Homework Statement We did a lab where we measured the magnetic field strength of a wire coil versus the coil density of the wire coil, keeping current constant. We determined the relationship of B (magnetic field strength) versus n (coil density) to be direct. I need to explain why this is...

Am I correct in thinking that it would not matter if I place the 100ohm resistor after the 220nF capacitor (as shown in the picture), or before the capacitor?

Nevermind, I figured out that it should instead be just: a=v^2/r 6(9.8)=108.333^2/r r=199.592

Ok so I have solved (a) with a solution of 3430 N, thanks. I'm still having problems with (b) though. 390 km/h = 108.333 m/s 3430=(50(108.333^2))/r r=171.079 This isn't the correct answer apparently (I put in my answer into an online form and it tells me if it's right or wrong).

Homework Statement A pilot of mass 50 kg comes out of a vertical dive in a circular arc such that her upward acceleration is 6g. (a) What is the magnitude of the force exerted by the airplane seat on the pilot at the bottom of the arc? (b) If the speed of the plane is 390 km/h, what...
