We have often used 2-dimensional solutions to laplace's equation (v"v = 0) for problems with a symmetry which prevents a dependence on the third dimension. construct an example where the solution depends on two coordinate variables, and explain why this is useful in electrostatics or magnetostatics. your example need only apply to either electrostatics or magnetostatics. it need not apply to both. 3.

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.
