Two starts `P` and `Q` have slightly different surface temperature `T_(P)` and `T_(Q)` respectively, with `T_(P)gtT_(Q)`. Both starts are receding from the earth with speeds `v_(P)` and `v_(Q)` relative to the earth. The wavelength of light at which they radiate the maximum energy is found to be the same for both.

The p-V diagrams of same mass of a gas are drawn at two different temperatues T_(1) and T_(2) Explain whether T_(1)gtT_(2) or T_(2)gtT_(1).

The ionization potential of hydrogenic ions P and Q are V_(P) and V_(Q) respectively. If V_(Q) lt V_(P) then radii ......

A particle is thrown vertically upwards from the surface of the earth. Let T_(P) be the time taken by the particle to travel from a point P above the earth to its highest point and back to the point P. Similarly, let T_(Q) be the time taken by the particle to travel from another point Q above the earth to its highest point and back to the same in terms of T_(P), T_(Q) and H, is :-

Two satellites P,Q are revolving around the earth in different circular orbits. The velocity of P is twice the velocity of Q . The height of P from the earth's surface is 1600 km . The radius of orbit of Q is (R=6400 km)
