What is the angle between the equatorial plane and the orbital plane of $(a)$ a polar satellite? $(b)$ a geostationary satellite?
(N/A) The equatorial plane is the plane passing through the Earth's equator.
$(a)$ $A$ polar satellite orbits the Earth in a plane that passes through the North and South poles. Since this plane is perpendicular to the equatorial plane,the angle between them is $90^{\circ}$.
$(b)$ $A$ geostationary satellite orbits the Earth in the same plane as the Earth's equatorial plane to remain stationary relative to a point on the Earth's surface. Therefore,the angle between the orbital plane of a geostationary satellite and the equatorial plane is $0^{\circ}$.
