    Could open tube and closed (at one end) tube produce the same frequency?

    Hmm. Does this have anything to do with the 9th harmonic of a closed tube? Or am I totally off?

    Could open tube and closed (at one end) tube produce the same frequency?

    Homework Statement Is it possible for a flute (tube open at both ends) 72 cm long and an oboe (tube open at one end) 64.8 cm long to produce the same note? Prove your answer. Homework Equations v=f\lambda L=(n/2)\lambda (tube open at both ends) L=((2n-1)/4)\lambda (tube open at...

    Constructive or destructive interference- Car radio

    Sorry! I think I've figured it out. Finding wavelength: lambda=v/f =(3)(10^8) / (8.95)(10^7) =3.352 m And then, to find out if the wave hits the wall at a node or an antinode: 56.983m / 3.352m = 16.9997 Which can be rounded to 17 full wavelengths from the antenna to the wall. And because it...

    Constructive or destructive interference- Car radio

    Thanks everyone :) I got 3351955.307 for the wavelength, so I know it is not an integer, and the interference is thus destructive. I still don't understand how that explains why it is destructive.. :confused:

    Constructive or destructive interference- Car radio

    Homework Statement A car’s radio antenna is located at a distance of 56.983 m from a brick wall, which is assumed to act like a dense barrier. The car is attempting to listen to an FM radio station with a frequency of 89.5 MHz. These waves travel at the speed of light, 3.00 × 108 m/s. The...

    Does size or mass of a shoe affect its coefficient of friction?

    Homework Statement For a shoe, does its size or mass affect its coefficient of friction? Explain their effects. Homework Equations Ff=muFn The Attempt at a Solution I'm thinking the mass does (because you need the mass to find the normal force) and the size doesn't because it isn't...

    Can Savannah Catch the Accelerating School Bus?

    Thank you for your help :) I discussed the problem with some friends and now I have this: Savannah d=v1t+1/2at2 d=6.4t+0 (no acceleration) d=6.4t Bus d=v1t+1/2at2+30 d=(1/2)(1.1)t2+30 d=0.55t2+30 Savannah = Bus 6.4t=0.55t2+30 0.55t2-6.4t+30=0 and I did the quadratic...

    Can Savannah Catch the Accelerating School Bus?

    Homework Statement My teacher gave our class a set of questions that are supposed to be challenging. This question has particularly stumped me... I can make a diagram, but I really don't know what to do next: Savannah has just stepped out her front door, only to find that the school bus...
