Hi awing_94,

It looks like you're asking for help with homework problems, which is not what the forum is here for. If it is for your science fair project, please post back with your question, hypothesis, and research so we can see the whole picture not just a small piece.

I would bet money the answers to those questions could be found in your textbook or even using google.
