A U-tube of base length I filled with same volume of two liquids of densities ρ and 2ρ is moving with an acceleration a on the horizontal plane. If the height difference between the two surfaces fopen to atmosphere) becomes zero, then height h is given by

A faulty barometer contains some air which occupies 9.5 cc. If indicates 740 mm when a correct barometer indicates 750 mm, the volume the air would occupy under standard pressure

A hole is made at the bottom of the tank filled with water (density= 1000 kg/m³). If the total pressure at the botton of the tand is three atmoshphere (1 atmosphere = 10⁵ N/m²), then the velocity of efflux is

Kerosene oil rises up in the wick of a lantern because of

Three liquids of densioties d, 2d and 3d are mixed in equal proportions of weights. The relatice density of the mixture is

 A capillary tube is dipped in a liquid. Let pressure at point A, B and C be p_A' p_B' p_C respectively then

For the arrangement shown in the figure, the force at the bottom of the vessel is

A tank is filled to a height H. The range of water coming out of a hole which is a depth H/4 from the surface of water level is

Two rain drops falling through air have radii in the ratio 1:2. They will have terminal velocity in the ratio

Block A in the figure shown here hangs by a cord from dynamometer (spring balance) D₁ and is submerged in a liquid C contained in beaker B. The mass of beakerr is 1 kg and the mass of liquid is 1.5kg. The readings of dynamometers D₁ and D₂ of block A is pulled up out of the liquid?
