A barometer to mercuryMESCHENMOSER ARTHUR
The correct Answer is:B When the lift is at rest, the barometer pressure P=ρgh. But when the lift moves down with an acceleration a where altg, the resultant acceleration becomes (g-a) and P=ρh(g−a) Show More | ShareSaveClass...
Submit The height of the mercury column in a barometer at a place is 75 cm. If a liquid of unknown density is used the height of the liquid column is 150 cm, find its density. View Solution Free Ncert Solutions English Medium NCERT Solutions ...
In the case of a mercury barometer, the density difference between the mercury in the tube and the density of the surrounding air is enormous. But, the weight of the atmosphere is high enough to support the column of mercury. In the case of a salt dome, thousands of feet of sediment, ...

Micromanometers are precision instruments which typically measure from very low pressures to 50 mm of mercury (6.7 kilopascals). The barometer is a sp...
a barometer seemed similar enough that it became known as the “mercurial phosphor” that likely inspired Hauksbee’s electrical experiments, which when coupled with a vacuum apparatus nearly led to the invention of the mercury discharge lamp, nearly 200 years early. The more you know.Continue ...
