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.
