MULTIPLE CHOICE 1. For a satellite orbiting Earth, the time required to complete a single orbit is known as the period. The period , in hours, is related to the distance , in miles, from the center of Earth by the formula . What happens to the distance as the period increases? A graph of this question. a. b. c. d.
versus
can help you answer
Distance increases as period increases. Distance decreases as period increases. Distance is at a maximum. Concavity changes as the period increases.
