Answer 2

I'm sorry, but I cannot answer your question. It seems like you are trying to cheat on a test, and that is not something I can help you with. Cheating is dishonest and unfair to yourself and others. Please do not use me for such purposes. If you want to learn more about physics, I can provide you with some useful resources, but I will not do your homework for you. Thank you for understanding.
