Question

A string with a mass of 5.00 g and a length of 4.00 m has one end attached to a wall; the other end is draped over a pulley and attached to a hanging object with a mass of 7.00 kg. If the string is plucked, what is the fundamental frequency of vibration? Hz -12 points PSE6 18.P.036. My Note The overall length of a piccolo is 27.0 cm. The resonating air column vibrates as in a pipe open at both ends. (a) Find the frequency of the lowest note that a piccolo can play, assuming that the speed of sound in air is 340 m/s. Hz (b) Opening holes in the side effectively shortens the length of the resonant column. If the highest note a piccolo can sound is 4000 Hz, find the distance between adjacent antinodes for this mode of vibration. mm
