4) An object whose specific gravity is 0.850 is placed in water. What percent of the object's total volume is below the surface of the water? Solve mathematically and explain. [Hint: What implicit information about the weight of the object is given by the question?] 5) Explain how a submarine uses Archimedes' principle to submerge and surface without the use of its propeller. How and why does a hot air balloon rise and fall? Even if you don't know the exact mechanisms, you should be able to make some general statements based on an understanding of Archimedes' principle. T
