Assertion : The graph of `PE` and `KE` of a particle is `SHM` with respect to position is a parabola Reason : This because `PE` and `KE` not vary linearly with positionA. If both statement -I and Statement -II are true , and statement-II is the correct explanation of statement -IB. If both statemenrt-I and Statement-II are true but statement-II is not the correct explanation of statement -IC. If statement -I is true but statement -II is false.D. If statement -I is true but statement -II is true

If the cube is slightly pushed downward, then it oscillates simple harmonically with a period ofA. `2pi(rhoL//sigmag)^(1//2)`B. `2pi(sigmaL//rhog)^(1//2)`C. `1//2pi(rhoL//sigmag)^(1//2)`D. `1//2pi(sigmaL//rhog)^(1//2)`
Assertion : If ice on the pole melts, length of the day will shorten. Reason: Ice will flow towards equator and will result in the decrease in moment of inertia of earth resulting in decrease in frequency of rotation of earth.A.
