Answer:
car is moving away from, so we does not need to move from his position.
Explanation:
given data
initial frequency = 600 Hz
final frequency = 580 Hz
solution
As we know that by the Doppler effect causes we received frequency of any sources
and
when frequency increases that mean you are moving toward the source or that source is moving towards you
and
when frequency decreases it mean you are moving away from source or the source is moving away from you
and here we have given frequency is decreases from 600 Hz to 580 Hz
so car is moving away from, so we does not need to move from his position.
