1. Radio waves are generated by a transmitter and detected by a reciever. The reciever then encodes the radio wave into information to transport into your radio. You may have listened to either AM or FM radio.
2. Cell phones creates up and down sounds with the microphone. The microchip inside the phone turns those up and down sounds into numbers, and sends it off to the cell tower. The cell tower processes those numbers and sends it off to the phone you are trying to call.
3. The television service delivers programming to viewers by relaying information to communications satellites that can be found orbiting the earth. The satellite receiver decodes the programming to the viewer’s TV.
I'm not sure but I think it is A.
Answer:
50 Hz
Explanation:
The frequency of a wave is given by
where
v is the speed of the wave
is the wavelength
In this problem,
v = 60 m/s
So the frequency is
Heat flow occurs when two systems in contact are not at the same temperature.
What is heat flow?
- when two bodies of different temperatures are in contact, heat flow takes place.
- Heat flows till the two bodies in contact achieve equilibrium.
- To achieve equilibrium, heat flows from hotter bodies to colder bodies.
- There is no heat flow after achieving the state of equilibrium because the amount of heat flow from one body to the other is the same.
