Question

I’ve done question a. But can you help me on b and c

Answer 1

Explanation:

b) Diameter of Mercury = 4.88 * 10³ = 4.88 * 1000 = 4880 km

Radius of Mercury = 4880÷ 2 = 2440 km

c) Mass of Jupiter = 1.898 * 10²⁷ = 18.98 * 10²⁶

Mass of Saturn = 5.68 * 10²⁶

Difference = 18.98 * 10²⁶ - 5.68*10²⁶

= (18.98 - 5.68) * 10²⁶

= 13.30 * 10²⁶

= 1.330 * 10²⁷
