Was the "Hindenburg disaster" a result of sabotage committed by the opponents of the Nazi organization? Did a bolt of lightning strike the zeppelin? Or was one of the most devastating accidents in aviation history nothing but a cunningly planned insurance fraud? <br> <br>Over 60 years ago‚ airships were the "queens of the skies." In the early 1900s‚ a stubborn‚ yet brilliant German count‚ Count Ferdinand von Zeppelin‚ took keen interest in balloon flights and was devoted to the design and construction

these stars have reduced numbers they still have distinguishing characteristics. These stars can go through different types of fusion than other stars‚ this allows the stars to still burn after all the hydrogen and helium have been used up. In this the high mass stars can create helium with hydrogen fusion‚ which means these stars can fuse large elements later in life. These stars also have an increased gravitational field‚ which produces the heat that starts the fusion. Fusion occurs more in a high

MAGNETIC MAGNETIC REFRIGERATION a fruitful approach to reduce environmental pollution... ABSTRACT : The objective of this effort is to determine the feasibility of designing‚ fabricating and testing a sensor cooler‚ which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magneto caloric effect‚ which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling

THEORIES OF THE ORIGIN OF THE UNIVERSE 1. Steady State Theory – based on the perfect cosmological principle that the universe looks the same from any location at anytime. This theory holds that the universe is unchanging‚ it has no beginning and no end. 2. Big Bang Theory – presupposes that the vast universe grew out of something where all matter and energy were compressed to infinite density and heated to trillions of degrees (a beginning which was an immensely small particle of high-density

the core of the disk that formed from the clump of gas that was compressed inside the gas cloud. The star becomes a stable main-sequence star‚ which are characterized by the source of their energy. They are all undergoing fusion of hydrogen into helium within their cores. The rate at which they do this and the amount of fuel available depends upon the mass of the star. Mass is the key factor in determining the lifespan of a main sequence star‚ its size and its luminosity. Stars on the main sequence

Lesson 3.01: History of the Periodic Table 1. Explain how scientific observations led to the development of‚ and changes to‚ the periodic table. Dmitri Mendeleev- first periodic table‚ organized 63 known elements according to properties‚ organized into rows and columns. He wrote names‚ mass and chemical properties on each. Julius lothar Meyer- independently worked in German ‚ similar to Mendeleev Henry Gwyn Jeffrey’s Moseley: worked with Ernest Rutherford experimented with 38 metals‚ he found that

1. What are the six regions of the Sun? The Sun’s regions are the core‚ the radiative zone‚ the convective zone‚ the visible surface‚ the chromospheres‚ and the corona. The core‚ radiative zone‚ and convective zone make up the interior of the Sun. The visible surface‚ chromosphere‚ and corona make up the exterior of the Sun. 2. What is nuclear fusion? What role does nuclear fusion play in the Sun? Nuclear fusion happens when two atomic nuclei combine to form one heavier nucleus. Since the majority

reaction where matter is forced together and the nuclei are fused together. This is how the first start was born when hydrogen atoms were fussed together to create helium. After this many more starts and a lot more elements were created. Stars start there life as a cloud of gas called a nebula. Mainly consisting of hydrogen and helium. The gases will then be drawn to a centre point of gravity which will then create a protostar. And then the nuclear fusion in the core of the star will star and the
