Part B: Determining Density by Water Displacement 9. The density of an object can be determined by observing what fraction of the object is submerged when it floats. For example, an object with 60% the density of water will float with 60% of its volume submerged. Go to https://www.explorelearning. com/index_cfm? method=cResource.dspView&resourceID=400 . Note that ball A and ball F have the same volume. Drop each ball into the water tank, and record the amount of water displaced by each one. What fraction of ball A is submerged when it floats? Use this information to determine the density of ball A. 10.Repeat the previous step to determine the density of ball E and ball C. 11.If the uncertainty in these density values is 5% or less, can you identify any possibilities for what these three solids might be? Part C. Archimedes Principle 12. Suppose you have a tiny boat with dimensions 6.0 cm x 7.0 cm x 8.0 cm. The boat itself is light enough that it can be considered weightless. Use Archimedes principle to calculate how much mass this boat can carry without sinking. After you have an answer, go to https://www.explorelearning.com/index cfm? method=cResource.dspView&resourceID=603 and test your calculation
