A test tube filled with water is placed inclined at an angle of `30^@` with horizontal. Pressure at the bottom of the test tube will be.

The radii of two capillary tubes A and B are in the ratio of 3:1. If water rises to a height of 3 cm in tube A, how much it will rise in tube B. If the tube A is inclined at an angle of 30^(@) with the vertical, then what will the position of water in the tube.

A barometer tube reads 75 cm of Hg. If tube is : gradually inclined at an angle of 30^(@) with horizontal, keeping the open end in the mercury container, then find the length of mercury column in the barometer ■ tube

A test tube is filled with some water .A small piece of wax is fixed at the bottom of the test tube and small piece of wax is made to float on the water what happens to the wax at the top and bottom of the test tube if the test tube is heated at the top middle and bottom?

A barometer tube is inclined at an angle of 30^@ with horizontal direction. Calculate length of mercury column in tube if atmospheric pressure is 76 cm of mercury.
