Ahh! Its all because my calculator was in degrees, not radians. The reason the other equation worked for me was because I had taken the long way around and made the equation y(x,t) = (3.50mm)sin2pi[(t/25.8s) - (x/.148)]. That should have told me right there that y(x,t) =...
No, that is the equation that we are given. In the homework, it was written slightly different, but I'm positive they are the same:
y(x,t) = (3.55mm)sin[(162s^-1)t-(42.5m^-1)x]
They are the same, right? I got the correct answers for the first 3 parts of the question using it.
I really want to...
Homework Statement
The equation describing a transverse wave on a string is
y(x,t) = (3.50mm)sin[(t/162s) - (x/42.5)]
Find the transverse displacement of a point on the string when t = 0.220 s and at a position x = 0.140m
Homework Equations
y(x,t) = Asin(wt-kx) or y(x,t) =...
I think I got the problem, but can someone check my work? Thanks!
Because q1 and q2 are both positive, the only place that you can put q3 to make fnet = 0 would be between them on the x axis.
F23 = F13
Kq1q3/(r1-x)^2 = kq2q3/x^2
q1/(r1-x)^2 = q2/x^2
q1x^2 = q2(r1-x)^2
q1x^2 = q2(r1^2 - 2r1x...
Hi. I would appreciate some help with this point charge problem. I think I understand the general set up, but don't know where to go from there.
Homework Statement
Two point charges are placed on the x-axis as follows: Charge q1 = +4.00nC is at x=0.400m, and charge q2 = +2.00nC is at...
