frequency of 8.3GHz. At some point the intensity of the wave was I
= 2.85e^{-25} W/m^{2}.

a) What will be the intensity of the wave three times the distance from the space probe?

b) What is the wavelength of the transmitted signal?

c) If the sun power is
3.88e^{26} W, at what distance form the sun, the radiation
intensity will be 0.263 W/m^{2}?

d) What will be the absorption radiation pressure exerted by the sun on the probe at that distance?

e) If we consider the above distance as the New Horizons distance to earth. And that the power of the antenna is 17 W. What will be the intensity of the wave transmitted by New Horizons that reaches the earth?

electromotive force induced in the loop antenna, assuming that the
transmitted power is evenly distributed in all directions? Far from
the transmitter, the wave can be locally modeled as a planar wave....

A satellite orbits Earth with an orbit radius equal to 4 × 107 m (measured
from the center of the Earth). The satellite transmits electromagnetic waves to
2 × 109 Hz. Assume that the satellite transmits the radiation evenly
in all directions. The intensity of the EM wave received by an antenna
circular on the Earth's surface is 2 × 10-12 W / m2 when the satellite is
located 3 × 107 m above the antenna. The antenna disk has...

a tall tower extending above the trees. The dish points upward and
to the left. Three parallel wavy arrows come come downward and to
the right toward the...

A space probe (mass m) is designed to explore the outer edges of
the solar system. It is propelled by a solar sail, which is made of
a large circular sheet of highly reflective fabric. Assume the sun
