Exercise $3-$ Electromagnetic waves $(9$ points$)$

The ISS orbits $420$ km above the earth's surface and transmits sinusoidal electromagnetic waves of frequency $95\mathrm{.}0$ MHz uniformly in all directions, with a power of $30\mathrm{.}0$ kW $.$

$($a$)$ What is the intensity of these waves as they reach a receiver at the surface of the earth directly below the satellite?

$($b$)$ What are the amplitudes of the electric and magnetic fields at the receiver?

$($c$)$ If the receiver has a totally absorbing panel measuring $50\mathrm{.}0$ cm by $30\mathrm{.}0$ cm oriented with its plane perpendicular to the direction the waves travel, what average force do these waves exert on the panel? Is this force large enough to cause significant effects? Answer with explantion in full sentices
