what find t? it is correct: t = -ln(0.25)*RC ? and what shuld be R?

Q2 e) : W(c) = W(l) |=> (q^2)/(2C) = (L*(I^2))/2 |=> q = sqrt[C*L*(I^2)]

Q2 (f): t = (pi*sqrt(LC))/2

Q3 (e), (d): (Q_0*(1+t/T)*I*d)/(pi*(R^2)*E_0), E_0 = 8.85 * 10^(-12) I = Q_0/T

t=-ln(0.25)*2*R*C -this formula at me isn't accepted

FLu, at me so: Q2: a) B = mu_0*I*N/(l), here l = length b) L = mu_0*((N/L)^2)*V, V = (pi*R^2)*d c) I = V/R D) U = (L*I^2)/2

length (l);

Io, The formula Q1 d)t=-ln(0.25)*2*R*C doesn't work for me, you can check it, there can be there a mistake is?

Sor! tomorrow I will explain

FLu, b) I think it`s rigth, but in formula mu_0*((N/L)^2)*V, value V is volume = (circle area) * (length solenoid), d=length, pi*R*R = circle. I have V = pi*0.001*0.001*0.14 = 4.39822971503e-07 R = radius = 0.1sm = 0.001m d = length = 14sm = 0.14m L = 1.2...

hmmmm, you me certainly forgive, but you are a little fool mu_0*((N/L)^2)*pi*(R^2)*d equally mu_0*A*N^2)/L
