The benefits of space exploration are vital to our rapidly advancing world. One can say that the benefits resulted from space exploration can better ensure the safety and wellness of individuals‚ and to the well-being and survival of mankind‚ as there are useful spin-off technologies‚ sophisticated satellite technologies‚ and advanced space travelling technologies that can save human lives. I agree for the continuation of space exploration due to these benefits‚ as they greatly exceed any of the

atom’s electrons may jump to a higher energy level. The atom is then said to be excited. When an electron of an excited atom falls to a lower energy level‚ the atom may emit the electron’s excess energy in the form of a photon. The energy levels‚ or orbitals‚ of the atoms shown here have been greatly simplified to illustrate these absorption and

observations of‚" 2010) Kepler developed three laws of planetary motion. He stated that the orbits of the planets are elliptical‚ that the planets revolve around the Sun at different speeds‚ and that there is a proportional relation between a planet’s orbital period and its distance to the Sun. Galileo was a backer of Copernican theory. He constructed an astronomical telescope in 1609 and made several discoveries‚ some of which were sunspots‚ the features on the moon‚ and the different phases of Venus

Abstract Generally‚ when one hears the word psychopath they automatically think of someone who is cold and sinister a serial killer‚ pedophile an absolute monster. Perhaps‚ that’s due to the way they have been portrayed by the entertainment industry. Society fears and loathes these individuals‚ but are fascinated by them. Psychopathy has been studied for decades‚ yet we still know little about the disorder. What is a psychopath‚ and how and where are they created?

The colors visible in the spectrum have different values of wavelengths. Electrons of atoms occupy specific orbital configuration for different energy levels. If the atoms are disturbed by an electromagnetic wave‚ the atoms absorb energy which is expressed as

Light Emission and Absorption - Active Reading When atoms absorb energy‚ electrons can jump to higher energy orbitals. When the electrons move back to their original configurations‚ that energy is given off as light! Travel to the website linked below and take Cornell notes for each section.

of any individual member of the system. The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space‚ such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics‚ the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest at with respect the

are some lines in a spectra easier to see and appear brighter? Some lines in a spectra are easier to see and appear brighter because when there is a brighter spectral line‚ it means there is a large amount of electrons doing the same transitions in orbital when there are some lines in a spectra that is harder to see‚ it means there is a small

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)
