    Mathematics Expected GT 2012

    I don't know about M1 and P3 but I think an A in P1 would be around 57-59 and in S1 around 37-39.

    Yes.. the velocity is zero but they are talking about the lowest point of motion, i.e. the lowest position of the mass where it will be going down fast and then slowing to zero speed, not going upwards which is what's happening in B. Look: H . . . E . . . L Let H be the maximum position, E be...

    Weight = upthrust + drag Upthrust is always the smallest force, then it's drag and then weight.

    Where does it say the word energy dissipated per unit time? It doesn't say that in option B. It just says "the ratio of energy dissipated between the points to the current"

    Hmm, yeah you're right. I got this wrong also the first time I did this MCQ because I didn't read the question properly. Thanks for letting me know. :)

    Did you know?

    That's sort of sad... and touching. :| I never throw a chewing gum on the floor though, and every civilized person I know doesn't either. Thanks for sharing.

    So you think you can answer this?

    Bleh. If I was wrong then I don't know. :P Very tricky question indeed.

    So you think you can answer this?

    lol a few other people and I already posted a solution, did you read them? :P Are they valid or not? If my answer is wrong then tax is the right answer. :P

    Nov 2010 P11 Q5 3000 rev/min = 50 rev/sec time period for one rev = 0.02s For the wave to appear on a 10 cm screen, 0.02/10 = 0.002s. Then you will divide by 2 for one pulse to appear = 0.001s or 10 ms/cm.

    November 2009, Q13) We know that at the highest point, Vertical velocity = 0 Horizontal velocity = E cos 45 Resultant = 0² + (E cos 45)² = 0.5E Q25) To solve this question, find the maximum order on one side, multiply that by two and then add the central maximum to find the total number of...

    The wave is undergoing simple harmonic motion. Think of the displacement-time graph as that of a pendulum bob. At the equilibrium position, the particle has maximum velocity and at the maximum displacement position, the particle comes to rest momentarily before changing direction. Since point...
