A 32.0 cm violin string with linear density 0.66 g/m is placed near a loudspeaker that is fed by an audio-oscillator of variable frequency. It is found that the string is set in oscillation only at frequencies 880 and 1320 Hz. as the frequency of oscillator is varied continuously over the range 500 to 1500 Hz. What is the tension (in newtons) in the string?
For my project I constructed a trebuche. A trebuche is an ancient device used for launching projectiles. It acheives this by harnessing potential energy and allowing this potential energy to convert into kenetic energy. This potential energy is st..
