Two satellites are in orbit around a planet. One satellite has an orbital radius of 8.0×106 m. The period of revolution for this satellite is 1.0×106 s. The other satellite has an orbital radius of 2.0×107 m. What is this satellite’s period of revolution?
5.0×105 s
4.0×106 s
2.5×106 s
1.3×107 s
The illustration below shows a satellite in orbit around a small planet. The satellite’s orbital radius is 6.7×104 km and its speed is 2.0×105 m/s. What is the mass of the planet around which the satellite orbits? (G = 6.67×10−11 N·m2/kg2)
2.5×1018 kg
2.5×1023 kg
4.0×1020 kg
4.0×1028 kg
Two satellites are in orbit around the same planet. Satellite A has a mass of 1.5×10 2 kg, and satellite B has a mass of 4.5×103 kg. The mass of the planet is 6.6×10 24 kg. Both satellites have the same orbital radius of 6.8×106 m. What is the difference in the orbital periods of the satellites?
no difference
