Wave speed = (wavelength) x (frequency)
= (1.5 m) x (500 / sec)
= 750 m/s .
Coastal erosion has depleted a large portion of South Louisiana's wetlands along the coastline in swamps and marshes mainly due to storm surges. But other factors also contributed to this erosion.

Answer:
The bullet will have been dropped vertically h= 0.54 meters by the time it hits the target.
Explanation:
d= 100m
V= 300 m/s
g= 9.8 m/s²
d= V*t
t= d/V
t= 0.33 s
h= g*t²/2
h=0.54 m
Pretty sure it’s c because you would just subtract the 3 miles from the 20
