What will be the height of mercury column in a barometer it it is taken to the moon?

A satellite revolves round the earth. Air pressure inside the satellite is maintained at 76 cm of mercury. What will be the height of mercury column in a barometer tube 1m long placed inn the satellite?

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 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?

Height of mercury in a barometer is h_0 = 76. 0 cm at a temperature of theta_1 = 20^(@)C . If the actual atmospheric pressure does not change, but the temperature of the air, and hence the temperature of the mercury and the tube rises to theta_(2)= 35^(@)C , what will be the height of mercury column in the barometer now? Coefficient of volume expansion of mercury and coefficient of linear expansion of glass are gamma_(Hg) =1.8xx10^(-4).^(@)C^(-1), alpha_(g)=0.09xx10^(-4).^(@)C^(-1)

Why is mercury taken in a barometer?

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.
