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.

The correct answer is
<span>Density
In fact, the density of an object is the ratio between its mass m and its volume V:
</span>

<span>if the size of the object changes, its volume V changes as well, therefore the density d must change.</span>
