In a region where the speed of sound is 330 m/s, a source ofsound emits a frequency of 440Hz. Assuming the observer is notmoving, at what speed would the source have tomove for the observed frequency to be 330Hz? Are they movingtowards or away?
A. Torwards
B. Away
C. This situation is not possible
D. The Observer is at rest
Part 2: Use the setup above. Enter the speed of the source withthe units of m/s, entering only the numerical value without units.If the situation is not possible, enter -1
