In the arrangement shown in the figure below, an object of mass m = 2.0 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is L = 2.0 m. (Ignore the mass of the vertical section of the cord.) The left end of a horizontal cord of density ? is connected to a vibrator at point P. A distance L from point P, the cord goes over a pulley and hangs down. A block of mass m connects to the hanging end of the cord. The vibrator causes the portion of cord between point P and the pulley to oscillate such that standing waves are generated. (a) When the vibrator is set to a frequency of 130 Hz, a standing wave with six loops is formed. What must be the linear mass density of the cord? kg/m (b) How many loops (if any) will result if m is changed to 72.0 kg? (Enter 0 if no loops form.) loops (c) How many loops (if any) will result if m is changed to 14 kg? (Enter 0 if no loops form.) loops

Problem 19: While visiting the Albert Michelson exhibit at Clark University, you notice that a chandelier (which looks remarkably like a simple pendulum) swings back and forth in the breeze once every T = 6.5 seconds.Randomized VariablesT = 6.5 seconds Part (a) Calculate the frequency of oscillation (in Hertz) of the chandelier. Part (b) Calculate the angular frequency ω of the chandelier in radians/second. Part (c) Determine the length L in meters of the chandelier. Part (d) That evening, while hanging out in J.J. Thompson’s House O’ Blues, you notice that (coincidentally) there is a chandelier identical in every way to the one at the Michelson exhibit except this one swings back and forth 0.11 seconds slower, so the period is T + 0.11 seconds. Determine the acceleration due to gravity in m/s2 at the club.

An object of mass m is suspended to a rigid support with the help of a spring of force constant K. It vibrates with a frequency 2 Hz (Figure-a). Next two identical objects A and B, each of mass m, are joined together by a spring of force constant K'. Then these are connected to rigid supports S1 and S2 by two identical springs, each of force constant K (Figure-b). Now, if A is clamped, B vibrates with a frequency 2.5 Hz. Calculate the frequencies of the two modes of vibration.
2.52.There is a whistle attached to each end of a 3.4m long stick. As shown in the picture on the right, the bar rotates at an angular speed of 20 rad/s in the horizontal plane with the line passing through the center of the bar as the axis. What is the maximum number of beats per second observed by a person far away from this bar? (However, the vibration frequency of the sound coming from the whistle is 99Hz, and the speed of sound is 340m/s.) N=rw=34m/ дан 20 rows/s w = 20 rad/s
