to simplify it. I'm hoping that's the answer at least.
Jumping off what mgb phys was saying the energized particles move faster and like previously stated have a better chance of hitting off the walls and other particles more often. This energy came from the heat increase and therefore the heat increase would increase the frequency.
Unless another...
If an answer is still needed, leaning things such as oil and nuclear power plants uses many chemicals. Oil refineries are a great example of this as they go through about 10 chemicals on average to be cleaned.
