Exercises 1 What is the energy associated with the fifth orbit? b. Calculate the radius of Bohr's fifth orbit for a hydrogen atom.
2 A hydrogen atom makes a transition from the n = 3 level to the n = 2 level. What is the change in energy?
3 An electron is in the second excited orbit of hydrogen, corresponding to n = 3.
Find (a) the radius of the orbit and (b) the wavelength of the electron in this orbit.​

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.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
