Question

A 50 cm thick layer of oil floats on 120 cm of water. Find the pressure at the bottom surface of water.​

Answer 1

Answer:

Explanation:

pressure = weight/area

weight = mass * acceleration due to gravity

this means pressure = m*g/area

now mass can be broken down as a product of density and volume.

pressure = density* height*g

Density of water = 1000kg/$m^{3}$

acceleration due to gravity = 9.8m/$sec^{2}$

pressure = 1176 pa.
