Nose bleeding occurs at high altitudes because :
- the blood pressure becomes less than the atmospheric pressure
- the blood pressure becomes equal to the atmospheric pressure
- the blood pressure becomes more than the atmospheric pressure
- not related with atmospheric pressure.

Answer
the blood pressure becomes more than the atmospheric pressure
Reason — At high altitude, the atmospheric pressure becomes less. Thus, the blood pressure becomes more than the atmospheric pressure and nose bleeding may occur.

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 76 cm of Hg. If air pressure falls by 10 mm of Hg per 120 m of ascent, what is the height of a hill where the barometer reads 70 cm of Hg. State the assumption made by you.
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
