Passage V

The orbital energy of a satellite depends on the central body (moon or planet) around which the satellite revolves, the altitude of the satellite’s orbit, and the satellite’s mass. Table 1 lists these characteristics for each of 12 different satellites.

A satellite’s orbital period is the time required for a satellite to complete 1 revolution around its central body. Figure 1 shows a satellite’s orbital period as a function of altitude above the Moon, Mars, and Earth.

32. The diagram below (not drawn to scale) shows the radius, R, of a central body; the center-to-center distance, d, between the central body and a satellite; and the satellite’s altitude.

Given the data in Table 1 regarding Satellites 2 and 10, for which satellite would d be greater?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

From the title It can be seen from the pictured=R+altitude; look againTable 1Satellite 2 andSatellite 10，altitudeBoth1400 km. ButEarth than the radius of the Moon Big, soSatellite 10correspondingd is also bigger.
