Complete the following two statements regarding quantum-mechanical concepts associated with the bohr model of the atom and refinements that resulted from the wave- mechanical atomic model.

two important quantum-mechanical concepts associated with the bohr model of the atom are that eledtrons are particles moving in orbitals, and electron energy is quantized into

two important refinements resulting from the wave-mechanical atomic model are that the electron position is described in terms of a and electron energy is quantized into both shells and subshells--each electron is characterized by quantum numbers.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

it doesn't. it was imagined up in the middle ages.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
