1) There are three cubes. 1 is plastic (white), 2 is lucite [clear], and 3 is aluminum. The figure below shows what they look like when they are placed in water. a) How would you rank the buoyant force on the three cubes from greatest to least? b) How would you determine the ratio[s)? (Ratio Format = [density of cube 1) : [density of water]) 2) a) Cube 2 sinks in plain water, but oats in salt water that has a high concentration. Based on that, how would you rank the density of plain water, of salt water, and of Lucite (from greatest to least)? b) How would you determine the density of the Lucite cube from its mass and volume? Plain water 3) There are two metal cylinders. They have the same mass, but they are made out of different material with different density a) How would you determine the buoyant force on each by measuring their weight in water and in air? b) How would you measure their dimension and calculate their volume? c) How would you find out their densities
