Global positioning system (GPS) The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites that orbit the earth at approximately 12‚000 miles above surface and make two complete orbits every 24 hours. Placed into orbit by the U.S. Department of Defense the GPS was originally intended for military applications‚ but in the 1980s‚ the government made the system available for civilian use. GPS works in any weather conditions‚ anywhere in the world

Properties of transition metals strongly depends on the number of d electrons! Cohesive energy Bulk modulus. Melting temperatures and elastic constant follow the same pattern. The behavior reflects the strength of the d-orbital interactions. Rare Earth Metals. f-orbitals are localized and interaction between forbitals of different atoms is weak. Most of the RE metals are trivalent (exception Ce4+‚ Sm2+‚ Eu2+). Most

MOLECULAR ELECTRONICS INTRODUCTION Molecular electronics (sometimes called moletronics) is a branch of applied physics which aims at using molecules as passive (e.g. resistive wires) or active (e.g. transistors) electronic components. The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by such minute components. It is an enticing alternative to extend Moore’s Law beyond the

6100 meters. Fault- a break or fracture in the surface of the moon along which movement has occurred Apollo 11‚ 12‚ 15‚ 16‚ and 17 landed on moon. The moon revolves eastward around Earth in an elliptical orbit. Its orbital plane is tilted 5 degrees with respect to Earth’s orbital plane. The 5 degree tilt allows the it to be overhead at any latitude between 28.5 deg. North and 28.5 deg. South latitude. Two different lunar months: Sidereal month- 27.33 days. It is the time for the moon to turn

PHYSICAL PROPERTIES OF THE PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. A quick summary of the trends The oxides The oxides we’ll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O

is made of. 6)Electrons in the Bohr theory are in perpetual motion‚ which says the electrons are constantly accelerating and decelerating. As the electrons are moving inward and outward they are moving through different energy levels‚ known as orbitals. In order to move through the different energy levels‚ electrons gain or lose energy to become like it noble gas representative. They gain energy through heat or through collisions‚ and they lose energy by emitting light. 7)“Spectral lines are
