The cross-section of the two limbs of a U-tube are 3cm^(2)and1cm^(2) respectively. Keeping the tube vertical, some mercury is poured into it. Now 60cm^(3) of water is poured into the wider limb. To what height will the mercury rise in the narrow limb? The density of mercury = 13.6g*cm^(-3) .

The cross-sectional area and length of each arm of a U-tube are 1cm^(2) and 33 cm respectively. Mercury is poured into it up to a height of 6.8 cm in each arm. Now water is poured into one of the arms to fill it completely. If the density of mercury is 13.6g*cm^(-3) , then determine the volume of water poured into it.

A U-tube of uniform cross-section contains some water. When 4cm^(3) of water is poured into it, the water level rises by 1 cm in each arm of the tube. Now if 10cm^(3) of oil is poured through one of the limbs, the water level rises further by 2.2 cm in the other limb. Calculate the density of the oil.

The external and internal diameters of a hollow sphere are 6 cm and 8 cm respectively. The sphere floats completely immersed in a liquid of density 1.2g*cm^(-3) . What is the density of the material of the sphere?

The cross-sectional area of the left limb of a U-tube is one-third of that of its right limb. It contains some mercury. The empty space in the left limb measures to 40 cm. If water is poured to fill it up, then find the rise of the mercury column in the right limb. (Specific gravity of mercury = 13.6)
