Answer:
natural period = 22.341 × 10³ s
not expecting development of tides
Explanation:
given data
average depth = 19.9 meters
length = 156 km = 156000 m
to find out
the natural period of oscillation of Long Island Sound
solution
we know that natural period formula that is
natural period = ................1
here l is length and h is average depth
put here value in equation 1
natural period =
natural period =
natural period = 22.341 × 10³ s
here i think of very long dam expected length 30 to 50 km be built from coasts straight out to sea or ocean without enclosing
tidal phase difference are introduce across the dam
that leads to significant water level differential in shallow coastal sea
but here not expecting development of tides
