In order for a dilute magnetic alloy to show the kondo effect (resistance minimum at low T), the magnetic impurites must be far apart and non-interacting. In the Kondo lattice, the magnetic impurities are much closer togeather (one impurity per unit cell), so why does this system show the...

If two objects of equal mass are dropped...one from h1 and the other fro h2...will they hit the ground with the same force? Because the only force acting on the objects is gravity so we can say: F=ma and the acceleration is constant...so the forces must be the same. Is this correct...

Hello everyone, I am an undergratude student doing to research and I am making dirty Au films. At certian concentrations of Fe (say >.5%) this Au-Fe is showing charateristics of a sping glass. I am attempting to learn what exactly a spin glass is and what its trends look like (resistance vs...

i need help coming up with a way to solve for the eigen vectors of schrodinger's time independant equation in c++. so i want to write a class that uses the shooting method, but i am not sure how to do that.

right it is the first value...i don't have the notation for that in my keypad... but the when i do that operation =2.37x10^5 N m^2/C which is wrong

well the net charge inside is just 2.1x10^-6 C/e is that right?

that means that the flux= the charge on the inside of the soild/ the constant e which is 8.85 x10^-12

ohh that's right...ok so now if i calcuate what E is E=Kq/r^2 now r is at the the center of the cube so r=.064/2 E=(8.99x10^9)(2.1x10^-6)/.032^2=1.84x10^7 A=.064*.064=.004096 now 1/6flux=(1.84x10^7)(.004096) flux=4.53x10^5...but that still isn't the right answer help me please

A 2.10- mC charge is placed at the center of a cube of sides 6.40 cm. Determine the electric flux through each of the sides. ok so electric flux=E(A) so i figure that the electic flux will be the same for all six sides of the cube so i am just calculating the flux on one side then X6...

thank you very much

ohhh ok...i think i understand.. so if i have (2x+3)/(x+1)^2=(A/x+1)+(B/(x+1)^2) (*) then 2x+3=A(x+1)+B because i multiply both sides by (x+1)^2

so should it be 2x+3/(x+1)(x+1)=(A/x+1)+(B/x+1) here..i just split up the (x+1)^2 this is right?

what happened to to (x+1)^2 term?

(2x+3)/(x+1)^2 so this is what i am thinking...but it does not make sense =(A/x+1)+(B/(x+1)^2) so then 2x+3=A(x+1)^2+B(x+1) 2x+3=Ax^2+A2x+A+Bx+1 so that would make... 0=A 2=2A+B 3=A+B this solution does not make any sense becuase if A=0 then according to the second...

ummm...so do i have to find in they x and y compnents and all that sutff?
