HELP! PHYSICS Paper 5 (A-level practical)

[ambitious1]

Hello,
Regarding paper 5, Is there any site with detailed drawings and answers?
Any suggestions to where or what i can get helped with in this paper?
As it isn't included in my theory part that I study from.
Will be really thankful

Assalamoalaikum!!

I'm attaching the Paper 5 Tips!
I'd been struggling with Paper 5 recently! But believe me, I'm alright with it now by Allah's grace!

What I suggest is first read out these tips. Then start solving some questions, the one's you think you can atleast decide, or may be you can understand that situation! Open the mark scheme and the examiner report, refer both of them side-by-side, and write down your answer!

I'm sure, after you've solved a few papers this way, you'll find Paper 5 really easy. That's what happened with me!

Hope this helps! Good luck!!!

would someone give me tips about the first question of physics p5 that i have attached with diagram needed to draw :evil:

 

[ambitious1]

HEY,
PAPER 5, MJ 2007, Q2

Can someone give me the absolute errors in the table? it's not available in the mark scheme, + Q2a, what should be my statement after re-arranging the equation?

Thanks )

is there any website from where i could get detailed diagrams of experiments

Hey guys, can anyone teach me how to find out gradients and y intercepts from given equations, for e.g if the equation given to us was R=T^h/g then how do you determine gradient and y intercept on terms of g and h? The question also mentioned something about plotting lg r on y axis and lg t on x axis.. It's w 11 Q2.. Help please, I'm really struggling with this paper.

 

[musa Khan]

Also, how do we find the error in the value of y intercept of the line of best fit?

In terms of log, it will be..
LogR = (h/g)LogT
And you can compare this to y= mx + c
m(gradient) = h/g
While y-intercept in this case is zero.
And y Is logR and x is logT

 

[iris987]

apply log on both sides i.e lgR =h/g lgT
Compare Y = M X + C
Y=lgR
M=h/g
X=lgt
C=0

Also, how do we find the error in the value of y intercept of the line of best fit?

Error/uncertainty in gradient = gradient of line of best-fit - gradient of worst acceptable line

Error/uncertainty in y-intercept = y-intercept of line if best-fit - y-intercept of worst acceptable line

Please help me with Q1 paper53/MJ/10

 

[musa Khan]

Haha guys thanks but the h was actually in the power and g was being divided by t^h, well I get the question now, can some one please open up w 11 and solve part d (i)? Marking scheme says k= 10^2 * y intercept but shouldn't it just be 10^y? Where did the 2 come from? :/ please help guyssss

anyone tel me how to calculate absolute errors when 2 dimensions multiplied

anyone tel me how to calculate absolute errors when 2 dimensions multiplied

find fractional uncertainity and multiplly by actual value...........for example in Q2 http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_s07_qp_5.pdf
u have to find absolute uncertainity of l ^2
0.4/6 * 2* 36 (for first box)

oh ok thanks. and how did u solve last part of this question?

magnesium can u tel me how to do quest 2 part c in http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_s09_qp_5.pdf

error bars for lg (I/ A)
{delta x + delta x /2} / {delta x - delta x /2} .Take log of this whole term...

Use the formula given.. for the absolute error use values of best fit and worst fit gradient in the formula and subtract them..
