    LEARN MORE REMARKS If the train were going away from the observer, v, - -40.0 m/s would have been chosen Instead. QUESTION Does the Doppler shift change due to temperature variations? If so, why? For typical daily variations in temperature in a moderate climate, would any change in the Doppler shift be best characterized as nonexistent, small, or large? Yes. A change in temperature changes the speed of sound and the Doppler shift, but only Insignificantly No. Temperature does not...
