The pressure at the bottom of a jug filled with water does NOT depend on the
pickupchik [31]

Answer:

D) surface area of the water

Explanation:

The pressure at the bottom of a column of fluid is given by Stevino's law:

p=\rho g h

where

p is the pressure at the bottom of the column

\rho is the density

g is the acceleration due to gravity

h is the depth of the liquid

So, we see that the pressure at the bottom of a jug filled with water depends on all these quantities:

A) depth of the liquid

B) acceleration due to gravity

C) density of water

While it does not depend on:

D) surface area of the water
