As for the note that was left for one of them. Did it say, "Wilbur, come to the bicycle shop. I have an idea" or Orville, come to the ...?

grr i cant find the answer to this problem. here it is:

A well-stirred mixture of ice and water is at equilibrium. If a small amount of warm water or ice is added, the temperature doesn't change why?

A piece of wood furniture was being painted at my shop. it was sprayed with nitro cellulose sealant. The painter then sanded the surface, looked down for some sand paper or to show something to one of his partners and all of a sudden a fireball blasted, almost reaching a 20 feet roof. Luckily, no one was harmed, and apparently, the wood cabinet didn't suffer that much, and it can be restored, but i need to know if such thing is possible and why, because is a very dangerous thing to happen, and i also need to know if this guy was smoking or something.

sin(θ-45º) = √2 / 2 (sinθ-cosθ)


tan(A + π/4) = tanA+1/1-tanA


2+cos²A - 3cos^4A = sin²A(2+3cos²A)

I'll use values to try and get my question across. If a 1 kg block is being dropped straight down, will it have the same potential energy as a block attached to a 1m string being dropped from 90 degrees assuming it stops at 0 degrees? Assuming I did the calculations properly (1 x 9.81 x 1) the potential energy should be 9.81 for free fall. Would this be the case in the other situation?

My question is a general question and has nothing to do with just our earth. This is kind of like asking if there is a starting point and an ending point in our universe.

I am trying to use one hot side of a irrigation system generator, with the other wire of the socket tied to ground. The bulb lighted for about 5 minutes....seemed great. Then it blew out the screw-in base. Should I switch leads on the socket? Or use a limiting fuse? Maybe the hot side should be on the point of the bulb, huh? The bulbs are $9 apiece and I don't want to burn out another one.
