Homework Statement A long, straight wire carrying a current of 4.00 A is placed along the axis of a cylinder of radius 0.500 m and a length of 3.00 m. Determine the total magnetic flux through the cylinder. Homework Equations Flux = BA B(long wire) = (((4 * pi) * 10^-7) * I )/ (2 * pi * R)...

Bump. Any idea on the F.minimum? Thanks, kyle

Ok, I figured out F.max by just saying: .5mv^2 = qV F.max = qvBHowever, I'm not sure what F.min is and the difference between F, F.max, and F.min?

An electron is accelerated through 2550 V from rest and then enters a region where there is a uniform 1.70 T magnetic field. What are the maximum and minimum magnitudes of the magnetic force acting on this electron? F = qvB F = (mv^2)/R F = qE I know q = 1.6*10^-19, B = 1.7, and V = 2550. In...

A metal wire has a resistance of 8.70 ohms at a temperature of 20°C. If the same wire has a resistance of 11.20 ohms at 90°C, what is the resistance of the wire when its temperature is -20°C? R = Ro[1 + a(T-To)] Basically what I did was found a first by using the 2 given resistances and...

Anyone able to assist with this one?

1. Capacitors C1 = 4.0 µF and C2 = 2.0 µF are charged as a series combination across a 95 V battery. The two capacitors are disconnected from the battery and from each other. They are then connected positive plate to positive plate and negative plate to negative plate. Calculate the resulting...
