AI Thread Summary
Part B requires an understanding of heat transfer through conduction, specifically using the formula Q/t = dTKA/x. The key variables include Q/t as the heat current, dT as the temperature difference (140 in this case), K as the thermal conductivity (0.04), A as the cross-sectional area, and x as the length of the cross-section. Clarification on the question helped the user find the answer they needed. Understanding the formula and its components is essential for solving the problem.

Could someone tell me what I'm supposed to do for part B please. I don't know what the question is asking :(

This question is with regards to the heat transfer through conduction.

Heat Current means Total heat energy liberated per second.

Go for the formula:

Q/t=dTKA/x

Where Q/t=heat current

dT=difference in temeperatures on both side of the walls(140 in the question)

K=Thermal conductivity=0.04 (given)

A=Area of the cross section

x=length of the cross section
 
Thanks I got the answer, I just needed to understand what PartB was asking
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
