1.A 300-g mass hangs at the end of a string. A second string hangs from the bottom of that mass and supports a 900-g mass. (a) Find the tension in each string when the masses are accelerating upward at 0.700 m/s2. (b) Find the tension in each string when the acceleration is 0.700 m/s2?​

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.
