a mercury barometer is defective. it contains some air in the space above the mercury. when an aacurate barometer reads 770mm, the defective one reads 760mm. when the accurate barometer reads 750mm, the defective one reads 742mm.
(a) what is the length of the air column, when the aacurate barometer reads 770mm?
(b) what is the reading of the accurate barometer when the defective one reads 752mm?
assume that the temperature remains constant.
