The largest barometer ever built was an oil-filled barometer constructed in Leicester, England in 1991. At an atmospheric pressure of 1.013\ \times\ 10^5

1.013 × 105Pa, height of the oil column was 12.2 m.

What was the density of the oil used in the barometer?

• a. 330.33 kgm^{-3}

  kgm−3

• b. 846.40 kgm^{-3}

  kgm−3

• c. 830.32 kgm^{-3}

  kgm−3

• d. 231.03 kgm^{-3}

  kgm−3

10. In a car lift, compressed air exerts a force, F₁ on a small piston having a radius of 5.5 cm. This pressure is transmitted to a second piston of radius 20 cm as shown in figure above. The mass of the car is 1250 kg.

Calculate the pressure on the smaller piston F_1.

• a. 6.25 kPa

• b. 61.31 kPa

• c. 97.57 kPa

• d. 306.56 kPa
