AI Thread Summary
The discussion revolves around a homework problem related to gases in physics and chemistry, specifically addressing the equation K = 3nRT. Participants express confusion about the relationship between mass and kinetic energy, noting that while K does not directly depend on mass, moles are proportional to mass. The conversation highlights the importance of understanding how changes in mass affect kinetic energy through the number of moles. There is a request for clarification on the mathematical reasoning behind the problem. The thread emphasizes the interconnectedness of mass, moles, and kinetic energy in gas-related equations.

please anybody?
 
? ANyone know?
 
mathematically I don't see how i am wrong
 
You have K = 3nRT. There's no mass in this equation. K does not depend on mass.
 
yes but moles is directly proportional to mass so decreasing mass will decrease mass which will decrease kinetic energy right?
 

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'

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...
