Is it 3x?How do we go about this?? Can someone please guide me?View attachment 12940
go to page 79 of this thread and ull find me explaining the whole NOv 2011 P1 variant 1 and 2..and ull find that i explained this question with details that will help u alotA trolley runs from P to QAt P, the kinetic energy of the trolley is 5kJ. Between P and Q, the work the trolley does against
friction is 10kJ.
What is the kinetic energy of the trolley at Q?
A 35kJ B 45kJ C 55kJ D 65kJ
plzzz help guys!
no its B π/2radIs it A...π/4 rad ???
oh sry i mis-calculated..yes i got it π/2rad..see first u get the wavelength which is V/F= lamba..so 300/540 = 0.68 so if the length is 0.17..so 0.68 lambda = 0.17m so lambda = 0.17 / 0.68 = 0.25 is the difference between the wavelength..so if lambda/2 = π..then lambda/4 = π/2 so B...hope i helpedno its B π/2rad
yeah, how do we do this??Is it 3x?
see as you throw the ball downwards the G.P.E converts into K.Eyeah, how do we do this??
fr this 1 find the force so it will be F(frictional force)+200sin30=250http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w10_qp_12.pdf
What's the solution to mcq#14 please? Answer is D.
u can solve this with the help of trigonometric ratiosany one pls tell me how to solve q17 is C
ans is b.becz the total energy will be 55 as u missed 1 inf that the ep is 45.so 55-10=45A trolley runs from P to QAt P, the kinetic energy of the trolley is 5kJ. Between P and Q, the work the trolley does against

plzzz help guys!
when two values are added or sbtracted, then the uncertainties are always added so 0.02+0.03= 0.05PLEASE SOME HELP!! I really need to find out whether I am wrong or not!!!! In this the answer is D, and i get it how they got the answer(.03 +.02), but isnt the uncertainty (.03+.02)/(16.24-12.78)View attachment 12946
they so told to find the uncertainity so add o.3+0.2=0.5 so the ans is dPLEASE SOME HELP!! I really need to find out whether I am wrong or not!!!! In this the answer is D, and i get it how they got the answer(.03 +.02), but isnt the uncertainty (.03+.02)/(16.24-12.78)View attachment 12946
it is already solved.check the mcq yearly thread
