The direction of Earth's magnetic field in the northern hemisphere is downward and to the north. If an east-west wire moves from north to south, in which direction does the current flow? I have no idea how to approach this problem. It was on my physics test and I got it wrong and I'm doing...

The other values given in the question that aren't useful are meant for other questions. I just really wanted to know if 15-ohms was the answer. My physics teacher makes a lot of mistakes. Thank you guys!

So there is a parallel circuit with two resistors, R1 and R2, and an ammeter that are connected to a constant 30-volt source. The equivalent resistance of the circuit is 6.0-ohms. The resistance of R1 is 10.-ohms. The resistance of R2 is equal to a) 6.0 Ω b) 2.0 Ω c) 15 Ω d) 4.0 Ω...
