Homework Statement
Buoyant force. A block of wood floats in
oil with 90.0% of its volume submerged. What
is the density of oil? The density of the block
of wood is 0.67 g/cm3.
Homework Equations
buoyant force = pgV
The Attempt at a Solution
p(oil) V(oil)=p(h20) V(h20)
p(oil)= p(h20) V(h20) / V(oil)
i know that the V(oil) displaced is equal to .9V(h20)
so, p(oil) = .67 V(h20) / .9 V(h20)
do the terms 'V9h20' simply cancel, leaving me with .67/.9? Thanks
