A 111 V electric iron draws 8.9 A of current. How much heat is developed per hour? Answer in units of J.

P = IV
P = U/t
U = IVt
U = 8.9(111)(60) = 59274 J

Apparently I'm wrong and I don't know why.

A = (C/s)

You have 60 mins, your units have a missmatch.

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...
