    Physics P2 Help Required

    Thanks, in my post when I said "change in a quantity" like Volume, Length, etc I did indeed mean the uncertainty. If you see my post it's almost alike, but I guess I was doing some mistake during the algebric manipulation. Now since I've made R the subject of the formula as you had advised, I...

    So you should have mentioned that in your post! It will only take you 1 second to say sorry, I forgot or whatever pathetic reason you will give, but the time and effort he has wasted will not come back! Anyways, have some decency and try to use your brain just a little bit next time to mention...

    It says "3 Peaks" which includes positive and negative peaks. If you have drawn this correctly, you will get two positive peaks and one negative peak at the center. There are fewer fringes now because the rays will fall on a smaller area now. It's like when you have a flash light and you aim it...

    I just don't know what the issue is with calculating the uncertainties in the measurement questions! I always get it wrong! For example check out Oct/Nov 2007 Q1 (b) Here is my working, please tell me where I am making a mistake! Calculating Radius V = pi R^2 L 15 = pi (R^2) (20) R = 0.489...

    I'm still so confused about this question! I've tried it many times but I always make some mistake. Firstly please tell me, for these kind of questions, what's best, to leave it in diameter form or to change it into radius? Next can you kindly solve this question again with details about each...
