Physics · Secondary 3 · Medium · Pressure in liquids

A student uses a mercury barometer to measure atmospheric pressure. The height of the mercury column is

0.74\,\text{m}

. Take the density of mercury as

1.36 \times 10^4\,\text{kg/m}^3

and

g = 10\,\text{m/s}^2

. What is the atmospheric pressure?
