Such a device (filled with mercury) is shown in the figure, measuring the pressure inside a jar of peanuts. The mercury level on the side of the manometer which is open to the air is 7.1 cm lower than on the side connected to the balloon.

Hints remaining: 3 Feedback: 0% deduction per feedback.Explanation / Answer
h = 7.1cm = 0.071 meters
= 13.5g cm^3 = 13 500 kg/m3
g = 9.81 m/s2.
The gause pressure in the jar. P=gh
=0.071 m*9.81 m/s2*13 500 kg/m3= 9402.885 Pa.
gause pressure = 9402.885 Pa.
