The hubble space telescope is a reflecting telescope that was placed in orbit above the earth’s atmosphere, so its resolution would not be limited by turbulence in the atmosphere. its objective diameter is 2.4 m. for visible light, say λ = 550 nm, estimate the improvement in resolution the hubble offers over earth-bound telescopes, which are limited in resolution by movement of the earth’s atmosphere to about half an arc second. (each degree is divided to 60 minutes each containing 60 seconds, so 1◦ = 3600 arc seconds).

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.
