What would happen to two objects of different masses that are dropped in a
free fall where there is no air friction or any other forces besides gravity?
A. They would fall with an acceleration of 8.9 m/s2.
B. They would hit the ground at the same time.
C. The heavier object would hit the ground first.
D. Both objects would float away.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
