A circuit(attached picture visualizing it) has a 10v source and two parallel paths in the circuitry. One
path has a pair of resistors of 20 and 30 Ohm
capacity in series- the other path has a single 50
Ohm Resistor. What is the total resistance
through the circuit, and what is the current
(amps) through each of the parallel paths.

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Transfer of electrons. hope it !

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.
