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 .

The length of a faulty barometer is 90 cm and there is a little air above the mercury. When the atmospheric pressure is 76cm of Hg it reads 74.8 cm. What will be the true atmospheric pressure if the reading on the barometer is 74.3cm ?

A barometer is faulty . When the true barometer reading are 73 cm and 75 cm of Hg , the faulty barometer reads 69 cm and 70 cm respectively (i) What is the total length of the barometer tube? (ii) What is the reading when the faulty barometer reads 69.5 cm? (iii) What is the faulty barometer reading when the true barometer reads 74 cm?

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

A fauly barometer reads 71.12cm and 76.20cm when a true barometer reads 72.39cm and 78.74cm, respectively. Find the ture reading when the faulty barometer stands at 73.66cm.

If the length of the mercury column in a mercury barometer is 76 cm, what is the equivalent height of the water column ?

A mercury barometer is defective. When an accurate barometer reads 770 mn, the defective one reads 760 mn. When the accurate one reads 750 mn, the defective one reads 742 mn. Then The reading of the accurate barometer, when defective are reads 752 mm is
