I attached the problem with this post. I know Keq= Products/Reactants Is that what I would have to do here? Treat T as products and R as reactants?

Fnet = ma + ILBsintheta but I don't know B

I need to see an equation, I don't understand with just talking about it

Im completely lost, I thought we said F=0

gravity? I am just not sure where this is going.

I have no idea

the magnetic force?

Okay, so that would make F=0... so how do I get current?

Okay, since the second wire is floating the acceleration is 9.8m/s2 which means the net force would be F=ma=20*9.8=196N Would I set B1 = B2?

A wire of length 2m and mass 20g is help horizontally. It has a current running through it. You have a second identical 2m long wire that you want to "float" 1cm below this wire. a. How much current would you need in each wire (assume you have the same current through both wires) and in what...

Someone please help! So far I have F=ILBsintheta F= (4.6)(25)(.24)sintheta I can not figure out theta :cry::confused:

I have the same problem, but with different numbers... "The x, y, and z components of a magnetic field are Bx = 0.12 T, By = 0.12 T, and Bz = 0.17 T. A 25 cm wire is oriented along the z axis and carries a current of 4.6 A. What is the magnitude of the magnetic force that acts on this wire?"...

so 900 minutes?

My teacher posted a practice exam with no answers so I want to make sure I am doing my problems right. A car battery is rated at 70 A-hrs. How many minutes can this battery last if it operates at a current of 15A? I made an equation 70A/60min = Xmin/15A So, X=17.5 min Am I right?
