Finding the path of an oscillating string

AI Thread Summary
The discussion centers around a problem involving the oscillation of a string, specifically questioning the meaning of "pass a point of 0.2 minutes." Participants express confusion over the phrasing, noting that "0.2 minutes" does not represent a valid point in time. One contributor suggests that the question may actually be asking for the displacement of the string after 0.2 minutes, assuming the displacement starts at zero. The need for clarification on the problem's wording is emphasized, indicating potential translation issues. Overall, the conversation highlights the importance of precise language in physics problems.

Homework Statement
The amplitude of the undamped oscillation of the point of the string is 1 mm, and the frequency is 1 kHz. What path will pass a point of 0.2 minutes?
Relevant Equations
V=f x lamda

I don't understand the question. Please help

The wording of the problem makes no sense at all. For one thing "pass a point of 0.2 minutes" is nonsense. "0.2 minutes" is not a point. Do you have the EXACT wording of the problem? Is this being translated into English from another language?

I agree
A student of mine who went to Ukraine asked me this
I'll ask him ok
Thank you very much
 
Here's a guess: they want the displacement of the point after 0.2 minutes. But you have to assume the displacement is zero at the start.
 

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'

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...
