    HAHAHAHAHA, it was the same, but confirm it from your teacher, maybe our answers are wrong, :p see I have the guts, unlike you.

    Loll, are you asking me? :o you are just arguing on a pointless argument. Go ask your teacher now. :p

    What will be f equal to in that case? F was constantly changing? I wonder if you have an answer for that too.

    There's got to be a way, If you say this is wrong, than what do you propose is the correct solution for the question? :O

    Are you really a dumb idiot? :p

    Physics Paper 22 Nov 2013! How was it?

    Well, Well, a wave has only two amplitudes, one that is a crest the other one is a trough. Since displacement from equilibrium is a vector quantity there returning back to the equilibrium position wnt be counted as displacement. Hence it is 40 mm :p even if it's 20 mm Sirf 1 marks ka tha...

    No it wasn't 20mm a wavelength has a crest and a trough only, so it displaces from equilibrium twice only, hence 80mm / 2 not 4.

    How how can air resistance act on a wheel? I think the ans was weight of the wheel and the normal reaction force between the pin and the wheel.

    Ans for q2 was 120m and pq is 0.18m and the wave was transverse and progressive.

    Physics Paper 22 Nov 2013! How was it?

    80 mm was the displacement from equilibrium position hence 40 mm was the amplitude and 1.5 m was given in the question, no idea about the overall a thingy

    If u wrote If u wrote transverse and progressive why did u draw a straight line, it wasn't a stationary wave, the new wave drawn should have been 1/4 of the wavelength towards the right.

    I guess so. Because the force wasn't constant it was changing with the distance.

    Isn't Isn't pq 0.18 m?

    physics 22

    The force wasn't constant throughout the motion, hence we had to take out average force acting on the object, and use the formulae work done = force * distance, for which we get 0.18 m

    Q1 was hell difficult, i expect the GT to be very low. most of the students were worried about their Q1. I myself left 5 marks because of very less time :/
