A particle starts out from the origin with velocity 10ms^-1 and continues moving at the velocity for 5s. The velocity is then abruptly reversed to -5ms^-1 and the object moves at the velocity for 10s. For this motion find a. The change in position, i. e. displacement
B. the total distance travelled
C. Average speed
D. Average velocity

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.
