A car moving at a velocity of 17 ms^(-1)towards an approaching bus that blows a horn at a frequency of 640 Hz on a straight track. The frequency of this horn appears to be 680 Hz to the car driver. If the velocity of sound in air is 340 ms^(-1) , then the velocity of the approaching bus is |

Answer» `2ms^(-1)` Here, `v. = 600 Hz, v= 640 Hz` `v = 340 ms^(-1)` and `v_(0) = 17 ms^(-1)` `v_(s) = 4MS^(-1)` |
