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:
ionized particles from the sun.
* interactions in radiation belts.
* the friction of the planet in the solar wind
q = +9 10⁵ C
Explanation:
Due to being made up of matter, the planet Earth has a series of positive and negative charges, in general these charges should be balanced and the net charge of the planet should be zero, but there are several phenomena that introduce unbalanced charges, for example:
* ionized particles from the sun.
* interactions in radiation belts.
* the friction of the planet in the solar wind
This creates that the planet has a net electrical load
We can roughly calculate the charge of the planet
E = k q / r²
q = E r² / k
let's calculate
q = 200 (6.37 10⁶)²/9 10⁹
q = +9 10⁵ C
