QUESTION:
Rhea, one of Saturn’s m ns, has a radius of 765 km and an acceleration due to gravity of 0.278 m/s2 at its surface. Calculate its mass and average density.
ANSWER:Solution 14E Mass and average density of the Saturn’s moon Rhea whose radius is 765 km (765000 m) and acceleration due to gravity is 0.278 m/s can be calculated using the relations as follows. Step 1 of 2 Mass is related to radius(R) ,acceleration due to gravity(g) and Gravitational constant(G) by 2 gR M = G 0.278×(765000) 2 = 11 6.67×10 = 2.44 × 101 kg
