My bedroom is the furthest away from the AC unit. That means the room is also the hottest in the house with the AC on. Should I put a window fan in the room and blow the hot air out? This will cause the AC to run more and I've broken the "closed loop" system. It should make the bedroom cooler or would it be better to just lower the overall house temp by a couple of degrees. Thanks.

I want to try an experiment for electrical generation with a mocked up faraday flashlight type setup using different shaped magnets and wire coil configurations. In the interest of not spending too much on magnets I would like to know if stronger magnets will increase the amount of electricity generated or increasing the amount of wire in the coil or does it really not make a difference?

I had a test yesterday n not sure if I did this question right:

Q:squareroot(x+y)=1+(x^2)(y^2)

I got the answer y'=[1/2(x+y)^(-1/2)-2x(y^2)]/2(x^2)(y)

(P.S: d/dx both sides and find dy/dx)

Thanks a lot

Here's the question:
"There are 12 stones. The diamond is embedded in one of the stones. Eleven of the stones weigh the same, but the stone containing the jewel weighs either slightly more or slightly less than the others. Find the right stone and find whether it's heavier or lighter. You could use each of the three balance scales exactly once.

Can anyone help me out? My boyfriend and me are working on this one and haven't solved it yet."

I know the answer. Now let's see if you can get it.
