Calculate the depth in the ocean at which the
pressure is three times atmospheric pressure.
Atmospheric pressure is 1.013 x 10° Pa. The
acceleration of gravity is 9.81 m/s2 and the
density of sea water is 1025 kg/m”.
Answer in units of m.

Answer:

Therefore the depth in the ocean at which the presser is three times atmospheric presser is 20.15 m.

Explanation:

The pressure at some depth

[tex]P=P_\circ +\rho gh[/tex]  

[tex]P_\circ=[/tex] atmospheric presser = [tex]1.013\times 10^5[/tex] Pa

[tex]\rho=[/tex] density of the sea [tex]= 1025 kg / m^3[/tex]

g = gravity = 9.81 m/s²

h = depth of the ocean

P= atmospheric presser at depth = [tex]3P_\circ[/tex]

Therefore

[tex]3P_\circ=P_\circ +\rho gh[/tex]

[tex]\Leftrightarrow \rho gh=2P_\circ[/tex]

[tex]\Leftrightarrow h=\frac{2P_\circ}{\rho g}[/tex]

[tex]\Leftrightarrow h=\frac{2 \times 1.013 \times 10^5}{1025 \times 9.81}[/tex]

[tex]\Leftrightarrow h= 20.15[/tex]

Therefore the depth in the ocean at which the presser is three times atmospheric presser is 20.15 m.
