A) 10 years
B) 32 years
C) 100 years

E) 1,000,000 years

Question

Quizplus · Accepted Answer

The orbital period of a planet can be calculated using the formula P^2 = a^3, where P is the period in years and a is the average distance from the sun in astronomical units. Plugging in the values for Saturn (a=10), we get P^2 = 1000, which means P = √1000 or approximately 32. Therefore, the best choice is B, 32 years.
