What would be the weight of 22.0kg dog at the equator on Saturn's surface?
(Saturn's mass equals 5.69 X 10^26kg, Saturn's equatorial radius equals 6.03 X 10^7m, Earths mass equals 5.97 X 10^24)
what number goes into M and d?
Ms is the mass of Saturn, Md is mass of the dog. Are you not familiar with the Law of Gravitation?
d is the distance the dog is from the center of Saturn (ie, radius).
You need to look this up in the text.
Calculate the gravitational force between the Sun and Jupiter. The mass of the Sun is 1.99×1030 kg. The mass of Jupiter is 19000×1023 kg. The distance between them is 77.8×1010 m.
