Homework Statement
A solid metal sphere of volume 1.05 m^3 is lowered to a depth in the ocean where the water pressure is equal to 1.38 x 10^7 N/m^2. The bulk modulus of the metal from which the sphere is made is 9.9 X 10^9 N/m^2
Given: The atmosphereic pressure is 1.013 10^5 Pa.
What is the change in the volume of the sphere? Give in m^3
Homework Equations
The equation is:
[tex]\Delta V = (-1/B)*Pressure*V[/tex]
B= Bulk modulus
V= volume
The Attempt at a Solution
I really just have one question: what does the atmospheric pressure have to do with anything? I know that F/A (which is the original equation) is pressure, but can I just use the water pressure, or do I somehow have to incooperate the atmospheric pressure?
