Question 2 of 4
2. Question
The diagram shows the cross section of a lake. Find the pressure at the bottom of the lake
in unit of Pascal. (Density of water = 1000kg/m3; Atmospheric pressure = 100,000Pa.)CorrectIncorrect -
Question 3 of 4
3. Question
The height of mercury in a barometer is 76 cmHg. If the mercury is replaced by water, find
the height of the water column under the same pressure.
(Density of water = 1000 kg/m3; Density of mercury = 13,600 kg/m3)CorrectIncorrect -
