    Problem related to pulley system and velocity

    Correct me if I am wrong but I think that the conservation of momentum applies here. The momentum of A and B is must be equal and opposite to the momentum of W.

    Equivalent resistance of simple circuit

    Think about drawing this in a different way so you can see the parallel and series resistors more clearly

    Graduate How Can Light Be Affected by Black Holes Despite Having No Mass?

    Hey guys, I was reading that even light can't escape black holes due to the huge gravitational force which they have. I have been mulling it over for awhile now and I am still stumped. How can a force dependent on the mass of the two bodies act on a body-light/photons which have no mass?

    Equilibrium of a Rod Problem: Find Minimum Distance x

    The way I did mine was: We need to find the Fb in terms of w then we can eliminate it from the final answer as all the terms in the torques will have w. So I found 0.42Fn=Ff and that Fn=Fbcos30. From there i found Ff in terms of Fb and then put this into Fy to find Fb in terms of w. From here...

    But why do I use the Va- vb and then in the denominator use Ub-Ua?
