We have succesfully obtain a two dimensional atomic array by a state of the art nanofabrication technique. the energy bandgap of this material is found to be 2ev and its fermi level is located 0.2ev below he conduction band minium. utilizing the mathmethical relations given below, find the concentration of electros which can contribute to the current conduction. assume that the fd distributioncan be approximated to mb distribution

You yeah with the side of the yeah with a little bit of yeah.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
