What will be the length of mercury column in a barometer tube when the atmosperic pressure is `75 cm` of mercury and the tube is inclined at an angle of `60^@` with the horizontal direction?

What will be the length of mercury column in a barometer tube, when the atmospheric pressure is 76 cm of mercury and the tube is inclined at an angle of 30 ^(@) with the horizontal direction ?

What will be the length of mercury column in a barometer tube when the atmospheric pressure is x cm of mercury and the tube is inclined at an angle phi with the vertical direction ?

What will happen if water is used in place of mercury in a barometer tube?

Explain how is the height of mercury column in the tube of a simple barometer, a measure of the atmospheric pressure.

Calculate the length of mercury column in a barometer tube which is inclined at an angle of 45^(@) with horizontal direction if the atmospheric pressure is 75 cm of mercury.

Suppose the pressure at the surface of mercury in as barometer tube is P_1 and the pressure at the surface of mercury in the cup is P_2 .

Suppose the pressure at the surface of mercury in as barometer tube is P_1 and the pressure at the surface of mercury in the cup is P_2 .

Suppose the pressure at the surface of mercury in as barometer tube is P_1 and the pressure at the surface of mercury in the cup is P_2 .

A thin tube of uniform cross-section is sealed at both ends. It lies horizontally, the middle 5 cm containing mercury and the two equal end containing air at the same pressure P. When the tube is held at an angle of 60^@ with the vetical direction, the length of the air column above and below the mercury column are 46 cm and 44.5 cm respectively. Calculate the pressure P in centimeters of mercury. (The temperature of the system is kept at 30^@C ).
