Question

A satellite 595 km above the earth's surface transmits sinusoidal electromagnetic waves of frequency 92.6 MHz uniformly in all directions, with a power of 25.0 kW.

A- What is the intensity of these waves as they reach a receiver at the surface of the earth directly below the satellite? in W/m^2

B- What is the amplitude of the electric field at the receiver? in N/C

C- What is the amplitude of the magnetic field at the receiver? in T

D- If the receiver has a totally absorbing panel measuring 10.0 cm by 45.0 cm oriented with its plane perpendicular to the direction the waves travel, what average force do these waves exert on the panel? in N
