The characteristics of the sound waves allow to find the result for the wavelength is:
λ = 34.29 m
The sound wave is a longitudinal traveling wave, where the speed of the wave depends on the air temperature.
v = 
where v₀ is the speed of sound for T = 0ºc v₀ = 331 m / s.
indicate that the temperature is T = 20ºC, let's find the speed of the traveling wave.
v = 331 
v = 342.9 m / s
The speed of sound is related to wavelength and frequency.
v = λ f
λ = 
Let's calculate
λ = 34.29 m
In conclusion using the characteristics of sound waves we can find the result for the wavelength is:
λ = 34.29 m

Answer:
c. They will be shifted toward the red end of the spectrum.
Explanation:
When the absorption or emission lines of a moving object away from from the earth at very high speed then the spectral lines will be shifted toward the red end of the spectrum.This effect can be easily understand by Doppler effect..
So the our option c is correct.
c. They will be shifted toward the red end of the spectrum.
Answer:
A principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
Explanation:
Mass relates to how much space something takes up (size) density relates to weight
Answer:
The value is 
Explanation:
From the question we are told that
The volume of liquid nitrogen is 
The density of nitrogen at gaseous form is 
= The dry air at sea level
Generally the density of nitrogen at liquid form is
And this is mathematically represented as
=> 
Now the density of gaseous nitrogen is
=> 
Given that the mass is constant
=>
