(a) In a liquid with density 1300 kg/m3longitudinal waves with frequency 400 Hz are found to have wavelength 8.00 m. Calculate the bulk modulus of the liquid
(b) A metal bar with a length of 1.50 m bas density 6400 kg/m3. Longitudinal sound waves take 3.90 X 10-4 s to travel from one end of the bar to the other. What is Young's modulus for this metal?
