<span>The correct answer is D) fusion. In fact, nuclear fusion occurs when two (or more) small nuclei combine to form a heavier nucleus. In the process, a large amount of energy is released, according to Einstein's formula </span>

Answer: Negative acceleration
Explanation:
According to the described situation we have two velocities:
-An initial velocity during the first hour:
-A final velocity during the last 200 miles:
As we can see, the final velocity is less than the initial velocity, this means the plane's velocity decreased.
On the other hand, acceleration is defined as <u>the variation of velocity in time:</u>
Since the plane's velocity decreases, the acceleration is negative.
Hence, this situation is an example of negative acceleration.
