AS Physics P1 MCQs Preparation Thread.
may i know what year is this...i got A as an answer is that right?? -
AS Physics P1 MCQs Preparation Thread.
i think it is A the answer because yes work is done when there is pressure in the volume...but he said air resistance is negligible...and all the other options do have work done across them so the only one left is A -

oooohhh u just couldn't imagine how was this question a torture for me...but i finally solved it, see: first when resolving forces...the forces acting down the inclined plane is mg sin(theta)...to get this theta..u will use the opp/hyp=sin(theta), so sin^-1(3/7)=25.4 is the angle needed...then... -

Seriously guys...im feeling that there is no serious consideration about starting with the revision from 2003, if there will be nothing then lets leave any person post his doubts and the others answer!!! -

by the way if we are going to choose 4 ppl from here to help in the explanation of the exams i back SMZIMRAN to be one of the 4 ppl -

Q5:the time period is 0.7cm...do the conversoin of cm and mm and multiply the time base which is 10mscm^-1 do get an answer then the frequeny is 1/this answer and so it is B.. Q9: you must draw a tangent to get the answer Q20: for a rubber band..the force is proportional to the extensoin but at... -

i may have a small idea..starting from tommorow june 4..we start only with june 2003 to june 2005 ..2 years in one day and we continue till we finish...4 qualified ppl from here to be choosen and divide the four exams on them every 1 of them post the explanation for the tough questoins of each... -

yes sry its A im the one who read it wrong, but my answer is correct it is 6.4 x 10^-15....and about the frequency..u see how many complete wavelenght in the graph if the X axis is distance..in Wave P, there is 2 complete wavelength or because the graph is time which is s..so there is 2 complete... -

Q 24: Wave P has half the amplitude but double the frequency..it have a frequency of 2t and amplitude of X0 which gives an intensity of I0....Wave Q have half the frequency and double the amplitude...so 2 times X0^2 is 4I0...and 0.5 times t^2 = 0.25I0...so 4x0.25=1 Io so answer is B Q31: force... -

hey guys when r we going to start the preparation...there is less than 2 weeks left -
how was physics practical 32
thats right,,good luckto all of us...and maybe as one of us here said there is a range of error where the y intercept can be between negative and positive!! -

for Q 18..it is D, you must get the first acceleration using Vsquared=2as...so a=5...then using the same equation you substitute the a and get the distance which is 90 for Q 40..its D he said the up one is 2/3...and the down one is -1/3...if u add them ull get 1/3..so 1 proton - 1/3 = 2/3..so we... -
how was physics practical 32
ok another is that most of the students got it negative and another proof is that the y axis had a very wide range which can tart from 5 to 700 according to the equation (L/2 -d)squared...and by using the equation y=mx+c the y will be negative..but im pretty sure that most of u just lsaw from...
