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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
