heat transfer
i have a few problems with the question.
1. "thermal conductivity is high " means majority of the heat is conducted and very low amount is absorbed and therfore emitted so how can we find out change of temp of A .
2. temp between the surfaces of A and B is to be taken 0K ??
3. masses are not given so how can we find out rate of change of temp...
NLM
isme the acceleration of block is coming out to be 2g/3 , or acceleration wrt to wedge is 2g/3 cuz if its wrt to ground the answer should be like net acceleration because block has two accelerations one on the left and one along the incline?
Shm question
In this question, why do we ignore work done by friction when applying the energy method(this is what I've seen in most solutions online) cuz when you displace the top rod by a distance x ,Work done by friction should be non zero right? ;
Also is it possible to do this without energy method, I tried but couldn't get the correct answer...
