In the figure shown a source of sound of frequency `510 Hz` moves with constant velocity `v_(S) = 20 m//s` in the direction shown. The wind is blowing at a constant velocity `v_(W) = 20 m//s` towards an observer who is at rest at point `B`. The frequency detected by the observer by corresponding to the sound emitted by this source at initial position `A`, will be (speed of sound relative to air `= 330 m//s`).   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/RES_WFPM_PHY_XI_C06_S01_024_Q01.png" width="80%"
