A coiled telephone cord forms a spiral with 69.0 turns, a diameter of 1.30 cm, and an unstretched length of 46.5 cm. Determine the inductance of one conductor in the unstretched cord.]

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
