X10 do you know how to solve for the magnetic field of a loop? i've been cracking my head

it has to be in meters I=J*w*s (w and s are in meters so change them) then B= (mu_0*(J*w*s))/(2*pi*w)*(ln(1+w/x)) all are in meters. should get something like a 6.++e-7

now someone please help me with this question A current I=2.9 A flows around a continuous path that consists of portions of two concentric circles of radii a and a/2, respectively, where a=4 cm, and two straight radial segments. The point P is at the comm...

Flu our values may vary so i am not certain. but the formulas are fine if you could assist me on Q5 Flu ?

I have only the Bx and By, I assume you have them? it is both 0 with mine. I could not figure Bz out yet but will let you know when I do.

sorry its supposed to be 6.++e-11 if you have your fx-570MS calculator you should be able to find mu_0 there. don't bother expanding the values

((1.256637061e-6)*(1*0.08*0.001))/(2*pi*0.08)*(ln(1+(0.08/0.22))

the brackets... BRACKETS ((1.25663706*10^-6*(1*0.08*0.001))/2*pi*0.08)*ln(1+(0.08/0.22)) = 3.91822*10^-12 ((1.25663706e-6)*(1*0.08*0.001))/(2*pi*0.08)*ln(1+(0.08/0.22))= 6.2030986e-11

magnetic loop is the only one i can't solve

need help on 2 RL circuits D:

i need help on the RL and RLC circuits :/

anyone can help me on the RL circuits?

can u help me on the RL circuit question 1 and 2?

please do help on this one

a)0.0126 b)1.63e10 c)1.46 , (E_0*n)/c d)... help

i think you meant b... did the rest of the answers work? the formula is c/v ; c=speed of light, v= speed of what you calculated in which it would be (1.03e11)/(5*100)

you're welcome. i need help with the remaining questions if you don't mind

oh btw k is 501.27

and omega is 1.03e11

flu i am stuck on the rest of them :/ you have some answers?

FLu, these are the following: Q3 (all) Q5 b) Q6 Q7 Q8 i know its a lot :S

my 1 f) are as follows: -1.17e-7 4.72 -1.01e9 2.81e-7 1.567 -3.62e8 the answers you provided for Q6 a regarding wavelength are wrong in my case though. i have a value of k=1e2 and omega= 3e10 also Q3 completely wrong (formulas provided will be appreciated...
