Please do your own homework.
Welcome to the Wikipedia Help desk. Your question appears to be a homework question. I apologize if this is a misevaluation, but it is our policy here not to do others' homework, but merely to aid them in doing it themselves. Letting someone else do your homework does not help you learn how to solve such problems.
Please attempt to solve the problem yourself first. You can search Wikipedia or search the Web.
If you need help with a specific part of your homework, the Reference desk can help you grasp the concept. Do not ask knowledge questions here, just those about using Wikipedia.
