Above the xy plane (z > 0), there exists a magnetic material with µr1 = 2.0 and a field h~ 1 = 3.0 ˆx + 4.0 ˆz a/m. below the plane (z < 0) is free space. (a) find h~ 2 , assuming the boundary is free of surface current. what angle does h~ 2 make with a normal to the surface? (b) find h~ 2 , assuming the boundary has a surface current k~ = 3.0 ˆx a/m.

Biased means unfair but that's all ik

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.
