B.) ρA > ρB
C.) ρA = ρB
D.) Not enough information

A wooden raft has a mass of 100.0 kg. When empty it floats in water (density of 1000 kg/m3 ) with 40% of its volume submerged. How many students of mass 75 kg each can stand on the raft without it sinking?
Four cubes of the same volume are made of different materials: lead (density 11,300 kg/m3), aluminum (density 2700 kg/m3), wood (density 800 kg/m3), and Styrofoam (density 50 kg/m3). You place the cubes in a large container filled with water. Rank the buoyant forces that the water exerts on the cubes from largest to smallest. Rank from largest to smallest. To rank items as equivalent, overlap them.
A 4.00 cm x 4.00 cm x 4.00 cm cube of density 920 kg/m3 is floating at rest at the top of a beaker of cross sectional area 100 cm2 with 500 mL of water in it. 500 mL of oil of density 900 kg/m3 is added to the top of the beaker, and the cube is observed to float completely submerged, unevenly straddling the boundary between the oil and water. a. Draw a picture showing the beaker, layers of...
A)An object of volume 7.50×10−4m3 and density 1.15×103kg/m3 is completely submerged in a fluid. Calculate the weight of this object. B)Calculate the buoyant force on this object if the fluid is air (density 1.20 kg/m3). C)Calculate the buoyant force on this object if the fluid is water (density 1.00×103kg/m3). D)Calculate the buoyant force on this object if the fluid is glycerin (density 1.26×103kg/m3)
Chapter 14, Problem 041 What fraction of the volume of an iceberg (density 917 kg/m3) would be visible if the iceberg floats in (a) the ocean (salt water, density 1024 kg/m3) and (b) in a river (fresh water, density 1000 kg/m3)? (When salt water freezes to form ice, the salt is excluded. So, an iceberg could provide fresh water to a community.)
3. Archimedes' Principle states that the buoyant force on an object partially or fully submerged in a fluid is equal to the weight of the fluid that the object displaces. For an object of density po floating partly submerged in a fluid of density pf, the buoyant force is given by F P19 SA(y)dy, where g is the acceleration due to gravity and A(y) is the area of a typical cross-section of the object. The weight of the object is...
