Satellites use breams of EM waves to communicate with devices on
Earth. Suppose a particular satellite has a power of 18 kW and
sends a focused cone of EM waves toward Earth 4.9x10^2 km away.
When the focused beam reaches the Earth, its circular diameter is
about 1.3 km. What is the peak electric field strength in this
focused beam?

A satellite is to be placed in a circular orbit 10 km above the surface of the moon (Rm = 1.74 * 10^3 km, Mm = 7.35*10^22 kg). 1. What is the orbital speed and period of the satellite? 2. If we could place a satellite in orbit just inches from the Earth's surface, what would its orbital velocity and period be? (Re = 6.37 * 10^3 km and Me = 5.972 * 10^24 kg)

Question 10 One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction. Suppose a satellite in a circular orbit 670 km above Earth's surface collides with a pellet having mass 3.7 g. (a) What is the kinetic energy of the pellet in the reference frame of the satellite just before the collision? (b) What is the ratio of this kinetic energy to...
