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?

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. Write some big ideas in the left column and supporting details in the right column. Make sure to answer any questions given as well. Make sure you play and watch every animation and click every link

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)

are only in their excited for a brief moment. When the electron moves back down to a lower energy state‚ it emits light and produce a flame color.1 Sometimes there is more than one flame color because an electron might go from the 4s orbital then go to the 2p orbital which means two colors will be produced. Every element emits a different flame color or colors. These colors can be put on a bright line spectra which shows every color that the element produces in a

It was a dark and thunderous night when returning home from my girlfriend’s house in Westville. Most of the way had clearly lit streets‚ until I got to the junction of Buttercup Lane and Meadow Street. I had a choice of taking a short cut through my local park‚ or walking around it‚ which would add a further mile to my journey. It was getting late‚ so I decided to take the short cut. The park was always dark with little or no illumination‚ except for the light given from the moon and the stars.

pycnocline 4. What is the difference between longitudinal waves and transverse waves? (Ch. 8‚ Section “How do waves move?” 5. Describe circular orbital motion. d. The water itself doesn’t travel the whole distance‚ but the waveform does. As the wave travels‚ the water passes the energy along by moving in a circle called circular orbital motion. 6. How can you calculate wave speed? e. Wave Speed (S) = Wavelength (L) / Period (T) 7. What are shallow-water waves?

comprised of protons and neutrons while only 1 ounce of their being would be made of electrons. Both the protons and neutrons reside within the nucleus. Protons have a positive charge‚ neutrons have no charge; they are neutral. Electrons reside in orbitals around the nucleus and have a negative charge. Atomic number is derived from the number of protons in an atom. Example‚ Helium‚ (H) = 1. The number of protons in an element is constant (e.g.‚ H=1‚ Ur=92) but neutron number may vary‚ so mass number
