Ok, so that is what you are going to do:
1-Open your textbook and read it.
2-Go search on internet for what you haven't found
3- If you have some doubts, or if you find answers taht doesn't make sense, or if you find things that you do not fuly understand, come back here, and tell us. THEN we will help.

But we won't do your homework for you.
