An area where the particles in a medium are spaced close together is called a _____.
2 answers:
Answer : Compression
Explanation :
An area where the particles in a medium are spaced close together is called a compression. In this region the particles are very close to each other.
In the attached figure, the rarefaction and compression is shown very clearly. In rarefaction, the particles of medium are very far apart form each other.
The distance between two consecutive compression and rarefaction is called the wavelength of wave.
So, the compression is the area where the particles are close to each other.

The final velocities of the two people after the snowball is exchanged is:
Explanation:
The given data is as follows.
Length of beam, (L) = 5.50 m
Weight of the beam, () = 332 N
Weight of the Suki, () = 505 N
After crossing the left support of the beam by the suki then at some overhang distance the beam starts o tip. And, this is the maximum distance we need to calculate. Therefore, at the left support we will set up the moment and equate it to zero.
= 0
x =
=
= 0.986 m
Hence, the suki can come (2 - 0.986) m = 1.014 from the end before the beam begins to tip.
Thus, we can conclude that suki can come 1.014 m close to the end before the beam begins to tip.
