A C-band station has an antenna with a transponder
gain of 54dB.The
transmitter output power is set to 100 W at a frequency of 6.10
GHz.
The signal is received by a satellite at a distance of 37,500 km
through
an antenna with diameter of 6m. The signal is then routed to
a
transponder with a noise bandwidth of 36 MHz, and a gain of
110dB

B) P/(πr2)
C) P/(2πr)
D) P/(r2)
What happens when you put a small ice cube in a thermally
isolated container (like a Thermos) containing considerably greater
volume of hot coffee?

A radio antenna broadcasts a 1.0 MHz radio wave with 29.0 kW of
power. Assume that the radiation is emitted uniformly in all
directions.
What is the wave's intensity 25.0 km from the antenna?
The answer is 3.69×10−6 W/m^2
What is the electric field amplitude at this distance?
