Answer:
change in frequency is 636 Hz
Explanation:
given data
speed v1 = 36 m/s
speed v2 = 45 m/s
frequency f = 500 Hz
speed of sound s = 343 m/s
to find out
what is the change in frequency
solution
we know here change of frequency formula that is
frequency = 
(f) ...................1
put here value in equation 1
and we take v2 = -45 because opposite direction
frequency = 
(f)
frequency = 
(500)
frequency = 636
so change in frequency is 636 Hz
All components, Abiotic to Biotic
