  70

  Half-n-half Clue
 

5.

pressure - manometer
If the density of liquid A (carbon tetrachloride) is 1.6 g cm-3 and its height hA = 11.2 cm, then the density of oil B of height hB = 20 cm in the U-tube is about

  2.84 g cm-3

  1.11 g cm-3

  0.90 g cm-3

  0.35 g cm-3

  Half-n-half Clue
 

6.

pressure - manometer
One arm of a glass U-tube is open to the atmosphere, whereas the other vertical arm is connected to a gas supply. The difference in levels of mercury (density = 13.6 g cm-3) between the vertical arms of the U-tube manometer is h = 2 cm. If the atmospheric pressure is 760 mm Hg and the gravitational acceleration is 9.8 m s-2, then the pressure of the gas is about

  2.666 × 104dynes cm-2

  1.061 × 104dynes cm-2

  1.016 × 107dynes cm-2

  1.040 × 106dynes cm-2

  Half-n-half Clue
 

7.

  may increase or decrease

  remains constant

  decreases

  increases
