measured to be 90,000 Pa, and the density of water is 1000 kg/m³.
(a) Determine the differential height h of the mercury column.
(b) If you replace the water with a higher density liquid, does the differ-
ential height of the mercury column increase or decrease?
(c) If you replace the oil with a higher density liquid, does the differential
height of the mercury column increase or decrease?
