Relationship between resistivity and Mathiessen's Rule

AI Thread Summary
The discussion revolves around calculating the resistivity of an alloy using Mathiessen's rule, which states that the total resistivity is the sum of the resistivities due to different scattering mechanisms. An alloy has a resistivity of 1.2e-6Ωm at 300K, which increases by 10% when heated to 973K. Participants encourage the original poster to share their attempts and clarify Mathiessen's rule for better assistance. The conversation emphasizes the importance of showing work to facilitate effective help. The thread highlights the challenges faced in applying theoretical concepts to practical problems.

This question has bogged me down for hours. Please help.

An alloy of metals is found to have a resistivity of 1.2e-6Ωm at 300K. When it is heated to a temperature of 973K, the resistivity is found to increase by 10 per cent. Assuming Mathiessen's rule to hold good for the alloy, find its resistivity due to inpurities scattering alone.

Hi Lindoc! Welcome to PF! :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:

(Also, state Mathiessen's rule so we don't have to look it up! :redface:)
 

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...
