Upon its return voyage from a space mission, the spacecraft has a velocity of 25000 km/h at point A, which is 7130 km from the c
enter of the earth. Determine the velocity of the spacecraft when it reaches point B, which is 6625 km from the center of the earth. The trajectory between these two points is outside the effect of the earth’s atmosphere. The radius of the earth is 6371 km, and g = 9.825 m/s2 on the surface of the earth.

Answer:
The correct answer to the following question will be "Period".
Explanation:
The Period seems to be the time deemed necessary for such a perfect cycle of vibration to transfer a particular moment. Because as the amplitude of the wave raises, the wavelength falls.
It is denoted by "T" and its formula will be:
⇒
Where, T = Period
F = Frequency
The other given choices are not related to the given circumstances. So that the above would be the right answer.
