Suppose you are an engineer, and you are asked to measure the force on a supporting beam of a bridge. you measure it to be 50,067 lbs, but you know that your scale is only precise to ±400 lbs. how do you record this measurement in your final report to the client? (keep in mind that you want to find the perfect way to express the number to give an idea of how precise it is.) click the above link to submit a three sentence description, which includes:

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight 

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. 

Ibelieve the answer is d. densityhope my answer has you : )
