The engine of a train moving with speed \(10 \mathrm{~ms}^{-1}\) towards a platform sounds a whistle at frequency \(400 \mathrm{~Hz}\). The frequency heard by a passenger inside the train is: (neglect air speed. Speed of sound in air \(=330 \mathrm{~ms}^{-1}\) ) ๐Ÿ“ฒPW App Link - https://bit.ly/YTAI_PWAP ๐ŸŒPW Website - https://www.pw.live
