The mass density of a spherical galaxy varies as K/r over a large distance 'r' from its centre. In that region, a small star is in a circular orbit of radius R. Then the period of revolution, T depends on R as:

Fill in the blanks : The region in a sound wave, with higher pressure and density is called …………. And that with low pressure and density is called ……….. .

A spherically symmetric gravitational system of particles has a mass density rho={(rho_0,for, r,lt,R),(0,for,r,gt,R):} where rho_0 is a constant. A test mass can undergo circular motion under the influence of the gravitational field of particles. Its speed v as a function of distahce r(0ltrltOO) form the centre of the system is represented by

Many plants in the marshy region had upwardly growing roots. They could be better seen during low tide.

Equal volume of two immiscible liquids of densities rho and 2rho are filled in a vessel as shown in the figure. Two small holes are punched at depths h//2 and 3h//2 from the surface of lighter liquid. If v_(1) and v_(2) are the velocities of efflux at these two holes, then v_(1)//v_(2) is
