1. ### Question on Electromagnetism. Specifically to do with speed of an object in a field.

Homework Statement Problem is http://imgur.com/bQIFJ Homework Equations I presume F=BIl and E=Blu. The Attempt at a Solution Not very well. I don't really understand how to start the question so if I could get some nudges in the right direction that'd be great. I'm not sure how...
2. ### Engineering DC Circuit Analysis & Thevenin Problem

Sorry for the late reply but just letting you know I figured it out. It's actually very straightforward and I was just overcomplicating it for myself (as usual). Thanks for your help!
3. ### Engineering DC Circuit Analysis & Thevenin Problem

Ok thanks. I tried that and I got a p.d. across R2 of 9V which I used as a "new" power source for the 2nd loop. After doing the 2nd loop, I ended up with 5V as my Thevenin voltage. Is that right?
4. ### Engineering DC Circuit Analysis & Thevenin Problem

Homework Statement Need to establish a Thevenin equivalent for the circuit attached. Homework Equations None given. Need to use Kirchhoff. The Attempt at a Solution I worked out the following: I said that R3 and R4 are in series as there is no current splitting because 0A...
