Consider a solid cube with a side whose measurement is l and a solid cylinder of diameter d and length h. the cube and cylinder are made of the same material and each generates the same amount of heat. if l-d h, use calculations to determine and state which one, (the cube or the cylinder) that should have a higher heat generation rate

No bc a lot of things r still theories n unproven

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. 

B) erini just took the test and it is correct
