Two cars are moving on two perpendicular road towards a crossing with uniform speeds of `72km//hr` and `3km//hr`. If first car blows horn of frequency 280 Hz, then the frequency of horn heard by the driver of second car when line joining the cars make `45^@` angle with the roads, will be

Two cars are moving on two perpendicular roads towards a crossing with uniform speeds of 72 km/hr and 36 km/hr. If first car blows horn of frequency 280 Hz, then the frequency of horn heard by the driver of second car when line joining the cars make 45^@ angle with the roads will be

Two cars are moving on two perpendicular roads towards a crossing with uniform speeds of 72 kmph and 36 kmph. If first car blows horn of frequency 300 Hz, then the frequency of horn heard by the driver of second car when line joining the cars make 45° angle with the roads will be (Speed of sound = 330 m/s)

Two cars are moving on two perpendicular roads towards a crossing with uniform speeds of 72(km)/(h) and 36(km)/(h) . If second car blows horn of frequency 280 Hz, then the frequency of horn heard by the driver of first car when the line joining the cars makes angle of 45^@C with the roads, will be (velocity of sound is 330(m)/(s) )

Two cars are moving on two perpendicular roads towards a crossing with uniform speeds of 72(km)/(h) and 36(km)/(h) . If second car blows born of frequency 280 Hz, then the frequency of horn heard by the driver of first car when the line joining the cars makes angle of 45^@C with the roads, will be (velocity of sound is 330(m)/(s) )
