Indiana Jones has acquired an artifact called the Amulet of Set, a piece of platinum jewelry in the shape of a snake.  However, he suspects that he has a fake amulet, a replica planted by one of his enemies.  He does not want to risk destroying the amulet in a chemical analysis, so he tries a more ancient method of identification.  He first determines the mass of the amulet as it just hangs from a scale to be 1.28 kg.  When he completely immerses the amulet in pure water, the reading on the scale drops to 1.12 kg.  Draw a diagram showing the forces acting on the amulet as it is immersed. What is the buoyant force felt by the amulet? What is the volume of the amulet?  Do not assume it is actually made of platinum
