This is what I have come up with so far. (384)(l)=\frac{(1)(343)}{2} l=9.45m

Homework Statement What length of open pipe is needed to give resonance to a 384 Hz sound? Assume the speed of sound to 343 m/s. Homework Equations f=\frac{nv}{2l} The Attempt at a Solution I am lost as to how to even start this problem.

Homework Statement Lighting strikes the ground 1.00 km form an observation point. Calculate the delay between seeing the flash and hearing the thunder. (Temperature @ 15⁰C)(Speed of light = 2.99 x10⁸ m/s) Homework Equations v=331+(0.6)T The Attempt at a Solution Speed of the...

Thanks! Have not done Physics in so long and now have a bunch I need to do. V= 21.6 ?

Homework Statement A vibrating rope has a linear density of 0.075 kg/m. If a tension of 35 N is applied to the rope what will be the speed of a wave traveling along the rope? Homework Equations v=\sqrt\frac{F}{m/L} The Attempt at a Solution Just wanted to see if I am headed...

Homework Statement A string whose linear density is 0.00500 kg/m is stretched to produce a wave speed of 85 m/s. What tension was applied to the string. Homework Equations v=√(F/(m/L)) The Attempt at a Solution v=0.00500 kg/m m/L= 85 m/s I can't seem to re-arrange the...
