Precious gems would be my best guess, it's the only natural rescource that's only in one area. Sooo.... Precious gems i guess
It's about the study of the earth. Like mapping, or just looking at different biomes or landscapes.
Answer:
velocity = 7.30 m/sec
23 m depth wave will feel bottom
Explanation:
given data
wavelength = 46 meters
wave period = 6.3 second
to find out
velocity and At what water depth will a deep water wave begin to feel bottom
solution
we get here velocity that is express as
velocity = 
.............1
velocity = 
velocity = 7.30 m/sec
and
wave base = 
× wavelength .................2
wave base = × 46
wave base = 23 m
here water depth more than 23 m will producer will circular wave less than elliptical wave
so 23 m depth wave will feel bottom
