There is a picture of a brick lying face down and one standing straight up. The question asks: Is each brick exerting the same force? Explain.

I know that they are exerting the same force, but I don't understand why and how to explain it?

Why don't you post this under a physics banner? This is more a physics question than a chemistry question. I would answer that F = m*a. Since m is the same and a is the same (it isn't moving) then F must be the same. But I would feel better if you got your answer from someone not pulling answers out of a hat.
Well I'm in Chemistry that's why I put it under that :/
