Not to be lazy or anything, but I was having a lot of trouble on these two physics problems for homework and don't know where to start for either. I think for 1 I use Faraday's Law and for 2 I usee F=BILsin Theta... not sure 1. A square, single-turn coil 0.23 m on a side is placed with...

Sounds like that man was very determined to have you guys baffled, he must have been very upset when you figured it out:rofl:

average super nova, congratz, you are exactly right! Too bad you didnt post it this morning when I needed it :cry: Yes the teacher told us how it was done, and your explanation nailed it. O well, next time you will see my posts earlier :tongue2: Thanks though

look closer... its basically two different circuits, the red wire connects to the cirst switch, goes in the base of the second switch ( not connected) goes under the base of the light bulb( not connected) goes to the second light bulb ( CONNECTS HERE!) and back around (thats 1 complete...

yes I know what a circuit is, but I am saying there is no hidden wire outside the circuit I first drew. There is something hidden in either the switches or the bulb, nothing outside that. I came up with this... http://img494.imageshack.us/img494/6055/circuittrick1ao.jpg" Simple? Seems to...

no, there was no wire hidden in the board, the hidden thing is in the switches or bulb.

So my teacher was showing us this circuit he made in class today, and he won't tell us how it works. This is the picture of the circuit: http://img517.imageshack.us/img517/7576/trickcircuit1tb.jpg" Its an AC circuit, one wire going through two switches, and then two light bulbs. He showed...

To many this would be a simple plug it into equation problem. But for some reason this just isn't clicking for me. Here's the problem: An open elevator is ascending with a constant speed V of 32ft/sec. A ball is thrown straight up by a boy in the elevator when it is a height h of 100 feet...
