Convert 1 mm of Hg into pascal. Take density of Hg = 13.6 x 10³ kg m^-3 and g = 9.8 m s^-2

At a given place, a mercury barometer records a pressure of 0.70 m of Hg. What would be the height of water column if mercury in barometer is replaced by water ? Take density of mercury to be 13.6 x 10³ kg m^-3

At sea level, the atmospheric pressure is 1.04 x 10⁵ Pa. Assuming g = 10 m s^-2 and density of air to be uniform and equal to 1.3 kg m^-3, find the height of the atmosphere.

Assuming the density of air to be 1.295 kg m^-3, find the fall in barometric height in mm of Hg at a height of 107 m above the sea level. Take density of mercury = 13.6 x 10³ kg m^-3
