Is the Calculated Speed and Wavelength of a Sound Wave Accurate?

AI Thread Summary
The calculated speed of the sound wave produced by a smoke alarm 35.0 m away is approximately 339.81 m/s, derived from the distance divided by the time of 0.103 seconds. The wavelength of the sound wave is determined to be 0.33 m, calculated using the speed and frequency of 1.02 x 10^3 Hz. The average speed of sound in air is often cited as 341 m/s, but variations can occur based on conditions. The calculations provided seem accurate based on the given parameters. Overall, the discussion confirms the sound wave's speed and wavelength calculations are correct.

A sound wave produced by a smoke alarm 35.0 m away is heard 0.103 s after having been started by smoke in the air. The frequency of this sound wave is 1.02  103 Hz. Complete the following.

a.Find the speed of this sound wave in air.

b. Find its wavelength and period.


The sound wave in the air, is it always going to be 341m/s if not stated because that's the average?

You are asked to find the speed of sound, you are given a distance and a time - so it shouldn't be too tricky
 
a. Find the speed of this sound wave in air.
S=35.0m/0.103s
S=339.81m/s

b. Find its wavelength and period.

Wavelength=339.81m/s ÷ 1.02x103
Wavelength=0.33m


Hello thank you :)
Does this look right to you?
 

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...
