Bricks Underwater 2
Imagine holding two identical bricks under water. Brick A is just beneath the surface of the water, while brick B is at a greater depth. The buoyant force on each can be calculated with the formula Fb = ρfVdg. None of these change significantly over a reasonable depth so the buoyant force remains constant. But what if this depth difference is enormous, say in the ocean? For each of the variables in this formula (plus the buoyant force itself), estimate if it...
