- Case a<r<b : your dA is πr^2 but when you rearrange for E your denominator is 2πε0r^2 where did the 2 come from ? Thanks :)2.15. In a hexagonal unit cell, indicate the following planes and direc- tions: (1210), (1012), (1011), [110], [111], and [021].Two infinite sheets of current flow parallel to the y-z plane as shown. The sheets are equally spaced from the origin by x = 6.1 cm. Each sheet consists of an infinite array of wires with a density n = 15 wires/cm. Each wire in the left sheet carries a current l₁ = 3.3 A in the negative z- direction. Each wire in the right sheet carries a current 1₂ = 4 A in the positive z-direction. R 1₁ H P % % OOOO OOO S X
- 21) Let ⃗A=6^i−8^j, ⃗B=−8^i+3^j, and ⃗C=26^i+19^j. If a⃗A+b⃗B+⃗C=0, calculate the variables a and b.Show that(3) The natural independent variables for U are (S, V), from dU = TdS – pdV. U = U(S,V) (), instead. Show that U = U (V,T) leads to a much more complicated expression for p, namely gives simple expressions for T and p as T = and ().: Suppose you use (V,T) p = - V dT + f(V), %D T where f (V) is an unknown function of V.

Where did they get x from?Let n 1 be an integer, let to to is given by a stationary path of the Lagrangian functional C: L[x] = 1 dt L(t,x,x), x(0) =x0, x(t)=X1, where LT - V and T is the total kinetic energy T = n 1 k=1 2 mark. Using the above first-integral, show that, if V is independent of t, the total energy E=T+V of the particle is a constant of the motion.
