A submarine `9(3)/(4)` metres in height is floating on water.If `(1)/(3)` of its height is under water,then what is the height of the submarine visible above water?

A hill, 101(1/3) m in height, has 1/4 th of its height under water. What is the height of the hill visible above the water?

If water is used instead of mercury in a barometer, what will be the height of water column?

A cylinder of height 1m is floating in water at 0^(@)C with 20cm height in air. Now the temperature of water is raised to 4^(@)C , the height of the cylinder in air becomes 21cm. The ratio of density of water at 4^(@)C to that at 0^(@)C is (Consider expansion of the cylinder is negligible)

A cylinder of height 1m is floating in water at 0^@C with 20cm height in air. Now temperature of water is raised to 4^@C , height of cylnder in air becomes 21cm. the ratio of density of water at 4^@C to density of water at 0^@C is - (consider expansion of cylinder is negligible)

A bird is flying 3m above the surface of water. To a fish underwater, the height of the bird from the water surface appears to be

If we use water instead of mercury in a barometer, what will be the height of water?

Water rises upto 10 cm height in a long capillary tube. If this tube is immersed in water so that the height above the water surface is only 8 cm, then
