    Ratio Rms Speed
AI Thread Summary
The discussion focuses on calculating the ratio of the root mean square (RMS) speed of oxygen to nitrogen molecules in a gas mixture. The molar masses provided are 32 g/mol for oxygen and 28 g/mol for nitrogen. The RMS speed can be expressed using the formula v_rms = sqrt(3RT/M), where R is the gas constant, T is the temperature, and M is the molar mass. The calculated ratio of the RMS speeds results in approximately 0.935. The confusion arises from the lack of specified quantities of each gas in the mixture, but the RMS speed equation can still be applied effectively.

Homework Statement


A container is filled with a mixture of nitrogen and oxygen. What is the ratio of the rms speed of oxygen molecules to that of nitrogen molecules? (Molar mass of oxygen=32gmol-1; molar mass of nitrogen=28gmol-1).


Homework Equations


v2=(v12+v22+...+vN2)/N


The Attempt at a Solution


Tried using momentum mv=mv but doesn't make sense to do that (even more because the question asks for rms speed) Answer is 0.935. Can't think of sensible ways to use rms speed equation provided above. The question doesn't even specify number of molecules of each so very confused. Please help...

You can express the RMS speed in terms of different quantities.

RMS speed, see the first formula.

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...
