IP A block of wood floats on water. A layer of oil is now poured on top of the water to a depth that more than covers the block, as shown in the figure(Figure 1). If 93 % of the wood is submerged in water before the oil is added, find the fraction submerged when oil with a density of 865 kg/m3 covers the block. Express your answer using two significant figures.
