why do you need to solve that old paper ! from 2002 you can solve, which are available on gceguide .hi does anyone have access to physics past paper of 1997 and its ms?

it will be horizontal , it says show error bars for X (it is in x-axis ). for thing like this try to understand rather than remembering things . there is uncertainty in the value of X so we draw error bars to show the maximum or minimum value it can go from the accurate value .9702/w16/51
qtn 2 how to make the error bars
will it be horizontal or vertical as usual....how to do it can anyone plzz show
can someone plzz solve the complete qtn 2
if u remember in AS the wave chapter , for a visible fringe to be seen the wavelength of light should be almost equal to the slit space . so here the electron is replaced with light and the crystal acts like a slit as it has space between them , the space(separation of crystal ) is about the size of wavelength so can be used in electron diffraction.9702_w12_qp_43
qtn 7 b(ii)
can anyone plzz explain me this
The Potential Energy of the ball when it is at A changes to Kinetic Energy as the ball accelerates downwards (It's velocity increases, so KE also increases). After the ball hits the ground, it rebounds upwards with decreasing velocity and increasing height, so KE changes to Potential Energy.Help please?
Need help with question number 2 c (ii) from paper 22 of summer 2012.
I've attached the question.
Would highly appreciate any help. Thanks!
It's not clearly explained. Why doesn't the current flow through Q?

better if you use 5.36VAl Salamou alaikom,
What is the number of Decimal Places to put our answer for VOLTAGE to in Paper 3 Practical when we put the Voltmeter/Multimeter to the 20V setting.
P.S. in the multimter, when we put setting to 20V, it gives us a reading with 2 d.p. i.e. 5.36 V so should we put our answer to 1 or 2 or no d.p.
ZeroView attachment 61960 View attachment 61961 Someone please help me with 6) iv). It's from 41/O/N/11
but why?Zero
Mean voltage so.. xDbut why?
Mean voltage so.. xD
Two ways of doing itCan someone please find the uncertainty in logP when P(20.5+-0.5).Many thanks in advance..
thank you bro....
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
