Question 3(1 mark)SavedThis graph shows the change in pressure with depth below the Earth's surface.Determine the pressure (in GPa) at a depth of 2100 km.50100150200

The density of sea water is 1025 kg m^- 3.  How many times is the pressure at the depth of 3 km under the sea surface greater than the atmospheric pressure? (g = 9.8 ms^-2 )

If pressure at half the depth of a lake is equal to 2/3 pressure at the bottom of the lake, the depth of the lake is? [Take g = 10 m/s2 atmospheric pressure=105N/m2]

Calculate the depth of a well if the pressure at its bottom is 15 times as that at a depth of 3 metres. (Atmospheric pressure is 10 metre of water)

Calculate the partial pressure of nitrogen at 14.5 metres depth of water. Give your answer in atmospheres.

The pressure at what depth in seawater (density 1,025 kg/m3) is equivalent to that at a depth of 10.0 m in fresh water (density 1,000 kg/m3)?
