A circular loop ( radius = 0.5 m) carries a current of 3.0 A and has unit normal vector of (2i - j + 2k)/3 what is x component of the torque on this loop when it is placed in a uniform magnetic field of (2i - 6j) T

How many atoms of nitrogen are in the chemical formula ni(w on

Convection currents are caused by differences in what two things?

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).
