Aproton, which moves perpendicular to a magnetic field of 1.35 t in a circular path of radius 0.072 m, has what speed? (qp = 1.6 · 10 19 c and mp = 1.67 · 10 27 kg)

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.
