Atransistor with a height of 0.4 cm and a diameter of 0.6 cm is mounted on a circuit board. the transistor is cooled by air flowing over it with an average heat transfer coefficient of 30 w/m2-°c. if the air temperature is 55 °c and the transistor case temperature is not to exceed 70 °c, determine the amount of power this transistor can dissipate safely. disregard any heat transfer from the transistor base.

Hahahah jsu’s hsjshshsh. shjshshshsh.

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. 

None. nothing. zero. zilch.
