    Air Sound Speed
AI Thread Summary
The speed of sound in air is independent of frequency, meaning that both 100Hz and 200Hz sound travel at the same speed. The speed of sound is primarily determined by the temperature of the air, which is not provided in the discussion. The formula for calculating the speed of sound in air is v = (331 + 0.606Tc) m/s, where Tc is the temperature in Celsius. Therefore, the question of comparing the speeds of 100Hz and 200Hz sound does not require frequency-based calculations. Understanding that sound speed is a material property related to density and elasticity clarifies this concept.

Homework Statement


compared to the speed of 100Hz sound the speed of 200Hz sound through air is?


Homework Equations


i thought i needed the temp of air to fiigure this question out, but the temp is not given? is this question as simple as 200/100 or no??


The Attempt at a Solution



speed of sound in air = v=(331+0.606Tc )m/s?

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...
