Homework Statement
I have a problem from the 2002 AP exam; The questions specifically are from 3b, c, and d. ( See the attached image.)
Homework Equations
So I'm trying to solve for the unknown density of the liquid (pW). From what I can assume so far, the object is submerged in the liquid, dispersing a volume of water equal to the volume of the object; however, I suppose there will be a different dimension? I believe that the height determined from the object to the surface of the liquid will be essential to this problem?
I believe I am trying to find the weight of the unknown liquid's volume. Would that be the same as the weight of the object?
I think I do not understand some of the concepts at hand, honestly.
The Attempt at a Solution
F=kx
F=Weight
Weight (N)= Fb (Buyant Force)
Density of mass is known; use that to find the volume:
Weight = (Density)(volume)(Gravity acceleration)
W= (p)(v)(g)
Volume of object = Volume of liquid
Fb = pL(v)(g)
