    ok, first count the number of spaces between P and XY, you will find that you will find 3 spaces, each space represents wavelength. t=wavelength/speed and so the answer is C

    first block doesnt require any energy to life so 0 second block requires u to lift it a height of h and so mgh third block requires u to lift it a height of 2h and so 2mgh fourth block requires u to lift it a height of 3h and so 3mgh add them all together to get 6mgh

    only the loop i mean so points on N1 to N2 are in phase and N2 and N3 as well, however points on N1 arent in phase with points on N3.

    answer is D, because only points within the overlap are in phase and so A and C are wrong. also B is wrong because stationary waves have varying amplitudes.

    Physics: Post your doubts here!

    Q. 29 the answer is c, because what causes the difference between pd and emf is always the internal resistance of the cell. B is wrong because it doesn't really make any sense, connecting wires have absolutely no effect on the emf of a cell. Q.1 you have to arrange the momentum formula and ke...
