Question
An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom. (Note that for Parts a through c, you should assume that the object has settled in equilibrium.) (a) The magnitude of the buoyant force is equal to the weight of fluid displaced by the object. Under what circumstances is this statement true? o for every object submerged partially or completely in a fluid Oonly for an object that floats at the surface o only for an object that sinks to the bottom O for no objects submerged in a fluid (b) The magnitude of the buoyant force equals the weight of the object. Under what circumstances is this statement true? O for every object submerged partially or completely in a fluid O only for an object that floats at the surface O only for an object that sinks to the bottom O for no objects submerged in a fluid (c) The magnitude of the buoyant force is less than the weight of the object. Under what circumstances is this statement true? o for every object submerged partially or completely in a fluid o only for an object that floats at the surface o only for an object that sinks to the bottom O for no objects submerged in a fluid (d) An object is floating in equilibrium on the surface of a liquid. The object is then removed and placed in another container, filled with a more dense liquid. What would you observe? O The object would sink all the way to the bottom. O The object would float submerged more deeply than in the first container. O The object would float submerged less deeply than in the first container. O More than one of these outcomes is possible. (e) An object is floating in equilibrium on the surface of a liquid. The object is then removed and placed in another container, filled with a less dense liquid. What would you observe? O The object would sink all the way to the bottom. O The object would float submerged more deeply than in the first container. O The object would float submerged less deeply than in the first container. O More than one of these outcomes is possible.Explanation / Answer
