A science teacher sets up a demonstration for her class. She turns on three electric hot plates. On each hot plate is a beaker of water. Between the hot plate and the beaker is a block of material: metal, granite, or glass. The blocks are all the same size. The water in the beaker
above the metal block boils first.
Why does the water in the beaker on the metal block boil first?
O A Metal lets out more heat than the other substances,
O B. Metal is a harder material than the other substances,
O c. Metal transfers heat faster than the other substances,
OD. Metal is better at reflecting heat than the other substances,

Is this a question of an answer

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.
