What is the buoyancy of an object that is heavier than the fluid it's placed in?

When an object is heavier than the fluid it is placed in, it exhibits positive buoyancy, resulting in sinking. This phenomenon occurs because the weight of the object exceeds the buoyant force acting on it, which is determined by the weight of the fluid displaced by the object. According to Archimedes' principle, if the weight of the displaced fluid is less than the weight of the object, the object will sink. Thus, in this scenario, the correct understanding is that the object will not be supported by the fluid and will therefore move downward.

The options suggesting that the object will float or remain neutrally buoyant would be inaccurate because both situations occur when an object's density is less than or equal to that of the fluid. The option proposing that the object will dissolve does not apply to the context of buoyancy and refers to a chemical or physical change, which isn't influenced directly by buoyancy principles.

Overall, understanding buoyancy requires recognizing the relationship between an object's density and the fluid it is in, which clarifies why an object denser than the fluid will sink.
