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. corresponding to the sound emitted by the source at initial position A, the frequency detected by the observer is equal to (speed of sound relative to air is `330(m)/(s)`)

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 ).
