    Diffusion Law
AI Thread Summary
To calculate the time required for a spherical balloon to reduce its volume to half due to diffusion, Fick's law of diffusion must be applied. The discussion emphasizes the need to incorporate the Young's modulus of the balloon material, denoted as E, along with the diffusion constant of nitrogen, D. Participants are encouraged to share their attempts and specific challenges to facilitate targeted assistance. The conversation is focused on the application of these scientific principles to solve the problem effectively. Overall, the thread aims to collaboratively derive the solution using the relevant equations and concepts.

Homework Statement



Calculate the time needed for a perfectly spherical balloon with rahis R to reduce its volume to R/2 due to diffusion by applying Fick's law of diffusion. Assuming the young modulus of balloon is E and the gas filled is nitrogen. diffusion constant of nitrogen is D.

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...
