Refer to the previous question. The density of the oil is 875 kg/m3 . When the block floats at equilibrium at the interface between water and oil, what fraction of the block's volume is submerged in water?Flag question Initially, a block of wood floats on water with 90% of its volume submerged. A layer of oil is then poured on top of the water to a depth that more than covers the block, as shown. Is the volume of wood submerged in water greater than, less than, or the same as it was before the oil was added? Note that this is a conceptual question, so no calculation is required at this point; in the next part, you will solve it quantitatively. Oil Water
