Two life preservers have identical volumes, but one is filled with Styrofoam while the other is filled with sand. When the two life preservers are fully submerged, the buoyant force is greater on the one filled with
A)Styrofoam.
B)sand.
C)same on each as long as their volumes are the same

Question

Quizplus · Accepted Answer

The buoyant force on an object is determined by the volume of fluid it displaces when submerged, according to Archimedes' principle. Since both life preservers have identical volumes and are fully submerged, they displace the same volume of water, resulting in the same buoyant force on each, regardless of their contents.
