Scientists want to place a 3600.0 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.8 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem: mmars = 6.4191 x 1023 kg rmars = 3.397 x 106 m G = 6.67428 x 10-11 N-m2/kg2
1. What is the force of attraction between Mars and the satellite?
2. What speed should the satellite have to be in a perfectly circular orbit?
3. How much time does it take the satellite to complete one revolution?
When a signal of intensity 3.0kWm-2 is applied at the input of an amplifier of length 10m, the output signal intensity is 36kWm-2. When the input intensity is reduced to 1.0kWm-2 the output is 20kWm-2.
