Understanding Stationary Waves in Open and Closed Tubes

AI Thread Summary
The discussion centers on understanding stationary waves in tubes with one end open and one closed. Participants seek clarification on how to sketch the stationary wave patterns for the fundamental and next highest modes, specifically regarding the displacement of pressure. There is confusion about the physical quantity to be graphed on the vertical axis, with suggestions that it may involve length on the x-axis. Participants also express uncertainty about whether a graph was provided or if they need to create one from scratch. Clear guidance on the sketches and the physical quantities involved is needed for a comprehensive understanding.

Homework Statement


For a tube with one end open and one closed
a) Draw a labelled sketch of the stationary wave patter for (i) the fundamental and (ii) the next highest mode.

b)describe the physical quantity graphed (as the verticle axis, i.e. the dependent variable)

c) clearly explain the reason for the behaviour of this quantity at (i) the closed and (ii) the open end

The Attempt at a Solution


For a) would I draw a sketch of the displacement of the pressure?
part b) just seems like one of those weird questions that has nothing to do with part a:confused: . Can somebody help me to decypher it?

thanks!

My guess is the question wants you to graph some physical quantity on the y-axis and length on the x-axis. So 'sketch' must mean 'graph' ?

Or they've provided a graph and you've missed it ?
 
no graphs anywhere :confused:

What do you recommend I draw for a)?
 

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...
