As physics p1 MCQS YEARLY ONLY.
Im really sry...but u r Wrong!!!! 10 is 1 SF and 0.01 is also 1 SF -
As physics p1 MCQS YEARLY ONLY.
for polymeric materials ( ex rubber)....after the elastic limit and before the breaking point, a large increase in the Force cause a small increase in the extension...so A is the graph wich supports this idea..and besides u must know what is the shape of a force-extension graph for each type of... -

Guys didnt we agree that we must upload the explanation of Nov 2009 and june 2010..this is the second day and no one posted anything....i cant work alone i need help!! i know most or all of u are busy studying, but im busy too..and this is not the time to quit on the thread..ive posted Nov 2011... -

NOV 2011 VARIANT 2 1: C....W=QV, so W which is = work done = energy..so C 2: D......basic stuff 3: D......again, basic stuff 4: D.....when we add or subtract numbers..we just add their uncertanities so 0.02 + 0.03 = + or - 0.05 so D 5: B....A is ofcourse wrong, C and D are systematic errors so... -

yes anybody can help here...and thnx, yes they are the same i didnt notice this!! -

I told u I promise..ok, now... Q15: first u need to get the angle theta of the triangle using...opp/hyp=sin ( theta) so 3/7 = sin ( theta) so sin^-1 ( 3/7) = 25.4...then when resolving forces..the force down the inclined plane is mg sin ( theta) so 2 x 9.81 sin ( 25.4) = 8.42...then 8.42 - 5n (... -

im sry i cant at the moment have to go...but i promise i will!! -
AS Physics P1 MCQs Preparation Thread.
no it is C..as the uncertanity must be rounded to 1 SF.....in the question when u see the 2 uncertanities the least one have 1 sf so rounded and ull get 0.4..wish i helped -

thnx very much...between today and tommorwo ill be psting the 3 variants of the Nov 2011 -

As physics p1 MCQS YEARLY ONLY.
For Q 4...he said that there is a systematic uncertanity of 1%..but this question was tricky as there was another 1% uncertanity he didnt say..he wantedus to figure it out..which is when he gave us that the reading fluctuates between 1.98 and 2.02..if u think about it ull find that if it... -

can i please post the Nov 2011 3 variants..i dont have time to resolve from 2010 tojune 11..if u and any 1 who can help u, just post till june 2011 and ill post the 3 variants of Nov 2011 in the next 2 days -
As physics p1 MCQS YEARLY ONLY.
y r u complicating it on urself..he said whatis the minimum force APPLIED TO EACH END OF THE LEVELER..so we multiply by the ditance between the 2 force....and the 0.2 is the ditance from the weight to the pivot so... F x 1.2 = 900 x 0.2 wish u understood this time Q19: the melting point suff is... -

As physics p1 MCQS YEARLY ONLY.
Q13: moment is Fxd = fxd so F x 1.20 = 900 x 0.2 ( 0.20 is the radius given)...so F = 150..by the way i think it is Tkb..he just explained it to me..so all the credit goes for him Q 19: i explained it above but ill try again...here we all know that brittle materials, example glass..when...
