Thermal radiation question. Please help me explain the theory

AI Thread Summary
The discussion centers on the principles of thermal radiation, specifically regarding how the body interacts with its environment. It highlights that if the skin is warmer than the surroundings, the body emits more energy than it absorbs, leading to cooling. The participants clarify a misunderstanding about the temperature relationship, confirming that the skin should indeed be warmer. The significance of this concept is emphasized in understanding energy transfer. Overall, the conversation reinforces the importance of accurate temperature descriptions in thermal radiation theory.

I agree with your answer to part a). And I think you've also written the right answer for part b): "I know that since the skin is colder than the surroundings, the body will emit more engery than it absorbs and it will cool." I think this is what the question is looking for when it asked for the significance.

EDIT: woops, it should be that the skin is warmer than its surroundings. I'm guessing you just wrote colder by accident, because it looks like you understand the principles pretty well.
 


Yes, that was by accident!

Thanks for confirming!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
