Explanation:
Every cycle on a cosine function are marked by the completion of 5 key points when moving along the x-axis:
(5, 0, -5, 0, 5)
This cycle has a frequency of 2, occurring once every second, thus answering our question easily.

Explanation:
The "coefficient of absorption" of a soundproofing material is
the fraction of sound energy that goes into the material, gets
absorbed, doesn't come out, and is never heard again.
So, sample C would be the best choice, because the percentage
of the energy in an incident wave that gets absorbed in this material
is the greatest, and the percentage of the energy that remains in a
reflected wave from this material is the smallest. (Choice-B)
the answer should be 20 seconds
