The total resistance in a circuit with two parallel resistors is 2 ohms and R1 is 6 ohms. Using the equation for Rz, in terms of Rt and R2, what is R2?
R2 is
ohms.

Let u = {q, r, s, t, u, v, w, x, y, z} a = {q, s, u, w, y} b = {q, s, y, z} c = {v, w, x, y, z}. list the elements in the set. a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}
