A comet has been located orbiting the sun at an average distance from the sun of 28 AU and an eccentricty of 0.97. Calculate the perhelion distance of the comet and comment on whether or not the comet is a danger to Earth.

The answer will be d. reflects light because it cant be all the others because light cant be other things other than light

You would need to take a picture so i can see

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.
