A group of engineers is preparing a satellite to land by moving it 10% closer to Earth in each rotation. Which statement is correct about the rotational inertia of the satellite? O Rotational inertia first decreases and then increases as the satellite is ready to land.

O Rotational inertia decreases proportional to the decrease in the radius of rotation.

O Rotational inertia increases proportional to the decrease in the radius of rotation.

O Rotational inertia does not change because it is conserved
