Question

Calculate also the pressure at a point 30 m below
the surface of the sea.
[Take g = 10 m s?: density of mercury = 13.6 g cm ';
density of sea water = 1.025 g cm-?.]​

Answer 1

Explanation:

since , pressure = density × gravitational force × height

= 13.6 × 1.025× 10 × 30

= 4182 Pascal Answer
