A source of sound is placed at one end of an iron bar 2 km long. Two sounds are heard at the other end at an interval of 5.6s. If the velocity of sound in air is `330m//s`, find the velocity of sound in iron.

At one end of a steel bar of 1 kilometre length, a source of sound is placed and two sounds are heard at the other end at an interval of 2.74 seconds. Calculate the velocity of sound in steel if velocity of sound in air is 340 ms^(-1) .

Two sounds are heard at the end of an iron rod 5 km long at an interval of 14 seconds, when a source of sound is placed at the other end of the rod. The velocity of sound in air is 330 m/s. the velocity of sound in iron is aproximately
