8. A certain 63.0-m-long metal rod is struck at one end. A person at the other end hears two sounds as a result of two longitudinal waves. These two sounds are traveling in the metal rod and the other traveling in air. What is the time interval (in seconds) between the two sounds? Treat speed of sound in air to be 337 m/s. Also, Y = 9.7 × 10¹⁰ Pa, rho = 9204 kg/m³. Express your final answer in 3 decimal places.
