The density of gold is 19300 kg/m³ and the denisty of mercury is 13534 kg/m³. Think & Prepare 1. What are the forces acting on the object? Draw a free body diagram showing the forces. 2. What is the relationship between the forces if the object is to float? Volume of liquid mercury displaced for object to float= cm³ Reflect: Can the solid piece of gold in the problem above displace the volume of mercury to float? Can you change the sape of the piece of gold to achieve the necessary buoyant force for gold to float on mercury?

Consider a cube of wood. The cube of wood floats in a fluid so that half of its volume is submerged. What is the Sumbmerged Fraction?
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 4
