The frequency changes by \( 10 \% \) as a sound source approaches a stationary observer with constant speed \( v_{\mathrm{s}} \). What would be the percentage change in frequency as the source recedes the observer with
P the same speed. Given that \( \mathrm{v}_{\mathrm{s}}\mathrm{v} \). \( (\mathrm{v}= \) speed of sound in air)
(A) \( 14.3 \% \)
(B) \( 20 \% \)
(C) \( 10.0 \% \)
(D) \( 8.5 \% \)
