Suppose you have an aquarium and you notice that you have a solid plastic decoration and a rock of about the same mass but the decoration is twice as large as the rock. Both are totally submerged in the water. The buoyant force on the plastic object is about ___________as that on the rock.

Respuesta :

Answer:

The buoyant force on the plastic object is about _twice as that on the rock.

Explanation:

The volume of plastic decoration is twice the volume of rock . Buoyant force is equal to weight of displaced volume of water . Since water displaced by plastic decoration is twice , its weight will also be twice . Hence the buoyant force on plastic decoration will also be twice.

The buoyant force on the plastic object is about _twice as that on the rock.
