(C) The total pressure $P$ at a depth $h$ below the surface of a liquid is given by the formula: $P = P_0 + ho gh$,where $P_0$ is the atmospheric pressure,$ho$ is the density of the liquid,$g$ is the acceleration due to gravity,and $h$ is the depth.Given:Atmospheric pressure $P_0 \approx 1.013 	imes 10^5 \, Pa = 1 \, atm$.Density of water $ho = 1000 \, kg/m^3$.Acceleration due to gravity $g \approx 9.8 \, m/s^2$.Depth $h = 20 \, m$.Calculation:$P = 1.013 	imes 10^5 + (1000 	imes 9.8 	imes 20) \, Pa$$P = 1.013 	imes 10^5 + 1.96 	imes 10^5 \, Pa$$P = 2.973 	imes 10^5 \, Pa$.Since $1 \, atm = 1.013 	imes 10^5 \, Pa$,the pressure in $atm$ is approximately:$P \approx \frac{2.973 	imes 10^5}{1.013 	imes 10^5} \approx 2.93 \, atm$.Rounding to the nearest integer,the pressure is $3 \, atm$.
