Question

The New Horizons space probe transmits to Earth at a frequency of 8.3 GHz. At some point the wave intensity 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? If the power of the sun is 3.88e + 26W.

c) At what distance from 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 wave at that distance?

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

f) How many times farther is the New Horizons probe from the beginning of the problem?

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...

The broadcast transmitter transmits a sinusoidal radio signal at
a frequency of 95 MHz with a transmission power of 55 kW. The radio
signal is received at a distance of 2.5 km with a circular wire
antenna with a diameter of 18 cm. What is the maximum possible
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....

1. A space probe is launched from Earth, headed for deep space.
At a distance of 10,000 miles from Earth's center, the
gravitational force on the space probe is 520 pounds. If the
gravitational force acting on the probe is proportional to 1/d2,
what is the force in Newtons when the probe is four times as far
from Earth's center?

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

the sail were three times larger?
2. Jupiter is about five times as far from the sun as the earth.
When the probe reaches jupiter, how...
