AI Thread Summary
The wave generator produces 28.6 pulses in 4.10 seconds, leading to a calculated period of approximately 0.143 seconds. The frequency, derived from the period, is about 6.9756 Hz. The relationship between period and frequency is confirmed as T = 1/frequency. The discussion highlights a common misunderstanding in calculating these values, with users correcting their approach. Overall, the calculations illustrate the fundamental principles of wave mechanics.

1. A wave generator produces 28.6 pulses in 4.10 s.

(a) What is its period?
*solved*
(b) What is its frequency?
*solved*
2.
period= 1/freq.
v=wvlngth (freq)
wvlngth= v/freq
3. i tried to find the number of pulses per second, which I think is 6.9756...
idk what to do from there x.x

Periodic time,T, is the time taken for one pulse.
 
so T= 4.1/28.6?
which would be 0.143...?

LOL i was doing it reversed gosh I am so dumb xD thankss :)

and so its frequency would be 1/0.143. Okay n.n Thanks for straightening me out. :)
 

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...
