Direction Divergence Divergence theorem Normal Theorem

AI Thread Summary

In applying the divergence theorem, the normal vector must always point outward from the system. The discussion highlights confusion regarding the negative sign associated with the base vector aR. This negative sign indicates the direction of the vector relative to the outward normal. Understanding the orientation of vectors is crucial for correctly applying the theorem. Clarifying these vector directions ensures accurate calculations in fluid dynamics and electromagnetism.

The problem is in the paint doc.. My question is why is the base vector a_R have a negative sign attached to it?

In applying the divergence theorem, the normal vector is always outwardly directed from your system.

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
