The author describes the lunette as "wall-eyed." Wall-eyed is having large bulging or staring eyes, or an eye in which the iris is of a very light gray or whitish color. What other things could you describe as "wall-eyed?"

Answer and Explanation:

As was mentioned in the question, something or someone that is wall-eyed either has bulging eyes, or eyes that show a great amount of white. Having that in mind, we can think of a few things that can be described as wall-eyed. The very first to come to mind are fish. Fish have bulging eyes, as if they were constantly staring. A surprised or scared person can also be described as wall-eyed. He/She will open their eyes wide due to the astonishment felt. Also, just like the author used the expression to describe lunette, we can also apply it to other objects. A large round window reflecting the moonlight, for instance, can be described as wall-eyed. The same goes for a round mirror reflecting a white wall.

the boy's acceleration toward the girl is 2.08 m/s^2.

explanation:

according the newton's third law, the force causing the girl accelerate towards the boy will be me with equal counter-force causing the boy to accelerate towards the girl. these forces will be of equal magnitude and allows us to determine the boy's acceleration:

the boy's acceleration toward the girl is 2.08 m/s^2.
