Answer:
5.5 × 10-2 hertz
Explanation:
The time taken by a wave crest to travel a distance equal to the length of wave is known as wave period.
= 0.055 per second (1 cycle per second = 1 Hertz)
Thus, we can conclude that the frequency of the wave is 5.5 X 10^{-2} hertz.

I think it’s the last one it’s weight divided by its contact area
The component of force which is parallel to the
path of the motion is 10N * cos25 = 9.06 N <span>
This component is the only "effective" force, and
it is the one doing work.
Work = force * distance </span>
Work = 9.06 N * 30 m
<span>Work = 2.7×10^2 J</span>
Answer:
10 Mil. J
Explanation:
multiplyed balls and divided by 5
