AI Thread Summary
A wave traveling at 5 cm/s in the positive x direction will have its intercepts shift over time. At t=0, the intercepts are at 1 cm and 4 cm. By t=2, the intercepts will move to 11 cm and 14 cm, maintaining the same wave shape. The graph will look identical in form, just translated along the x-axis. This confirms that the wave's position changes with time while its characteristics remain constant.

i just want to double check this is right because i am not given answers.
i have a wave traveling at 5cm/s traveling in the positive x direction.
when t=0 it has intercepts at 1cm and 4cm.
if i have to draw the graph at t=2
will the graph look exactly the same except the intercepts are at 11cm and 14cm?

Yes.
 
thanks!
 
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...
