Homework ?

If you need help understanding something, then by all means ask (science section is probably best). By posting the the questins and asking others to do everything for you, it gives the impression that you want to avoid doing homework and people will be less inclined to help.

Have you tried following the 4 steps I suggested in the first reply? What did you get? where did you go wrong? or haven.t you tried yet?

Show that you are making some effort yourself and you will find others are more willing to help in return.

Thank you for your replies. I would like to say that this isnt my homework. God no, i was at school approx 20years ago and its way above my station!! Its a paper my son is having difficulties with and i would like to understand your workings out & how you did it so i can inturn help him understand. The answers are un-important to me but how you got to your answers is much appreciated. Many thanks
