The minerals that make up rocks give them their unique properties. Based on Nguyen's results, do you think that any of the three rocks have the exact same mineral makeup, or are they three different types of rock? Explain your answer.

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

Ithink it is letter b, i may be wrong but i think that is the 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.
