One mole of an ideal diatomic gas undergoes a transition from A to B along a path AB as shown in the figure, The change in internal energy of the gas during the transition is :

Consider 3rd orbit of He+ (Helium), using non-relativistic approach, the speed of electron in this orbit will be [given K = 9 × 109 constant, Z = 2 and h (Planck)′s Constant) = 6.6 × 10-34 Js]

A particle of unit mass undergoes one-dimensional motion such that its velocity varies according to v(x) = βx-2nwhere β and n are constants and x is the position of the particle. The acceleraion of the particle as a function of x, is given by :

On observing light from three different stars P, Q and R, it was found that intensity of violet color is maximum in the spectrum of P, the intensity of green colour is maximum in the spectrum of R and the intensity or red colour is maximum in the spectrum of Q. If TP, TQ and TR are the respective absolute temperatures of P, Q and R, then it can be concluded from the above observation that :
