Consider a meter stick pivoted about the center of mass. If one hangs a 0.4 kg mass at the 0.8 m mark, which mark on the stick must one hang a 0.3 kg mass to balance the system?

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.
