q2 graph arent error bars tooo small??
i m getting a ridiculuos value for K......I hav chekd many times....this is wat i get 2.05*10^-16 and 4.79*10^-15......now the 2.05 one is using the correct best fit gradient.....bt error is too large.....i hv chekd multiple times bt stillhttp://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w11_qp_52.pdf

2* 0.01 is the uncertainity for t^2t= 0.35 +/- 0.01
can anyone tell me how to calculate the uncertainty in t^2 ? last time I did this I was in AS so i forgot :/
nah man that's wrong. it says 0.007 in the marking scheme. Oct/nov 09 qp52. Q2'2* 0.01 is the uncertainity for t^2
Is it? :Snah man that's wrong. it says 0.007 in the marking scheme. Oct/nov 09 qp52. Q2'
Can someone please help!
I don't get how to calculate the errors when you log something. Like, take these values as an example:
I (current) = 2.6 +/- 0.1 . Calculate log(I) with the absolute errors.
How would you do it?? It came in this paper, Q2b)

yeah it is. but someone told me how to calculate it properly in the other thread i posted . check it out.Is it? :S
npThanks for the quick reply, and help!
2*0.01*0.35=0.007t= 0.35 +/- 0.01

how to do this?How do you do part 2(e) of this paperttp://www.xtremepapers.com/papers/...nd AS Level/Physics (9702)/9702_w11_qp_53.pdf
but after finding the difference ain't we supposed to divide it by 2 to get the absolute uncertainty ??????????????
