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 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 x cm of mercury and the tube is inclined at an angle phi with the vertical direction ?

Why is the height of mercury column nearly 76 cm in the 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 .

If the length of the mercury column in a mercury barometer is 76 cm, what is the equivalent height of the water column ?

In given figure, an ideal gas is trapped between a mercury column and the closed end of a uniform vertical tube. The upper end of the tube is open to the atmosphere. Initially the lengths of the mercury column and the trapped air colume are 12 cm and 50cm respectively. when the tube is titted solwly in a vertical plane through an angle of 30^(@) with horizontal then the new length of air colume is (x)/(41)m . Find x . Assuming the temperature to remains constant. (P_(atm) = 76 cm of Hg)
