    Answer:

    The correct options are (a) and (d)

    a. A satellite’s motion is independent of its mass.

    d. The launch speed of a satellite determines the shape of its orbit around Earth

    Explanation:

    The velocity of the satellite is given by the equation

    v = √(GM)/R

    Where G is gravitational constant, M is the mass of the target planet and R is the orbital radius.

    Therefore, we can conclude that the motion of satellite doesn’t depend on its mass.

    The gravitational force doesn’t change the speed of a satellite so it means that the initial velocity of the satellite will determine the orbital path of the satellite.

    A geosynchronous satellite has a period of 1 day.
