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...
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...
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:
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...
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...
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...
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...
