Question

Which of these best arranges the planets in the solar system in the increasing order of their period of rotation?

Select one:
a. Jupiter → Uranus → Mars → Mercury
b. Mars → Venus → Earth → Mercury
c. Neptune → Saturn → Jupiter → Uranus
d. Uranus → Jupiter → Neptune → Saturn

Answer 1

a. Jupiter → Uranus → Mars → Mercury

Answer 2

The correct answer is option A, Jupiter → Uranus → Mars → Mercury

Step-by-step explanation:

Time taken by Jupiter to make one rotation = 9h 56m

Time taken by Uranus to make one rotation = 17h 14m

Time taken by Neptune to make one rotation = 16h 6m

Time taken by Mars to make one rotation = 1d 0h 37m

Time taken by Earth to make one rotation = 23 hours, 56 minutes, and 4 seconds

Time taken by Saturn to make one rotation = 0d 10h 42m

Time taken by Venus to make one rotation = 116d 18h 0m

Time taken by Mercuryto make one rotation = 58d 15h 30m

Thus the correct order is option A,

Jupiter (9h 56m)< Uranus(17h 14m)< Mars(1d 0h 37m) <Mercury (58d 15h 30m)
