    Physics: Post your doubts here!

    it was 5 ms which is =1/4T it was initially at the 1/4th from my diagram so add 1/4 we get 2/4th stage. :)

    i think you need some pictures to help you learn it. does that make anything clear?

    in 1/4 cycle antinode gets from highest point to zero. then in 1/4 it gets to lowest point then in 1/4 it gets to zero. then in 1/4 it gets back to max. so in one T it completes on cycle.

    friction=6π × 6.6 × 10–4 × 1.5 × 10–3 × 3.7=6.9 × 10-5 resultant force = mass * acceleration = weight-friction ma=9.81-6.9× 10-5 mass = rho * volume = 1.5 × 10-5 a=(9.81-6.9× 10-5)/1.5 × 10-5 =4.93 m/s²

    i just cleared that it was pun otherwise you could think that i had tension because of difficulty of all question.

    tension was in almost every question of today's paper :P ( i mean the force tension, and this is a pun )

    everyone is worried about every paper even if it is easy and they are well prepared.

    idk can't say anything now. it was not bad. the good thing is that even if we lose 10 marks we get an A :P i messed question number 6. but corrected it after time was over. idk if my final answer is correct. still i will be getting more than 45/50

    it had to be shown. the answer 2m/s was already given in paper. so he is not revealing the answer.

    the time above the cliff =2* speed when reached at cliff/acceleration speed at the cliff= 10*√17 / 2 = 5√17 speed at bottom = u =? distance = 40 m, acceleration = g = 10 m/s² v²=u²+2as u²=2*10*40-(5√17)²) u=√1225 =35 m/s

    spend more time thinking about the question and less time doing work. always make diagrams, label them for different times writing velocity/acceleration/forces in every case so you don't miss any detail. before attempting the question always think "can be method be wrong because..." and if you...
