A mass is attached to the hanging end of the string. The distance between the speaker and the pulley is [ = 0.761 m. The entire length of the string is 1.07 m and the mass of the string is measured to be 0.361*10" kg. The speaker is connected to a function generator that is set to produce a sinusoidal waveform having frequency 54 Hz. m @theexpertta.com CA 25% Part (a) Determine the wavelength, in meters, of the standing transverse wave in the string for the third harmonic. 1 = sin cos( tan( I 7 8 9 HOME cotan( asin() acost E 4 6 ing atan() acotan() sinhO 1 2 3 cosh() anh() cotanh( 0 END O Degrees O Radians BACKSPACE CLEAR Submit Hint Feedback I give up!
