Two long, parallel wires are separated by 2.0 cm. the current in one of the wires is three times the other current. if the magnitude of the force on a 2.0-m length of one of the wires is equal to 60 μn, what is the greater of the two currents?

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).
