  • Question 6
    1 / -0

    Use the following information to answer the next question.

    A geostationary satellite revolves around earth in a special orbit (known as the geosynchronous orbit) in such a way that it takes one day to complete one revolution around earth. This satellite revolves around earth with a speed of 3070 m/s.

    What is the approximate radius of the geosynchronous orbit?

  • Question 7
    1 / -0
