- What sensitivity must Earth-based receivers have to receive signals from MRO? Express it as a minimum value for the electric-field amplitude in the radio waves at the receiver, and base your answer on the greatest possible Earth–Mars distance, about 400 million km.Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time. These devices are called pulsed lasers and can be used to ignite nuclear fusion, for example. Consider a pulsed laser that produces an electromagnetic wave with a maximum electric field strength of 1.25×10^11 V/m for a duration of 1.00 ns. What energy does it deliver on a 1.00 mm^2 area?

- Large quantities of dust should have been left behind after the creation of the solar system. Larger dust particles, comparable in size to soot and sand grains, are common. They create shooting stars when they collide with the earth's atmosphere. But very small dust particles are conspicuously absent. Astronomers believe that the very small dust particles have been blown out of the solar system by the sun. By comparing the forces on dust particles, determine the diameter of the smallest dust particles that can remain in the solar system over long periods of time. Assume that the dust particles are spherical, black, and have a density of 2000kg/m^3. The sun emits electromagnetic radiation with a power of 3.9×10^26W.Assuming the energy density of the cosmic background radiation of the Big Bang has the value 3.75 ✕ 10−14 J/m3, what is the corresponding electric field amplitude (in mV/m)?Suppose you have an electric field as a result of superposition of two waves given by Ē(z, t) = Eo cos(kz - wt) + Eo cos(kz + wt)â. a.
