Your experiments on a particular insulator indicate that at 20°C, the average speed of sound in the insulator is vi = 8500 m/s and its bulk modulus is Bi = 370 GPa. Experimental results from your colleague show that a certain metal alloy has a density of ρm = 6500 kg/m3 and a bulk modulus of Bm = 110 GPa.
a. Calculate the density of the insulator ρi in kilograms per cubic meter.
b. Calculate the speed of sound vm in the metal alloy in meters per second.
