In a vacuum where there is no air resistance, both objects will fall at the same rate due to the acceleration of gravity. Therefore, the outcome will be as follows:
- The velocity of the objects will become the same as they fall, given enough time.
- The upward push of air resistance will not be applicable since there is no air resistance in this scenario.
- The gravitational attraction between the Earth and the objects will be the same for both since it depends only on their mass and the mass of the Earth.
- The time it takes for them to fall will also be the same as they are dropped from the same height.
Thus, the correct response to which value will be different is: None of the values will be different if there is no air resistance. However, if the question is specifically asking about differences in a vacuum context, the correct answer would be "none", since all values would be the same in that ideal condition. If you are looking for the differences in a general air-resistance scenario, the initial upward push of air resistance would be different in a no-resistance scenario versus a scenario where air resistance applies.
