Two traveling waves g(x,t) = Asin(kx-wt) and h(x,t) = Asin(kx+wt+phi)

AI Thread Summary
The discussion revolves around identifying nodes in the superposition of two traveling waves, g(x,t) = Asin(kx-wt) and h(x,t) = Asin(kx+wt+phi). Participants note that the provided figure does not display nodes or antinodes because it does not plot the combined function g+h. To determine the locations of nodes, one must find points where g+h equals zero. The conversation suggests that the original question may be part of a multiple-choice format, prompting further clarification on the question and possible answers. Understanding the conditions for nodes is crucial for solving the problem effectively.

Where in the figure are there nodes at t1?
Please post your working.
 
Hi haruspex, thank you for yr time to have a look at my question. the Figure doesn’t include nodes/anti nodes.

That's only because the figure doesn't plot g+h. You can easily see where the nodes must be.

You seem to have completely misunderstood the question.
You have to find a place where g+h is always zero.
 
The "statement" of the problem looks like one of the possible answers to a multiple choice question. If that is true, what is the question and what are the other choices?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

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 'Trying to understand the logic behind adding vectors with an angle between them'

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
