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.
A copper block is suspended from a wire, as in part 1 of the drawing. A container of mercury is then raised up around the block, as in
part 2, so that 42.0% of the block's volume is submerged in the mercury. The density of copper is 8890 kg/m³, and that of mercury is 13
600 kg/m³. Find the ratio of the fundamental frequency of the wire in part 2 to the fundamental frequency in part 1.

- In about 1657, Otto von Guericke, inventor of the air pump, evacuated a sphere made of two brass hemispheres (Fig. P15.62). Two teams of eight horses each could pull the hemispheres apart only on some trials and then with greatest difficulty, with the resulting sound likened to a cannon firing. Find the force F required to pull the thin-walled evacuated hemispheres apart in terms of R, the radius of the hemispheres; P, the pressure inside the hemispheres; and atmospheric pressure P0.

Answer in units of °C.arrow_forwardWhen the heart pumps blood into the aorta, the pressure gradient—the difference between the blood pressure inside the heart and the blood pressure in the artery—is an important diagnostic measurement. A direct measurement of the pressure gradient is difficult, but an indirect determination can be made by inferring the pressure difference from a measurement of velocity. Blood is essentially at rest in the heart; when it leaves and enters the aorta, it speeds up significantly and—according to Bernoulli’s equation—the pressure must decrease. A doctor using 2.5 MHz ultrasound measures a 6000 Hz frequency shift as the ultrasound reflects from blood ejected from the heart.a. What is the speed of the blood in the aorta?b. What is the difference in blood pressure between the insideof the heart and the aorta?
