The ratio of output force to the input force is generally the mechanical advantage of the machine.
Answer:
Wavelength, 
Explanation:
It is given that,
Speed of radio waves is 
Frequency of radio waves is f = 101,700,000 Hz
We need to find the wavelength of WFNX’s radio waves. The relation between wavelength, frequency and speed of a wave is given by :

is wavelength

So, the wavelength of WFNX’s radio waves is 2.94 m.
