A) \[\frac{v}{2}\]
B) 3 v
C) 2 v
D) v
Correct Answer: D
Solution :
By using \[v'=v\left[ \frac{v-{{v}_{o}}}{v-{{v}_{s}}} \right]\] \[2v'=v\left[ \frac{v-{{v}_{o}}}{v-0} \right]\] \[\Rightarrow \] \[{{v}_{o}}=-v\]. Negative sign indicates that observer is moving opposite to the direction of velocity of sound.You need to login to perform this action.
