If mass A and B are both 2.5 kg, the fulcrum is located 1.0 m to the right, mass B is located at 2.0 m to the right, and the bar has a mass of 4.0 kg, where must mass A be located on the bar in order for the initial torque to be 0.0 Nm?
a. 0.6 m to the left of the fulcrum
C. 0.6 m to the right of the fulcrum
b. directly above the fulcrum

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.
