A solid copper object hangs at the bottom of a steel wire of negligible mass. The top end of the wire is fixed. When the wire is struck, it emits sound with a fundamental frequency of 300 Hz. The copper object is then submergedin water so that half its volume is below the water line. Determine the new fundamental frequency.
Suppose fluid B has 4.6 times the bulk modulus
and 1.2 times the density of fluid A. Find the ratio
of the speed of sound in fluid B over the speed of
sound in fluid A.
Sound exerts a pressure on the human ear. This pressure P, measured in dynes per square centimeter, increases as the loudness of the sound increases. As the loudness D, measured in decibels, increases, the pressure increases by 12.2% per decibel. Furthermore, a sound of loudness 97 decibels produces a pressure of 15 dynes per square centimeter.
Find P(0) and use it to give a formula for P = P(D) in this situation.a) P(0) = 0.0002122; P(D) = 0.0002122(1.122)^Db) P(0) = 0.0002122; P(D) = 0.0002122(2.122)^Dc) P(0) = 0.0002122; P(D) = 0.0002122(2.252)^Dd) P(0) = 0.0002122; P(D) = 0.0002122(3.124)^D
