The frequency corresponding to the lower cut-off point is
The speed of sound at a temperature of
is approximately
Therefore we can use the relationship between speed of a wave, frequency and wavelength to calculate the corresponding wavelength:
So, the corresponding wavelength is 22.87 m.
Answer:
Explanation:
Given
radius of satellite orbit 
And orbital velocity is given by
where M=mass of earth 
centripetal acceleration is given
For Model airplane
Answer:
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to solid.
Explanation:
Confirmed through test.
The gravitational field strength on the moon is 
of the gravitational field strength on the earth
<u>On the earth:</u>
the gravitational field strength (g) is determined as:
where:
- G: the gravitational constant
- m: the mass of the earth
- r: the radius of the earth
<u>Then on the moon:</u>
![g=[tex]\frac{1}{6}](https://tex.z-dn.net/?f=g%3D%5Btex%5D%5Cfrac%7B1%7D%7B6%7D)
*9.8=1.6 N/kg[/tex]
<u>The answer will be</u> : A.1.6 N/kg
