A cylindrical vessel is filled with mercury and water of equal weights. The total height of the two liquid layers is 29.2 cm. If the specific gravity of mercury is 13.6, then the height of mercury column will be

A vessel is fileld with mercury to a height of 0.9 m . Barometric height is 0.7 m . mercury :

Why is the height of mercury column nearly 76 cm in the tube ?

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

At normal atmospheric pressure the height of the mercury column in barometer is

Water rises a height of 10 cm in a capillary tube. When the same capillary tube is dipped in mercury it falls to a height of 3.4cm. Compare the surface tensions of water and mercury. Assume that the specific gravity of mercury is 13.6, angle of contact of water with glass is 0^(@) and angle of contact of water with glass is 135^(@) .

At higher altitudes the height of mercury column in a barometer will be ____________

The height of mercury which exerts the same pressure as 20 cm of water column, is
