- As shown in Figure P14.37, water is pumped into a tall, vertical cylinder at a volume flow rate R. The radius of the cylinder is r, and at the open top of the cylinder a tuning fork is vibrating with a frequency f. As the water rises, what time interval elapses between successive resonances? Figure P14.37 Problems 37 and 38.arrow_forwardA copper rod with length 1.4 m and cross-sectional area 2.0 cm2 is fastened to a steel rod of length L and cross-sectional area 1.0 cm2. The compound structure is pulled on each side by two forces of equal magnitude 6.00 104 N (Fig. P14.57). Find the length L of the steel rod if the elongations (L) of the two rods are equal.

The cylinder is filled with water until the water level is a distance L = 20 cm from the top. A vibrating tuning fork is placed near the top of the cylinder and the valve is opened so that the length L slowly increases. If the tuning fork has a frequency of f= 510 Hz, determine the next two values of L (in m) that correspond to a resonant mode. (Assume that the speed of sound in air is 343 m/s.)

- A periodic vibration at x = 0, t = 0 displaces air molecules along the x direction by smax = 1.8E-05 m. The motion produces a sound wave that travels at a velocity of v = 350 m/s with a frequency of f = 180 Hz. Take the density of air as ρa = 1.20 kg/m3. a. Calculate the displacement of the air molecules using an function for the traveling sound wave in terms of time and position at time t = 0.001 s and displacement x = 1.0 m. b. Write an expression for the maximum pressure exerted by the sound wave ΔPmax in terms of the air density ρa, the sound velocity v, the angular frequency ω, and the maximum displacement smax. c. The sound wave is directly incident on a sheet of paper of surface area A = 0.037 m2. Calculate the maximum force Fmax, in newtons, exerted on this sheet.arrow_forwardThe speed of sound in a solid medium is given by v = √E/p where E is the value of Young's modulus for the solid and p is the density.

Then add aspoonful of powder (say, chocolate mix or instant coffee) and tapagain as you stir the powder. The frequency you hear has a lowervalue fs because the tiny air bubbles released by the powderchange the water’s bulk modulus. As the bubbles reach the watersurface and disappear, the frequency gradually shifts back to itsinitial value. During the effect, the bubbles don’t appreciablychange the water’s density or volume or the sound’s wavelength. Rather, they change the value of dV/dp—that is, the differentialchange in volume due to the differential change in the pressurecaused by the sound wave in the water. If fs /fi=0.333, what is theratio (dV/dp)s/(dV/dp)i?arrow_forwardDetermine how much the average force acting on the eardrum of the human ear (area S = 66 mm?) is greater than the hearing threshold if the sound pressure is 112,3 Pa. The sound frequency is 1 kHz. The sound pressure corresponding to the hearing threshold is taken equal to 0.02 MPa. Please enter the units of measurement in your answer.arrow_forward
