Question
Several particles are found on Saturn’s ring. Since the particles collide with each other, scientists want to understand how such collisions transfer energy so as to model the overall structure and composition of the ring. The scientists reveal that after collision, only 50-60% of their energies is retained. The scientists decide to tests substances in the laboratory to identify the particles and to measure the energy remaining after collision. The results of the experiment are shown below;
Based on these results and assuming that whenever two materials are present their remaining energy is averaged, what would the scientist best conclude to be the composition of Saturn's rings? You may use the calculator.

Explanation
The remaining amount of energy is obtained by averaging the remaining energy of any two particles after collision. Therefore, the average for ice and carbon rock is given as;
(83 + 50)/2
=66.5%.
From the statements were told that after collision, these particles lose energy and the energy that remains ranges from 50-60%. Based on this fact, the scientists can conclude that Saturn rings are mostly made up of large amounts of ice and smaller amounts of carbon rocks since the two give an average of 66.5% which is very close to 50-60%. Answer A, B, and D are wrong since their averages are either too large or too small compared to the established average range.
