  • Question 2
    4 / -1

    A diatomic gas, having Cp = (7/2)R and Cv = (5/2)R, is heated at constant pressure. The ratio dU : dQ : dW

  • Question 3
    4 / -1

    Keeping the momentum unchanged, if the mass of a body is doubled, then its kinetic energy

  • Question 4
    4 / -1

    A body cools down from 50°C to 45°C in 5 minutes and then from 45°C to 40°C in another 8 minutes. The temperature of the surroundings is approximately

  • Question 5
    4 / -1

    Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

    Assertion A : In a central force field, the work done is independent of the path chosen

    Reason R : Every force encountered in mechanics does not have an associated potential energy.

    In the light of the above statements, choose the most appropriate answer from the options given below

  • Question 6
    4 / -1

    The equation of simple harmonic progressive wave is given by y = a sin 2π(bt - сx). The maximum particle velocity will be half the wave velocity, if c =
