D)the ratio of both the feather's and coin's weight to mass is the same.
E)none of the above

Question

Quizplus · Accepted Answer

In a vacuum, the absence of air resistance means that all objects, regardless of their mass, fall at the same rate due to gravity. This is because the acceleration due to gravity is constant for all objects, making the ratio of weight (force of gravity) to mass the same for both the feather and the coin.
