what exactly caused this point to become the universe we know today? The “big bang” theory is the popular explanation for where the galaxies‚ stars and planets came from. At the moment of the big bang‚ the hot‚ compact point began expanding like a balloon‚ rather than an actual explosion like most people believe. As the point of matter expanded‚ it cooled‚ contracted and formed stars and galaxies‚ like our solar system and the Milky Way. This suggests that big bang explains the expansion of space itself

and metal. They also generally have high densities‚ slow rotation‚ solid surfaces‚ no rings‚ and few satellites. These planets include Mercury‚ Venus‚ Earth‚ and Mars. On the other hand‚ the jovian planets are composed primarily of hydrogen and helium. They generally have low densities‚ rapid rotation‚ deep atmospheres‚ rings‚ and numerous satellites. These planets include Jupiter‚ Saturn‚ Uranus‚ and Neptune. The closest terrestrial planet to the sun is Mercury. Mercury is relatively small

electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching each other. Rub a balloon in sweater. Rub several times the balloon and the sweater so there is more attraction Bring the balloon as close to the wall as possible

deeper than you are likely to dive at. You will find watches here with ratings as high as 1000 meters for professional scuba diving. Some also feature helium release valves - a one-way pressure relief valve typically consisting of a strong spring‚ a plug‚ and a good rubber gasket. The helium valve prevents damage to the watch due to the buildup of helium gas in the watch after extended stays inside the dry pressurized habitats used for commercial diving.

Model of MacGregor.[10] Consistency between models[edit] Main article: Nuclear structure[->0] As with the case of superfluid[->1] liquid helium[->2]‚ atomic nuclei are an example of a state in which both (1) "ordinary" particle physical rules for volume and (2) non-intuitive quantum mechanical rules for a wave-like nature apply. In superfluid helium‚ the helium atoms have volume‚ and essentially "touch" each other‚ yet at the same time exhibit strange bulk properties‚ consistent with a Bose–Einstein

by nuclear fusion in their cores‚ mostly converting hydrogen into helium (Fusion in Stars‚ 2012). The production of new elements by nuclear reactions is called nucleosynthesis. A star ’s mass determines what type of nucleosynthesis occurs during explosive changes in its life cycles (Fusion in Stars‚ 2012). Nuclear Reactions The smallest stars only convert hydrogen into helium. Medium stars‚ such as our Sun‚ can convert helium into oxygen and carbon. Both small stars and medium stars are considered

Jeff Koons’ Balloon Dog (Yellow) This essay discusses the sculpture Balloon Dog (yellow) (1994-2000) by American artist Jeffrey Lynn Koons (b.1955). I will explain how Koons uses the Balloon Dog (yellow) to talk about both childhood experience and sexuality‚ and uses these ideas to manipulate the viewers’ emotion.

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

The article discusses the basic concepts of stars and some basic facts of astronomy the importance of the article that it shows how by using the spectroscopy technique we can determine the interaction between matter and radiated energy and discover that some objects give off and adsorb different spectrum of light. The article makes you understand the different stages of the lifecycle of the sun. Astronomers study light which comes from distant objects to determine its composition‚ temperature‚
