How much voltage must be used to accelerate a proton (radius 1.2×10−15m) so that it has sufficient energy to just "touch" a silicon nucleus? a silicon nucleus has a charge of +14e, and its radius is about 3.6×10−15m. assume the potential is that for point charges.

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.
