Answer:
Wavelength is the distance between from one crest to another crest or from one trough to another trough. The amplitude is the distance from the midpoint to the crest or trough. Crest is the highest point of the or a wave. Tough is the lowest point of the or a wave. Rest position is the position where it lies on the midpoint line.
Explanation:
I need a diagram to label these parts.
Answer:
786 J
Explanation:
Let g = 9.81 m/s2. The vertical distance that the canon ball must have traveled within 1.65 s is (ignoring air resistance):

So the work done by gravity would be the product of gravity force and the distance it traveled
[tex]E_p = Ph = mgh = 6*9.81*13.35 = 786 J
<em>H</em> is the location of the Japanese nuclear power plant at Fkushima and <em>I</em> is the location of the Ukraine accident in Chernobyl. At the time, Chernobyl was part of the USSR, but that country no longer exists. These meltdowns will leave the area radioactive for many more years.
