Answer
a) $P=1.9\times 10^4~Pa$
b) The pressure from the blood exerts additional force on blood vessel walls in the brain.
Work Step by Step
a) $h=1.85~m$
$\rho=1060~kg/m^3$
$g=9.8~m/s^2$
$P=\rho g h$
$P=(1060~kg/m^3)(9.8~m/s^2)(1.85~m)=1.9\times10^4~Pa$
b) The pressure from the blood exerts additional force on blood vessel walls in the brain.
