Sound waves are compression waves, as seen here. the areas of low pressure within a sound wave, area a for example, are called a) amplitudes. b) frequencies. c) rarefactions. d) troughs.

C) Rarefactions is the correct answer.

Sound waves have areas of high and low pressure. The areas of high pressure are called compressions and those of low pressure are called rarefactions.

I hope that helps!

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
