It appears a lot of your questions come off as homework. If you take a look at our rules, it states this:
"Do not expect LQ members to do your homework - you will learn much more by doing it yourself."
I hope you respect this and you should really try to search for such obvious answers and solutions before asking for direct answers. You shouldn't rely on others to do your work for you as that will get you no where in school, life and so on..
