b) What is the absolute pressure at the bottom of the container?Thank you so much in advance I am not being lazy I have been working on this problem for ages and cannot figure it out!-a)Ps = ρo*g*Do = 700*9.8*.b)Pbabs = Patm + Ps + ρw*g*Dw = 101325 + 2058 + 1000*9.8*.......
A container is filled with water to a depth of 20.0 cm. On top of the water floats a 30.0 cm thick layer of oil with a density of 0.70 X 10^3 kg/m^3.

a) What is the pressure at the surface of the water?
b) What is the absolute pressure at the bottom of the container?

Thank you so much in advance I am not being lazy I have been working on this problem for ages and cannot figure it out!

a) Ps = ρo*g*Do = 700*9.8*.30 = 2058 Pa

b) Pbabs = Patm + Ps + ρw*g*Dw = 101325 + 2058 + 1000*9.8*.20 = 105343 Pa
