V/E=F/R+1
error of V/E=((error of F/F)+.05)x(V/E) (he fractional error of R is 5/100)

For e part ii)
V/E=e part i answer
E=1.6
So u can find V

Would love your input on my diagram for may/june 2008. I am no artist, and no it is not a snake eating the glass sheet, it is my micrometer screw guage.. I've completed the paper and marked it and it seems right. If my diagram is approved, I'll scan my answer and put it up here

the drawing is good!!could u pls scan your procedures as well?

How to do question 1?
how are we supposed to change and measure the frequency of AC?

 

[Igcse stuff]

can someone help me with question 1...I don't understand what the markscheme says, can you help answering, explaining and drawing the diagram for it......http://papers.xtremepapers.com/CIE/...nd AS Level/Physics (9702)/9702_w12_qp_53.pdf

Can someone solve this so that lgT is the y axis and lgr is the x axis......T^2 = kr^3

Can someone solve this so that lgT is the y axis and lgr is the x axis......T^2 = kr^3

Hey there.
Steps:
T^2 = kr^3
=> Times both sides by lg.
=> lgT^2 = lgkr^3
=> 2 lgT = lgk + lgr^3
=> 2 lgT = 3 lgr + lgk
=> Divide both sides by 2.
=> lgT = 3/2(lgr) + 1/2 lgk
This is in the form of y = mx + c
Where y = lgT, m = 3/2, x = lgr, c = 1/2 lgk

Rules used from logarithms:

lgAB = lgA + lgB
lgA^x = x lgA

Hope that helped.

may be with use of signal generator.

Thanks a lot ... that really helped

No problem :'D

Thanks a lot ... that really helped

its never in the mark scheme, you dont need to talk about the range of ammeter or voltmeter

thnk u !
awesome wrk!
but i dnt understand ,hw did u calculate d uncertainty?I mean hw did u get "t" and "10" der?

how do u get uncertainty ???? urgent plz reply soon .... !!!!
