A faulty barometer tube is `90cm` long and its contains some air above mercury. The reading is 74.5 cm when the true atmospheric pressure `76cm`. What will be the true atmospheric pressure if the reading on this barometer is 74 cm? (H = 10cm of water column)

A faulty barometer tube is 90cm long and its contains some air above mercury. The reading is cm when the true atmospheric pressure 76cm . What will be the true atmospheric pressure if the reading on this barometer is 74 cm? (H = 10cm of water column)

A faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure at the air temperature=1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.

If the atmospheric pressure is 76 cm of Hg at what depth of water the pressure will becomes 2 atmospheres nearly.

A barometer tube contains a mixture of air and saturated water vopour in the space above the mercury column. It reads 70cm when the actual atmospheric pressure is 76cm of mercury. The saturation vapour pressure at roon tempature is1.0 cm of mercury, The tube is now lowered in the reservoir till the space above the mercury cloumn is reduced to half its origina volume. Find the reading of the barometer. Assume that the temperature remains constant.

A barometer accelerating downwards reads 76 cm of Hg. What will be the possible air pressure inside the jar?

A barometer kept in a lift reads 11 cm of mercury, when the lift is stationary. Then the lift starts moving down with an acceleration a, where a lt g. What is the air pressure in the lift, as read by the barometer ?

the height of mercury in a fauilty barometer is 75 cm and the tube above mercury is 10 cm long. The correct barometer reading is 76 cm. when the faulty barometer reads 74 cm, find the true barometer reading .
