Physics: Simple Harmonic OscillatorTraveling waves are set up in a pair of long strings by a simple harmonic oscillator. The strings have identical mass densities of 5.1 grams/meter. Both strings terminate at a short bungee cord attached to a wall. The harmonic oscillator is attached to the other ends of the strings in such a way that one string is 5.4 meters longer than the other. If the oscillator has frequency 97 Hz:
Give at least two string tensions which will produce the minimum motion of the bungee cord.
assume a long, straight wire carries a current of 6.5 .what would be the frequency of vibrations.
