- 8. A piece of copper has a mass of 2.6 kg. a. What is the volume of this piece of copper?b. The copper is then totally submerged in water. What is the buoyant force acting on it? c. What is the piece of copper’s apparent weight in the water?What is true about the volume of displaced fluid for an object that is completely submerged? (1 Point) The volume of displaced fluid is equal to the object's volume. The volume of displaced fluid is less than the object's volume. The volume of displaced fluid is greater than the object's volume. The volume of displaced fluid is not related to the object's volume.ption 4When an object of mass 14.5 kg is submerged in water, a scale reads only 13.4 kg.
