A physics student misspoke when he gave a presentation. He stated that the total energy of a substance is best demonstrated by its temperature. It would have been most correct for him to say that A. the total energy is demonstrated by the substance's specific heat.

B. the average kinetic energy is demonstrated by the substance's thermal energy.

C. the total kinetic energy is demonstrated by the substance's thermal energy.

D. the mass determines the substance's average kinetic energy.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.

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.
