Question

The average distance of Enceladus from Saturn is 238,000 km; the average distance of Titan from Saturn is 1,222,000 km. How much longer does it take Titan to orbit Saturn compared to Enceladus?

Answer 1

Titan takes 11.634 times longer to orbit Saturn as compared to Enceladus.

Step-by-step explanation:

We have been given that the average distance of Enceladus from Saturn is 238,000 km; the average distance of Titan from Saturn is 1,222,000 km.

We will use Kepler's Law to solve our given problem.

`((T_1)^2)/((T_2)^2)=((r_1)^3)/((r_2)^3)`

Upon substituting our given values, we will get:

`((T_1)^2)/((T_2)^2)=((238,000)^3)/((1,222,000)^3)`

`((T_1)^2)/((T_2)^2)=(13481272000000000)/(1824793048000000000)`

`((T_1)^2)/((T_2)^2)=(13481272)/(1824793048)`

`((T_1)^2)/((T_2)^2)=0.0073878361246365`

Taking square root of both sides, we will get:

`(T_1)/(T_2)=√(0.0073878361246365)`

`(T_1)/(T_2)=0.0859525225030452495`

`(T_2)/(T_1)=(1)/(0.0859525225030452495)`

`(T_2)/(T_1)=11.634329870476699\approx 11.634`

`T_2=11.634\cdot T_1`

This implies that time period of Titan about Sturn is 11.634 times more compared to time period of Enceladus about Saturn.

So, basically Titan takes 11.634 times longer to orbit Saturn as compared to Enceladus.
