The height of the mercury column in a barometer is found to be 67.0cm at a certain place. What
would be the height of a water barometer at the same place? (Densities of mercury and water
are 1.36x104kg/m3
and 1.0x103kg/m3)
PLEASE HELP I WILL MARK AS BRAINLIEST

Answer:
Height of a mercury column = 67 cm or, 0.67 m
As it is said about a single place so we can assume the pressure to be equal in both the cases of mercury and water.
Pressure in mercury = Pressure in water
= h₁p₁g = h₂p₂g
= (h₁p₁g) / (p₂g) = h₂
= (0.67*13600*9.8) / (1000*9.8) = h₂
= 89297.6/9800 = h₂
= 9.112 m = h₂
So, there will be a 9.112 m or, 911.2 cm of water column needed to measure the same pressure as mercury.
Hope this helps.
