Answer to Question #245010 in Physics for Diane

Question

A school teacher duplicated Torricelli's barometer using a mineral oil, of density 1,220 kg/m³, as the working liquid. What was the height of the oil column on the day when the atmospheric pressure value was 95,000Pa? State your answer in meters to the nearest thousandth of a meter. Take the value of g to be 9.8m/s² . Do not attempt to enter the unit.

Answer 1

$p=\rho gh\to h=p/(\rho g)=95000/(1220\cdot9.8)=7.946 \ (m)$ . Answer
