1.	Two cars, each moving with speed u on the same horizontal straight road , are approaching each other Wind blows along the road with velocity w . One of these cars blows a whistle of frequencyf_(1) . An observer in the other car hears the frequency of the whistle to bef_(2) .The speed of sound in still air is v. Correct statement (s) is / are :
Answer» If WIND blows from OBSERVER to the source , ` f_(2) GT f_(1)` If the wind blows from the source to observer ` f_(2) gt f_(1)` If the wind blows from observer to the source ` f_(2) lt f_(1)` If the wind blows from the source to the observer ` f_(2) lt f_(1)` Solution :N/A
