Question

Suppose you have an aquarium and you notice that you have a solid plastic decoration and a rock of about the same volume but twice as dense, and both are totally submerged in the water. The buoyant force on the plastic object is about ___________as that on the rock.A) twice as big.B) the same.C) half as big.D) one quarter as big.

Answer 1

Answer:

.B) the same

Explanation:

Based on the information provided within the question it can be said that the buoyant force on the plastic object is about the same as that on the rock. This can be said easily from looking at both objects, since both objects are completely submerged at the bottom then their buoyant force is the same. If one was floating in the middle of the aquarium while the other was still at the bottom then it would be said that one had more buoyant force than the other.
