As the salt solution increases its salinity, its refractive index also increases, with decreasing temperature. Through this relationship, the refractive index of salt solution at a constant temperature can be used to determine the concentration of the said solution.
Acceleration of anything free falling would increase up to a point where it is at the fastest pace it can go. From then on, its constant. So the answer is constant
Let us assume that the density of seawater is similar to
ordinary water that is:
density ρ = 1000 kg / m^3
Then we can calculate the hydraulic pressure using the
formula:
P = ρ g h
P = (1000 kg / m^3) * 9.81 m/s^2 * 9,500 m
<span>P = 93,195,000 Pascal</span>
