Question

why does a solid object that is initially stationary sink in a fluid? multiple choice the weight of the solid object is greater than the weight of the fluid displaced by the object. the mass of the solid object is greater than the weight of the fluid displaced by the object. the volume of the solid object is greater than the volume of the fluid displaced by the object.

Explanation:

According to Archimedes' principle, the buoyant force on an object in a fluid equals the weight of the displaced fluid. If an object sinks, its weight (downward force) is greater than the buoyant force (upward force from displaced fluid's weight). The first option compares the object's weight to the displaced fluid's weight, which is correct. The second compares mass (not force) to weight, and the third's volume comparison is irrelevant to sinking (displaced volume equals object's volume for a fully submerged object).

Answer:

The weight of the solid object is greater than the weight of the fluid displaced by the object.
