    Time Wavelength
AI Thread Summary
To calculate the time it takes for a 1000Hz noise to reach someone 3 meters away, the speed of sound, which is approximately 340 m/s, is used. The time can be calculated using the formula time = distance/speed, resulting in approximately 0.0088 seconds. The wavelength can be determined using the formula wavelength = speed/frequency, yielding a wavelength of 0.34 meters. Understanding the relationship between frequency and wavelength is essential, as they are connected through the universal wave equation. This discussion highlights the straightforward application of basic physics formulas to solve sound-related problems.

Hi,

"Somebody makes a noise with a frequency of 1000Hz. Calculate how long it will take to reach somebody 3m away. What will be the wavelength?"

I can't figure out how it fits into any of the formulas I have!


Thanks! :)

What formulas do you have?

What's the speed of sound?
How are frequency and wavelength related?
 
basically just the universal wave equation. the speed of sound is 340m/s.
 
Good. That's all you need to solve this problem.
 

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...
