Answer:
Titan takes 11.634 times longer to orbit Saturn as compared to Enceladus.
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.
Upon substituting our given values, we will get:
Taking square root of both sides, we will get:
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.

Explanation:
The gravitational force between the asteroid and the ship is given by:
where
is the gravitational constant
is the mass of the asteroid
is the mass of the spaceship
is the distance between the asteroid and the spaceship
Substituting numbers into the equation, we find the force
Aluminium is less dense which is lighter and the cast iron has more dense that's why it's heavier :)
Answer:
Option (c)
Explanation:
The rate of change of linear momentum is called force.
As the linear motion terms are analogous to the terms in rotational motion.
So, the rate of change of angular momentum is called torque.
