Electrodynamics Let’s consider a small satellite (~1 kg) being pushed to the moon by nothing but radiation pressure on a 30 m2 reflective sail(although not entirely accurate, we’ll forget about gravity and orbital dynamics just to get a feel forthings). Estimate the time it would take for this satellite to travel to the moon. Note that on earth, thetime-averaged flux of electromagnetic energy from the sun is about 0.14 watts/cm2.
I Review I Constants I Periodic Table A radio antenna broadcasts a 1.0 MHz radio wave with 20 kW of power. Assume that the radiation is emitted uniformly in all directions. Part A What is the wave's intensity 35 km from the antenna? Express your answer in watts per meter squared.
A local radio station broadcasts radio waves at 99.7 MHz. Unlike sound, radio waves can pass into outer space, because they are disturbances not in air molecules but in the e-m fields that exist even in the vacuum of space. It's energy traveling independent of matter. a. When that radio wave hits you, how many pulses (wave crests) of em radiation hit you per minute (60 seconds)? (reminder: M = 10 6) b. Radio waves move at the speed of light (c), how far apart is each wave crest (wavelength)? c. If we boosted the signal strength so that station could be heard on the moon, would either the wavelength or frequency change?

A 50 g horizontal metal bar, 15-cm-long, is free to slide up and down between two tall, vertical metal rods that are 15 cm apart. A 5.5×10-2 T magnetic field is directed perpendicular to the plane of the rods. The bar is raised to near the top of the rods, and a 1.2 resistor is connected across the two rods at the top. Then the bar is dropped. Part A What is the terminal speed at which the bar falls? Assume the bar remains horizontal and in contact with the rods at all times.
