Answer:
(a) 2440 kg
(b) 1.33 × 10²⁷ kg
Step-by-step explanation:
(a) From the table attached
Diameter of Mercury has been given as
4.88 × 10³≈ 4.88 × 1000 = 4880 km
Since radius of a circle = [tex]\frac{Diameter}{2}[/tex]
Therefore, radius of mercury = [tex]\frac{4880}{2}[/tex]
= 2440 km
The radius of Mercury is 2440 km.
(b) Mass of Jupiter = 1.898 × 10²⁷
Mass of Saturn = 5.68 × 10²⁶
≈ 0.568 × 10²⁷
Difference in the masses of Jupiter and Saturn = 1.898 × 10²⁷ - 0.568 × 10²⁷
= 1.33 × 10²⁷ kg
Difference between the masses of Jupiter and Saturn is 1.33 × 10²⁷ kg.
