    Frequencies Wave
AI Thread Summary
The discussion centers on calculating the frequency of a wave given its pressure equation, Δp = (1.3 Pa) sin π[(3.00 m^-1)x - (300 s^-1)t]. The user initially identifies the angular frequency as 300 s^-1, equating it to 300 hertz. However, they incorrectly calculate the frequency as 47.746 by dividing the angular frequency by 2π. There is a request for clarification on the formula substitution process, indicating confusion over unit representation in the calculations. The thread highlights the importance of clear formula presentation to avoid misunderstandings in wave frequency calculations.

Homework Statement



Δp = (1.3 Pa) sin π[(3.00 m^-1)x - (300 s^-1)t].

Is the pressure of a wave.

Find frequency

Homework Equations





The Attempt at a Solution



Angular frequency = 300s^-1 = 300 hertz.

Frequency = angular frequency / 2pi = 47.746

Someone, please explain how I managed to screw up that very simple equation.

Can you explain what the red bit is all about.

[Note: it may be some modern technique, but I hate it when a formula substitution is full of individual units. Makes trying to read it next to impossible. Even if the formula you were about to substitute into was written first would be a help]
 

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...
