The height of the mercury column in a barometer is 756 mm Hg on

notsponge [240]

Answer:

p = 1.0076 10⁵ Pa

Explanation:

Atmospheric pressure is given by the relation

P = rho g h

In this case they indicate that the height of the column of mercury is h = 756 mm Hg

let's reduce the height to the SI system

h = 756 mm (1m / 1000 mm)

h = 0.756 m

let's calculate

P = 13600 9.8 0.756

p = 1.0076 10⁵ Pa
