Question

A source and an observer move away from each other with a velocity of 10 m/s with respect to ground. If the observer finds the frequency of sound coming from the source as 1950 Hz , then actual frequency of the source is (velocity of sound in air = 340 m/s )

Answer 1

Explanation:

1950=n ×((340-10)÷(340+10))=(330÷350)×n

n=1950×350÷330=2068 approx...

so ur ans should be around 2068

hope it helps.....

plz plz mark as brainliest ....if ur a good and kind person.... plz plz it means a lot......
