Hi karto, and welcome to Physics Stack Exchange! This is a site for conceptual questions about physics, not general homework help. If you can edit your question to ask about the specific physics concept that is giving you trouble, I'll be happy to reopen it. See our FAQ and homework policy for more information. – David Zaslavsky♦ Sep 9 '12 at 19:00
@DavidZaslavsky: I'm Sorry. This is the second time I'm posting a complete answer. But, Thank you David... For deleting and I didn't know that one about homework. – Ϛѓăʑɏ βµԂԃϔ Sep 10 '12 at 1:00
@CrazyBuddy don't worry about it, just keep an eye out for these kinds of questions in the future and don't post complete answers to them. I think it's safe to say that our homework policy applies to anything in which the OP gives a set of multiple choice answers to choose from. – David Zaslavsky♦ Sep 10 '12 at 1:24

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
