While sitting on the surface of the Earth, a satellite has a weight of 1600 N. This satellite is put into orbit so that it is four times the distance from the center of the Earth as it had been while on the surface of the Earth. What will happen to the weight of the satellite? A. The weight of the satellite will be reduced to 1/2 of its original, making it weigh 800 N. B. The weight of the satellite...

Problem 1 a. The apogee and perigee altitude (distance from the surface of Earth) of the Chandra X-rays Observatory are 139,200 km and 9,620 km (final orbit after 4th burn, Aug 7, 1999). Estimate its orbital period (in hours). Hint: the mass of Chandra is much smaller than the mass of Earth. b. Communications and weather satellites are often placed in geosynchronous “parking” orbits above Earth. These are the orbits where satellites can remain fixed above a specific point on...

8. Two points A and B located on the surface of the earth are 500km apart. Point A communicates by wireless with point B. Signal from A can travel to B by skywave propagating upward with light velocity c (3 x 103km/s) and reflected down by the ionosphere located 100km above ground, or by ground wave travelling along the ground surface with velocity which is 5% slower than c. What is the time interval between the arrivals of the two...
