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 stan-dard atmospheric pressure. If the tube is now turned to a verical position, by what amount will the mercury be displaced ?

A thin tube sealed at both ends is 90 cm long. It is kept horizontally, the middle 10cm containing mercury and the two equal ends containing air at standard atmospheric pressure. The tube is turned and kept in 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 .
