<span>In general (according to Russia's early histories), the ancestors of Russian people were almost from the Pripet Marshes. It was a vast natural region from the wetlands. People or tribe from this place were called Slavic.Despite of many variety of people from several nations, the Slavic were the first people to settle in Russia and Ukraine. the answer is the choice B:slavics.</span>
Compute the structure factor for both the disordered and ordered states and determine which reflections are only present in the ordered state; these are known as superlattice reflections.
What is Superlattice Reflections?
A superlattice (SL) is a structure in which two different materials are grown in alternating layers to a specified thickness. home:
Nitride semiconductor light emitting diode (LED)
Therefore, Compute the structure factor for both the disordered and ordered states and determine which reflections are only present in the ordered state; these are known as superlattice reflections. Order and superlattice reflections: in the disordered state,Cu3aAuhas an fcc structure, with lattice parametera=0.3749Â nm. In the ordered state, Au occupies the corners of the cell, whereas the Cu atoms occupy the Gace centers. (Assume that the lattice parameter remains constant).

Absolutely true! With the invention of steam power, a new source of energy was formed, and in return paved the way for more machinery to be built using this power.
