A tank contains 140 cm height of water at the bottom and an oil of density \(900\,kg\,m^{-3}\) to a height of 200 cm above water. If the liquids are immiscible, then the initial velocity of efflux of water through a small opening at the bottom of the tank is:
A body is thrown vertically upwards from the surface of the earth with a velocity \(K\) times the orbital velocity of a satellite near the surface of the earth. If the maximum height reached by the body is 200% more than the radius of the earth, then the value of \(K^{2}\) is:
A circular disc of radius \(15\,cm\) and mass \(10\,kg\) is suspended by a wire attached to its centre. When the wire is twisted by rotating the disc and released, the period of torsional oscillations of the disc is \(1.5\,s\). The torsional spring constant of the wire is nearly:
If the Poisson's ratio of the material of a wire is 0.35, then the ratio of the longitudinal and volume strains of the wire is:

A tank of height \(5\,m\) is completely filled with water and a cube of side \(1\,cm\) and density \(1.5\,g\,cm^{-3}\) is placed at the bottom of the tank. The work to be done to lift the cube at the bottom to a height of \(15\,m\) above the surface of water is:
A flag on a boat at rest is fluttering in the south-east direction when the wind is blowing at a speed of \(72\) kmph. If the boat starts moving towards south with a speed of \(36\sqrt2\) kmph, then the direction of the flag on the boat is:
Two brass spheres approaching each other with the same speed collide head-on elastically. After collision, if one of the spheres of radius \(R\) comes to rest, then the radius of the other sphere is:
A uniform thin circular disc of mass \(M\) and radius \(R\) is shown in the figure. The moment of inertia of the shaded region about the diameter AB of the disc is:
Two trains A and B are moving in the same direction with velocities \(V_A\) and \(V_B\) respectively and a third train C is moving in opposite direction. If velocity of C with respect to B is twice the velocity of A with respect to B, then velocity of A with respect to C is:
Law of conservation of mass was regarded as another basic conservation law of nature until the advent of:
