Please solve the Q25

25.   A sound is produced at one end of a long steel rail. Two distinct sounds are observed on the other end of this rail. Why ? The time gap between these sounds is found to be 0.35 second. What is the length of the rail ? Speed of sound in air = 330  m   s - 1 . Speed of sound in steel = 5100 m   s - 1 .
                                                                                                                                     [123.5 m]


Dear Student,
                         Let length of the rail is Lthen time taken by sound in the rail=L5100=t1time taken by sound out of the rail=L330=t2Then according to question t2-t1=.35=L330-L5100L=123.5m
