A block of wood floats in fresh water with forty percent of its volume submerged.
This block floats in oil with 93 percent of its volume submerged.
(a) Find Db, the density of the block.
(b) Find Do, the density of the oil.
Recall that the buoyant force exerted on a floating or submerged object is the density of the liquid times the gravity constant g, times the submerged ...
With good explanations and computations, the problem is solved.
