Answer:
B.3 m/s
Explanation:
We are given that
Wavelength deep water wave=30 m
Time period=T=10 s
We have to find the velocity of deep water wave.
We know that the frequency=[tex]\nu=\frac{1}{T}[/tex]
[tex]\nu=\frac{1}{10}=0.1 Hz[/tex]
Velocity, V=[tex]wavelength\times frequency[/tex]
Substitute the values in the formula
Then, we get
Velocity of deep water wave=[tex]30\times 0.1=3 m/s[/tex]
Hence, the velocity of deep water wave=3 m/s
Option B is true.
