A. The bulk modulus for a given fluid is 1.73E+9 N/m2. Use this value to find the speed of sound in this fluid, assuming a density of 1.00E+3 kg/m3.
B. The speed of sound in a different fluid is 1360 m/s. What is the bulk modulus for this fluid? The density of this fluid is 13500 kg/m3.
According to legend, to determine whether the king's crown was made of pure gold, Archimedes measured the crown's volume by find out how much water it displaced. The density of gold is 19.3g/cm^3. If the crown's mass was 6.00 * 10^2g, what volume ..
