    Displacement Wave
AI Thread Summary
The wave described by the equation y = 0.13 sin(t - 3.82x) is traveling in the +x direction. To find the displacement y at t = 26.5 seconds and x = 6.4 meters, one must substitute these values into the equation. The process involves basic arithmetic rather than complex physics concepts. The discussion highlights a lack of understanding of wave mechanics and a need for clearer instructional resources. Overall, the focus is on solving for wave displacement using given parameters.

Homework Statement


The displacement (in meters) of a wave is y = 0.13 sin(t - 3.82x), where t is in seconds and X is in meters.

(a) Is this wave traveling in the +x or -x direction?


1.+x direction.
2.-x direction

(b) What is the displacement y when t = 26.5 s and x = 6.4 m?




The Attempt at a Solution




The solution for part a is positive x direction
I cannot figure out how to do this problem at all. Professor did not cover this material and I have no background knowledge in vibrations or waves. I have been reading the chapter in the book, but it doesn't make any sense and doesn't have any equations. I'd really appreciate a good teacher right now. :)

I don't see any physics in this question! It is just some arithmetic work. You must substitute t = 26.5 s and x = 6.4 m into the equation
y = 0.13 sin(t - 3.82x)
and find the value of y.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
