If the column of mercury in a barometer stands at 73.6 cm, what is the atmospheric pressure? (The density of mercury is 13.6 × 103 kg/m3 and g = 9.80 m/s2)
Thank you for the opportunity to help you with your question!
Pressure = density X g X height
so, P = (13.6X10^2) * (9.80) * (73.6/100) ...............height is divided by 100 to convert it into meters from cm
P = 98.094 x 10^3
Answer is option d.
