When the bell begins to move in the opposite direction, the compressions and rarefactions will be reversed.
A sound wave will be created, as shown below. This type of wave is called a compressional
wave, which is also known as a longitudinal wave.

Pick out all of the numbers that are compressions in the sound wave above, moving from left
to right on the wave. Pick out of all of the numbers that are rarefactions in the sound wave
above, moving from right to left on the wave. This 9-digit number is the combination for the
lock to the next page of this escape activity.

What are some properties of transverse waves?

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
