A narrow uniform glass tube contains air enclosed by 15 cm long thread of mercury. When the tube is vertical with open end uppermost, the air column is 30 cm long. When the tube is inverted, the length of air column becomes 45 cm. Calculate the atmospheric pressure.

If above tube is held vertical with open end upward then find the length of air column (in cm).

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)

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.

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.

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.
