To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. what kinetic energy, , must the electrons have in order to resolve a protein molecule that is 2.80 nm in diameter? take the mass of an electron to be 9.11×10−31 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.
