- A typical flute is about 66 cm long. A piccolo is a very similar instrument, though it is smaller, with a length of about 32 cm. How does the pitch of a piccolo compare to that of a flute?A block with a speaker bolted to it is connected to a spring having spring constant k = 20.0 N/m, as shown in Figure P14.79. The total mass of the block and speaker is 5.00 kg, and the amplitude of the unit’s motion is 0.500 m. If the speaker emits sound waves of frequency 440. Hz, determine the (a) lowest and (b) highest frequencies heard by the person to the right of the speaker.A cable with a linear density of u = 0.210 kg/m is hung from telephone poles. The tension in the cable is 550.00 N. The distance between poles is 24 meters. The wind blows across the line, çausing the cable resonate. A standing waves pattern is produced that has 3.0 wavelengthš between the two poles. The air temperature is T'= 24°C. What are the frequency and wavelength of the hum? A =
- A stretched string fixed at each end has a mass of 40 g and a length of 6 m. The tension in the string is 43 N. What is the vibration frequency for the third harmonic? o 20.08 Hz o 53.75 Hz o 6.69 Hz o 13.39 HzWorld-renowned bluegrass musician, Frog Newton, has invited you to join his band. It is apparent that he is only looking for eye-candy on the stage, because you are only asked to play one note, the C at a frequency of 525 Hz. You make your own instrument using a string that is 0.5 meters long and has a mass of 2 grams. Now you need to calculate the necessary tension on the string, And you will be ready to jam! What is the wavelength of the first harmonic (also called the fundamental frequency) of standing wave created by the vibrating string m Submit Answer Tries 0/2 At what speed would a wave propagate on this string? m/s Submit Answer Tries 0/2 What is the linear density of the string? kg/m Submit Answer Tries 0/2 What is the tension needed to produce the C note?World-renowned bluegrass musician, Frog Newton, has invited you to join his band. It is apparent that he is only looking for eye-candy on the stage, because you are only asked to play one note, the E at a frequency of 330 Hz. You make your own instrument using a string that is 1 meters long and has a mass of 3.5 grams. Now you need to calculate the necessary tension on the string, And you will be ready to jam! What is the tension needed to produce the E note?
- A steel piano wire is 82.0 cm long and has a mass of 2.80 g. If the tension of the wire is 590 N, what is the sixth harmonic frequency?8 A 1.0 m1.0 m long pipe held vertically is inserted into a tank of water. This creates an open-closed pipe whose length can be easily varied. When a tuning fork is held at the open end and the pipe is slowly pulled out of the water, resonances are observed when the top of the pipe is 16 cm and 48 cm above the top surface of the water, and no resonances are observed in between. What is the frequency of the tuning fork? Use 340 m/s for the speed of sound. 240 Hz 530 Hz 610 Hz 710 Hz 850 Hz Correct.
