Avertical electric field of magnitude 2.00 x 10^4 n/c exists above the earth’s surface on a day when a thunderstorm is brewing. a car with a rectangular size of 6.00 m by 3.00 m is traveling along a dry ravel roadway sloping downward at 10.00. determine the electric flux through the bottom of the car in the unit kn m2/c.

The answer to this is decibel

I'll do it rn and then answer

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.
