    Asteroid Light
AI Thread Summary
Light from an asteroid is primarily visible to the naked eye when it reflects sunlight. The discussion highlights that both options provided (a and b) are identical, leading to confusion. The correct reasoning is that asteroids do not emit their own light but are seen due to sunlight reflection. Participants agree on the importance of understanding this concept. Overall, the visibility of asteroids is contingent on their reflective properties.

That makes more sense. But still, but a and b are the same answer.
 
Thanks a lot
 
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...
