AI Thread Summary

The discussion centers on the validity of an associative operation involving four vectors, specifically questioning the equation 2*(p+p_1)p_3(p+p_1)p_2 - (p_3)(p_2)(p+p_1)^2 = (p_3)(p_2)(p+p_1)^2. Participants express confusion over the multiplication order and suggest using LaTeX for clarity. An attachment is provided to illustrate the problem further. The main focus is on determining whether the operation is associative. The conversation highlights the complexities involved in vector operations and the need for clear mathematical representation.

hi,

Is it true that

2*(p+p_1)p_3(p+p_1)p_2 - (p_3)(p_2)(p+p_1)^2 = (p_3)(p_2)(p+p_1)^2 ,

where p,p_1,p_2,p_3 are four vectors? Or simply: associative this operation?

ok. See the attachment.

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:
