Wood and Copper are heated upto a steady state condition which will have a higher average of temperature at points ?
Please state your mathematical approach
1. Homework Statement

Dimensions remain same for both the materials as well as the temperatures both are heated to is the same

Homework Equations


This is one dimensional heat transfer mainly with a steady state condition

The Attempt at a Solution


I have tried using Thermal Flux Fourier law as well as the normal GEE but both turned out same
 
Physics news on Phys.org
Turned out same as in the average of the temperature at points was equal
 
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
