The lenght of te air column in a capillary glass tube closed at one end containig mercury pallet 10 cm long are 43.5 cm and 33.5 cm with the closed end uo and down respectively.The atmospheric pressure is

A uniform tube closed at one end, contains a pallet of mercury 4 cm long. When the tube is kept vertically with closed end upwards, the length of air column between closed end and mercury pallet is 10 cm. the tube is inverted so that open end becomes upwards. find the length of trapped air column (in cm) trapped. take atmospheric pressure 76 cm of Hg.

In given figure, A uniform cylindrical tube closed at one end, contains a pallet of mercury 5cm long. When the tube is kept verticaly with the closed end downward, the length of the air column trapped is 30cm . Now the tube is inverted so that the closed end goes up find the new length of the air column trapped. atmospheric pressure =75cm of mercury. (Assume temperature remains constant in this process)

The length of an air column trapped in a capillary tube by means of a mercury pellet is 5 cm at 30^@ C . If the tube is heated uniformly to 80^@ C , the new length of air column is :

A uniform tube closed at aone end, contains a pellet of mercury 10cm long. When the tube is lept vertically with the closed-end upward, the length of the air column trapped is 20cm. Find the length of the air column trapped when the tube is inverted so that the closed-end goes down. Atmospheric pressure =75cm of mercury.

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 ).

Two tuning forks A and B sounded together give 8 beats per second. With an air resonance tube closed at one end, the two forks give resonances when the two air columns are 32 cm and 33 cm respectively. Calculate the frequenciec of forks.

A vertical tube of length 100 cm contains a mercury pallet of length 5 cm as shown in the figure. The length of the tube above mercury pallet if the tube is inverted is nearly: (atmospheric pressure = 75 cm Hg of Hg)

Water rises to a height of 10 cm in a capillary tube and mercury falls to a depth of 3.42 cm in the same capillary tube. If the density of mercury is 13.6 g//c.c. and the angles of contact for mercury and for water are 135^@ and 0^@ , respectively, the ratio of surface tension for water and mercury is

An open glass tube is immersed in mercury in such a way that a length of 8 cm extends above the mercury level. The open end of the tube is then closed and sealed and the tube is raised vertically up by additional 46 cm. What will be length of the air column above mercury in the tube now? (atmospheric pressure =76 cm of Hg)
