Calculate the orbital velocity and time period of revolution of a satellite orbiting around the earth at a distance of 3,000 km.

Explanation

To solve the problem of calculating the orbital velocity and time period of a satellite orbiting the Earth at a distance of 3000 km, we will follow these steps:

### Step 1: Determine the Total Radius of the Satellite's Orbit
The total radius \( r \) of the satellite's orbit is the sum of the Earth's radius and the altitude of the satellite above the Earth's surface.

- The radius of the Earth \( R_e \) is approximately 6400 km.
- The altitude of the satellite \( h \) is 3000 km.
