QUESTION $2$

For the same sources in the previous question, rank all the sources from $1-10$ with $1$ being the source moving the fastest speed and $10$ the source moving at the slowest speed. For the rankings, do not distinguish between the different directions of motion, simply rank them based on their speeds.

Source $02$: $f=497Hz$

Source $09$: $f=562Hz$

Source $03$: $f=524Hz$

Source $04$: $f=527Hz$

$7.vv$ Source $05$:$f=532Hz$

$6.vv$ Source $06$:$f=512Hz$

$5.vv$ Source $07$:$f=540Hz$

Source $08$: $f=525Hz$

Source $01$: $f=550Hz$

Source $10$: $f=465Hz$

THE RESTING FREQUENCY IS: $525$Hz$.$
