Answer:
Distance Mass 1 Mass 2 Force
10 m 10 kg 15 kg 1.0 × 10-10 N
10 m 15 kg 15 kg 1.5 × 10-10 N
10 m 10 kg 30 kg 2.0 × 10-10 N
10 m 20 kg 20 kg 2.7 × 10-10 N
10 m 20 kg 30 kg 4.0 × 10-10 N
Explanation:
Since Zach concluded that the gravitational force between two objects is directly proportional to the masses of the objects, data supporting this conclusion should include measurements of the masses of the objects and the force between them. Furthermore, data should only show changes in the masses. All other factors should remain constant.
Zach should have used the following data to support his conclusion.
Distance Mass 1 Mass 2 Force
10 m 10 kg 15 kg 1.0 × 10-10 N
10 m 15 kg 15 kg 1.5 × 10-10 N
10 m 10 kg 30 kg 2.0 × 10-10 N
10 m 20 kg 20 kg 2.7 × 10-10 N
10 m 20 kg 30 kg 4.0 × 10-10 N
