While rebuilding the circuitry in her computer, Fabiola switches out a connecting conducting wire for a new one which is longer, has a higher resistivity, and has a larger cross-sectional area. What happens to the resistance of this connection? a. The resistance increases. b. The resistance decreases. c. The resistance remains the same. d. More information is needed.

The rocks expand when there hot/warm  and contract when they are cold.

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.
