To solve this problem we will apply the concepts related to Orbital Speed as a function of the universal gravitational constant, the mass of the planet and the orbital distance of the satellite. From finding the velocity it will be possible to calculate the period of the body and finally the gravitational force acting on the satellite.
PART A)

Here,
M = Mass of Earth
R = Distance from center to the satellite
Replacing with our values we have,



PART B) The period of satellite is given as,




PART C) The gravitational force on the satellite is given by,

Voltage = (current) x (resistance)
Voltage = (0.3 A) x (25 ohms)
Voltage = (0.3 x 25) (A-Ω)
<em>Voltage = 7.5 volts</em>
Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modeling them as vibrations of tiny supersymmetric strings.
Answer:
In a two particle system, the center of mass lies on the center of the line joining the two particles.
