A satellite is revolving round the earth in circular orbit

An earth satellite is revolving in circular orbit in equatorial plane, It is used for communication purpose. The satellite can transmit signals up to 60" latitude on earth. The angular velocity of satellite is

An artificial satellite (mass m) of a planet (mass M) revolves in a circular orbit whose radius is n times the radius R of thhe planet in the process of motion the satellite experiences a slight resistance due to cosmic dust. Assuming the force of resistance on satellite to depend on velocity as F=av^(2) where 'a' is a constant caculate how long the satellite will stay in the space before it falls onto the planet's surface.

An artificial satelite of the moon revolves in a circular orbit whose radius exceeds the radius of the moon eta times. The process of motion the satelite experiences a slight resistance due to cosmic dust. Assuming the resistance force to depend on the velocity of the satellite as F=alphav^2 , where alpha is a constant, find how long the satellite will stay in orbit until it falls onto the moon's surface.
