If the atmospheric possessor at some place is 70.5cm, fall in Pressure with respect to sea level is:
At sea level , the atmospheric pressure is 76 cm of Hg . If air pressure falls by 10mm of Hg per 120m of ascent, what is the hight of a hill where the barometer reads 70 cm of Hg . State the assumption made by you.
Assumption: atmospheric pressure falls linearly with ascent.
