A thin tube, sealed at both ends, is `100 cm` long. If lies horizontally, the middle `10 cm` containing mercury and the two equal containing air at standard atmospheric pressure. If the tube is now turned to a vertical position, by what amount will the mercury be displaced ?

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 ).

A thin tube of uniform cross section is sealed at both ends. It lies horizontally, the middle 5cm containing mercury and the parts on its two sides containing air at the same pressure p. when the tube is held at and angle of 60_(@) with the vertical, the length of the air column above and belw the mercury pellet are 46cm and 44.5cm respectively. Calculate the ressure - in centimeters of mercury, The timperature of the system is kept at 30_(@)C .

A glass tube sealed at both ends is 100cm long, It lies horizontally with the middle 10cm containing mercury. The two ends of the tube contain air at 27^(@)C and at a pressure 76cm of mercury. The air column on one side is maintained at 0^(@)C and the other side is maintained at 127^(@)C . Calculate the length of the air column on the cooler side. neglect the changes in the volume of mercury and of the glass.

In the given figure a glass tube lies horizontally with the middle 20cm containing mercury. The two ends of the tube contains air at 27^(@)C and at a pressure 76 cm of mercuy. Now the air column on one side in maintained at 0^(@)C and the other side is maintained at 127^(@)C . Find the new length of the air column on the cooler side. Neglect the changes in the volume of mercury and of the glass.

One metre long tube, closed at both ends, is lying horizontally. A mercurry column of length 0.1 m is filled in its middle and in rest two parts air is filled at atmospheric pressure. What will be the displancement of the mercurry column when the tube is turned to vertical position ? Atmospheric pressure = 0.76 m of Hg.

What is the height of mercury level in a barometer which is set up in a sealed cabin on the moon containing air at our usual atmospheric pressure.
