In a U-tube , water and oil are in the left side and right side of the tube respectively. The heights from the bottom for water and oil columns are 15 cm and 20 cm respectively. Then density of oil is

What is the relative density of liquid if the height of the water coloumn and the height of a liquid column in a Hare's apparatus are 20 cm and 40 cm, respectively ?

Water and oil are poured into the two limbs of a U-tube containig mercury. The interface of the mercury and the liquids are at the same height in both limbs. Determine the height of the water column h_(1) if that of the oil h_(2)=20cm . The density of the oil is 0.9 . .

A vessel contains water up to a height of 20 cm and above it an oil up to another 20 cm. The refractive indices of the water and the oil are 1.33 and F30 respectively. Find the apparent depth of the vessel when viewed from above.

A body floats in water with 40% of its volume outside water. When the same body floats in an oil. 60% of its volume remians outside oil. The relative density of oil is

A U-shaped tube open to the air at both ends contains some mercury. A quantity of water is carefully poured into the left arm of the U-shaped tube until the vertical height of the water column is 15.0 cm . (a) What is the gauge pressure at the water mercury interface ? (b) Calculate the vertical distance h from the top of the mercury in the right hand arm of the tube to the top of the water in the left-hand arm. .

A cubical block of wood 10 cm along each side floats at the interface between an oil and water with its lowest surface 2cm below the interface. If the height of oil and water columns are 10 cm each and rho_("oil")=0.8g/"cc", find a the mass of the block, b. the liquid pressure at the lower surface of the block.

Pure water rises in a capillary tube upto a height of 8 cm . If surface tension of water and acceleration due to gravity are 80 dyne/cm and 1000 cm//s^(2) respectively , then the radius of capillary tube will be
