At a given place, a barometer records 70 cm of Hg. If the mercury in the barometer is replaced by water, what would be resulting in reading? (Density of Hg = 13600 kg/m3; Density of water = 1000 kg/m3)
P is the pressure at some point in a liquid. State whether pressure P is a scalar or vector quantity.
How does the liquid pressure on a diver change according to the following condition:
When the driver moves to the greater depth?
