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.

<span>mechanical energy is E=mgh+ 1/2 mV²=2*9.8*1+1/2*2*4.4²=38.96J,
the only force is P, that is a conservative force so the answer is
</span>mechanical energy is conserved and its value is <span>38.96J, </span>
Answer:
distance
Explanation:
as speed is distance by time
You can describe kinetic energy and the potential energy of motion to get your answer.
Answer:
Newton passed sunlight through a glass prism to separate the colors into a rainbow spectrum. He then passed sunlight through a second glass prism and combined the two rainbows. The combination produced white light. His simple experiment proved conclusively that white light is a mixture of colors.
