Hmm that gives me the answer I had already come up with which was incorrect, 9.935. Let me make sure I'm following you right
Path difference = Sqrt(x^2 + 4^2) - x
Here I'm plugging in wavelength/2, thus
.775 = Sqrt(x^2 + 4^2) - x
which brings me to
(x+.775)^2= x^2+ 4^2
which eventually goes...
Excuse my poor handwriting. . .
After plugging in all variables I came up with 9.94, which is incorrect. Is N supposed to equal 0 for this problem?
p1 is from the bottom speaker to the listener and p2 is the hypotenuse
Homework Statement
Speaker 1 is positioned at the origin and speaker 2 is at the position (0, 4.00) meters. They emit identical sound waves of wavelength 1.55 m, in phase. If you stand on the x-axis at (x, 0) meters, what is the smallest positive value for x for which you experience complete...
Homework Statement
A stuntwoman is preparing to take a punch, crash through a "candy glass" window, and fall a long distance. The script calls for her to emit a piercing scream just before she hits the "ground." In reality, she will land on a waiting airbag. Lights! Camera! Action! The...
Hmm still confused. I think I am getting the angles in the wrong places. Is it Fgx= 30.38/cos32?
Edit
I don't think that's right. . . i don't know where I'm going wrong
Homework Statement
A block of mass 3.1 kg rests on a frictionless inclined plane, held in place by a string of mass 0.023 kg. The angle of the plane from the horizontal is 32°, and the string length is 1.5 m. How long does it take a wave to travel from one end of the string to the other? Note...
