You are making banana bread and the recipe calls for 3/4 cup of vegetable oil and one egg yolk. You measure out your oil in a measuring cup and then just toss the egg yolk into the oil before mixing with the dry ingredients. The egg yolk has a mass of 9.9 grams and floats with 71 % of its volume under the surface of the oil. You also know that the density of the oil is Poil 0.95 cm³ What volume of oil is displaced by the egg yolk? cm3 What is the total volume of the egg yolk? cm³ What is the density of the egg yolk? g cm3 Imagine the egg yolk was floating in a salt-water solution instead (Pwater = 1.04 % .). What percentage of the yolk would be submerged in water? cm³

A wooden raft has dimensions 4.0 m x 2.0 m with height 0.5 m. The density of wood is 0.65 g/cm3.   How much of the raft is submerged in water?    How many people (average mass 70 kg) could the raft support if it becomes 95% submerged

Buoyancy In the buoyancy lab, you find that the buoyant force is equal to 2.50 N. Given that the density of water is 998 kg/m³, find the volume of the object in cm³. You may use g = 9.8 m/s² 256 m³ 2505 cm³ 256 cm³ 0.0256 cm³ 0.2505 cm³
