Answer:
2.83 m
Explanation:
The relationship between frequency and wavelength for an electromagnetic wave is given by

where
 is the wavelength
 is the wavelength
 is the speed of light
 is the speed of light
 is the frequency
 is the frequency
For the FM radio waves in this problem, we have:
 is the minimum frequency, so the maximum wavelength is
 is the minimum frequency, so the maximum wavelength is

The maximum frequency is instead

Therefore, the minimum wavelength is

So, the wavelength at the beginning of the range is 2.83 m.
 
        
             
        
        
        
Answer
The same number of particles in a gas spread further apart than in the liquid or solid states.
Explanation:
The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume. This means the gas is less dense. Density also depends on the material.
