Challenge Question #7:
"Why do you think manatee vocalizations are delicate
and high-pitched?"
Why does a 2.4GhZ phone work better and have a longer
range than a 900Mhz phone? The higher the pitch, the
easier it can get through walls and furniture above
the ocean, so it would be the same below. Also, a high
voltage power line has less resitance than one with a
lower voltage which has a higher resistence.
