2. A 0.02 kg ball spins in a horizontal circle of radius 0.50 m with a frequency of 4.0 Hz. What is the tension force in the string (the centripetal force on
the ball)?

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.
