Answer:
For communication to be communicated between you and your cousin who is in Houston,Texas, when a call is made by you, a request is made to the specific phone, and the telephone tower will get the request from the mobile phone. Then a signal is sent via a transmitter underground, by this the satellite communicates with the local receiver in Houston, that is linked to the local tower over there, the tower would request for your cousin's number and connects the two of you, once a link is set.
Explanation:
From the example stated, what is required for such for a far distance, is a communication satellite link.
When a call is made by you, the a connection request is sent to the specified phone.The telephone tower receives the request from The mobile phone. The local tower(Birmingham,Al) is linked to a ground transmitter by the means of a Fiber optical cable.
A signal is sent to satellite via the ground transmitter.The satellite then set's off the local receiver in (Houston,Texas) which on it's end is connected to the local tower there. This tower then ask for your cousin's mobile for a call that will be incoming, a link is set, once he/she receives the call, from there a conversation can be done.
Friction- the external force that acts on objects and causes them to slow down when no other external force acts upon them.
The frequency of the wave is ![1\cdot 10^9 Hz](https://tex.z-dn.net/?f=1%5Ccdot%2010%5E9%20Hz)
Explanation:
The frequency, the wavelength and the speed of a wave are related by the following equation:
![c=f \lambda](https://tex.z-dn.net/?f=c%3Df%20%5Clambda)
where
c is the speed of the wave
f is the frequency
is the wavelength
For the radio wave in this problem,
![\lambda = 0.3 m](https://tex.z-dn.net/?f=%5Clambda%20%3D%200.3%20m)
![c=300,000,000 m/s = 3\cdot 10^8 m/s](https://tex.z-dn.net/?f=c%3D300%2C000%2C000%20m%2Fs%20%3D%203%5Ccdot%2010%5E8%20m%2Fs)
Therefore, the frequency is:
![f=\frac{c}{\lambda}=\frac{3\cdot 10^8}{0.3}=1\cdot 10^9 Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bc%7D%7B%5Clambda%7D%3D%5Cfrac%7B3%5Ccdot%2010%5E8%7D%7B0.3%7D%3D1%5Ccdot%2010%5E9%20Hz)
