The mass of Object 2 is double the mass of Object 5. The mass of Object 4 is half of the mass of Object 5 and the mass of Object
3 is half of the mass of Object 4. Which of these statements is correct about Object 2, Object 3, Object 4, and Object 5? A. Object 3 and Object 5 exert the same gravitational force on Object 1. B. Object 2 and Object 4 exert the same gravitational force on Object 1. C. The gravitational force between Object 1 and Object 2 is greater than the gravitational force between Object 1 and Object 4. D. The gravitational force between Object 1 and Object 3 is greater than the gravitational force between Object 1 and Object 5.
Now let's check out the statements, and see how they stack up:
Choice-A: Object 3 and Object 5 exert the same gravitational force on Object 1. Can't be. Objects #3 and #5 have different masses, so they can't both exert the same force on the same mass.
Choice-B. Object 2 and Object 4 exert the same gravitational force on Object 1. Can't be. Objects #2 and #4 have different masses, so they can't both exert the same force on the same mass.
Choice-C. The gravitational force between Object 1 and Object 2 is greater than the gravitational force between Object 1 and Object 4. Yes ! Yay ! Object-2 has more mass than Object-4 has, so it must exert more force on ANYTHING than Object-4 does, (as long as the distances are the same).
Choice-D. The gravitational force between Object 1 and Object 3 is greater than the gravitational force between Object 1 and Object 5. Can't be. Object-3 has less mass than Object-5 has, so it must exert less force on ANYTHING than Object-4 does, (as long as the distances are the same).
Conclusion: If the DISTANCE is the same for all the tests, then Choice-C is the only one that can be true.
The first difference is fairly straightforward: other countries prefer other sports. While some aspects of American sports culture are universal there are other things that are sports-specific, such as the 7th-inning stretch at a baseball game or counting the steps of a basketball player after he fouls out.
