I am sorry but I don't know what the answer can be
Answer:
Option (D) By observing illuminated mountain peaks in the dark portion of the moon.
Explanation:
Unlike the traditions at the time of Aristotle which considered that the celestial bodies are spherical and perfectly smooth bodies.
But based on Galileo's observations, the zone that was illuminated in the dark region of the moon near the line that separates the illuminated and the shadowy parts, known as terminator was noticed.
On the breaking of the dawn, as the sunlight hit the top of the lunar mountains it lightens up while the valleys are still dark.
The force applied on the fly and the windshield are equal based on Newton's Law of Action and Reaction. the difference between them is that the fly's body does not have enough mechanical strength to withstand the force but the windshield does.
All we need to do is divide the momentum and weight to find the velocity:
v = m / w
Solve using the values we are given.
v = 952/68 = 14 m/s
Best of Luck!
