pretty sure this is correct. It is multiplied by 2, because it travels up, then down, then down the 13.9. During this entire period of time gravity is acting on it.

i got q25 xD working on 26
but ya
F = kx
mg = kx
so w = sqrt(g/x)
g = 9.81
x = 0.###/2
w= wtv you got
thnn
f = w / 2pi
voila ^_^
edit: -________-'
i just realized that you already solved that *sigh* sorry.

Heheh, you're kind of a week too late, and that was wrong since you use displacement rather than distance.
But it the thought that counts. |

I need CAPA help again!
I'm struggling with these two questions :(
1. Two waves of light in air, of wavelength 662.3 nm, are initially in phase. They then travel through plastic layers as shown, with L1 = 4.04µm, L2 = 3.44µm, n1 = 1.37, and n2 = 1.63. In wavelengths, what is their phase difference after they have both emerged from the layers?
2. Two speakers are driven by the same oscillator with frequency of 231 Hz. They are located 4.12 m apart on a vertical pole. A man really far away walks straight toward the lower speaker in a direction perpendicular to the pole. How far is he from the pole at the first moment he hears a minimum in sound intensity (short of infinity) if the speed on sound is 330 m/s?
Help anyone? :(

But I recall the prof saying something like, it's just for practice and you can try it out...
I dunno. I'm still doing it. Best bet - Drop-in Help Centre at Thode. That's where I'll be tomorrow. XD

Who's your prof? Hughes didn't say that, as far as I know.

Rheinstadler mentioned it might not be for marks, then he never confirmed anything.
