B is a trough.
A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.
In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.
Hope this helps!! :)

Answer:
T = 5516.63 seconds
Explanation:
Given that,
The International Space Station is orbiting at an altitude of about 370 km above the earth's surface.
Mass of the Earth,
Radius of Earth,
We need to find the period of the International Space Station's orbit. It is a case of Kepler's third law. Its mathematical form is given by :
R = r + h
So, the period of the International Space Station's orbit is 5516.63 seconds.
Explanation:
Acceleration is the change in speed over a given time period
