If, for an earth satellite, the specific angular momentum is 70,000 km2/s and the specific energy is 10 km2/s2, calculate the apogee and perigee altitudes.

The horizontal blue line through the middle of the lens is called the optical axis. as the lamp is moved above or below the axis, keeping the horizontal distance to the center of the lens constant, how does the horizontal distance from the lens to the image change?
