The diagram below shows the relationship between the volume v of a gas in a constant pressure gas thermometer and the corresponding temperature on an arbitrary T scale, calibrated in ° P A) Determine the thermometric function for that device

B) Determine the temperature indicated by the device in ° P, when the gas volume is 1440ml

C) For a temperature of 1350 ° P, determine the new gas volume

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )

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. 

Since the pully is a simple machine so the mechanical advantage is a 1
