Answer:
The purposes of the two passages are different. The first passage is biographical and contains quotes that reflect Grady's feelings about Reconstruction. The second passage is a personal essay which directly states the author's feelings about Reconstruction.
Explanation:
It follows that: The gravitational force decreased to F.thus, option B is correct.
Twin satellites that were 150 meters apart when they were launched are now 300 meters apart.
The gravitational force is as follows when the satellites are 150 meters apart:
F= g× m1m2/(150m)₂
Similar to this, the gravitational pull is as follows when the satellites are 300 meters apart:
F= g ˣ m1m2/(300m)₂..........(1)
based on eq (1) and (2)
Fe/ F'e= 4...........(2)
F'e= F c/4
As a result, there is a 1/4 reduction in the gravitational attraction between the twin satellites.
Thus, the appropriate choice is (b).
