Answer:
Explanation:
The movement of the Moon in 13.65 days can be determined by considering its period of revolution and the time elapsed.
The period of the Moon's revolution around the Earth is approximately 27.3 days. This means that in 27.3 days, the Moon completes one full revolution around the Earth.
To find the movement of the Moon in 13.65 days, we can divide the given time by the period of revolution.
13.65 days / 27.3 days = 0.5
This means that in 13.65 days, the Moon completes half of its revolution around the Earth.
Since the Moon's orbit is circular with a radius of 400,000 km, its movement in 13.65 days will be halfway around the circle.
Therefore, the correct answer is: 2) 400,000 km
