Solution

The correct option is B $348.3 m / s$
$V t = V_{0} + 0.61 t$
$V 30 = V_{0} + 0.61 \times 30$
$= 330 + 18.3$
$= 348.3 m / s$

A train, standing in a station-yard, blows a whistle of frequency 400 Hz in still air. The wind starts blowing in the direction from the yard to the station with at a speed of 10 m s^–1. What are the frequency, wavelength, and speed of sound for an observer standing on the station’s platform? Is the situation exactly identical to the case when the air is still and the observer runs towards the yard at a speed of 10 m s^–1? The speed of sound in still air can be taken as 340 m s^–1.
