If the total momentum of a system is a constant, then we say that the total momentum is conserved. a consequence of newton’s laws of physics is that the total momentum of a system is conserved whenever the net external force on the system is zero. describe all the external forces acting on the carts during these collisions and explain what the net external force was. was it zero or approximately zero? was momentum conserved

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.
