Here's the cbse syllabus for magnetic effects of electric current

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. 

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .

There are no answer choices, so an example would be: it takes a long time and a lot of precision to sew a shirt by hand, so a machine was created to do the job instead.
