AI Thread Summary
The wave in question has a frequency of 19.0 Hz, an amplitude of 0.18 m, and a wavelength of 0.20 m. The speed of the wave is calculated as 3.8 m/s, derived from multiplying the frequency by the wavelength. The period of the wave is determined to be approximately 0.0526 seconds, calculated using the formula 1 divided by the frequency. The calculations for both speed and period are confirmed to be correct. This discussion highlights the relationship between frequency, wavelength, speed, and period in wave mechanics.

Homework Statement


A wave traveling in the positive x direction with a frequency of 19.0 Hz

The full amplitude of the wave is 0.18 m and the wavelength is 0.20 m

What is the period and speed of the wave?

Homework Equations



speed=(frequency)*(wavelength)
Frequency=1/period

The Attempt at a Solution



I figured the speed by doing 19*0.20 which equaled to 3.8 m/s
For the period, i just did 1/19 and got 0.0526 s but am not too sure about this answer. Please direct me! Thanks!

Your answer is right. 1/19 would be the Period.
 
thanks!
 

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...
