    we don't do homework for people. post your own answers and we'll see if its right or not and where you need help.
    Its better to learn by understanding than just taking answers

    Welcome to PF, hlo.
    In addition to edmondng's comments, I'd like to point out that not all of us nerds; I mean physicists have access to MSWord all the time. If the question is too large to post in the text, perhaps you could convert your attachment to JPG or PDF (there are free PDF printers for that).

    I'm afraid we scared hlo off, maybe giving the impression that we're not willing to help. That is of course not true, we just expect people to show what they've already tried before coming here (after all, we're not input-homework-output-answers machines). So please don't stop trying and asking questions hlo.
