Answer:
[tex]f=7.09 s^{-1}=7.09 Hz[/tex]
Explanation:
Hello.
In this case, since the frequency of the mechanical way is computed considering its velocity and wavelength in SI units:
[tex]f=\frac{\lambda }{v}[/tex]
We can compute it for a 12.02-m wavelength and 1.70-m/s velocity as shown below:
[tex]f=\frac{12.05m}{1.70m/s}\\ \\f=7.09 s^{-1}=7.09 Hz[/tex]
Which measured in s⁻¹ or Hz.
Best regards.
