having a known system of planets with life on one of its planets‚ called earth. The sun is not a solid body. It consists mostly of hydrogen gas. In the centre of the sun‚ hydrogen atoms are continuously combining to produce atoms of helium. Each time an atom of helium is formed‚ tremendous amount of energy is released in the form of heat and light. It is this energy which makes the sun shine. The planets and other objects in the sky reflect a part of the sunlight falling on them due to which they

It has a very weak magnetic field and – being the closest planet to the Sun – has only a very thin atmosphere of helium captured from the solar wind. Venus – Venus is named after the Roman goddess of love. It is the second planet from the Sun and the brightest object in the sky other than the Sun and the Moort. Venus has the most hostile environment in the entire

atomic nuclei named Helium. In this process‚ immense amount of energy is released‚ because the resultant nuclei release energy to a large extent to make itself stable. The real life example for Fission is supernova (explosion of a star)‚ and for Fusion is Helium gas formation on Sun. The mass change in the process is the source of nuclear energy. Fusion within the cores of the sun and other stars generates their radiating energy by fusing two hydrogen atoms to produce a helium

Our Advanced Planning Section has been examining some unusual projected problems and requests your assistance on the particular one described below. Decades from now‚ the present method of supplying energy to households (i.e.‚ with electricity‚ gas‚ or o11) may not be possible. Instead‚ housepersons will shop for their energy in supermarkets (Figure

Astronomy/Origins 2B03 “The Big Questions” Lecture #34 What makes a particle “elementary” ? • A particle is elementary if it has no inner structure (i.e not “made” of some even smaller entities). Quarks and leptons are the most elementary particles we know about at this time. They are no larger than 10-18 [cm] The Standard Model • Quarks and leptons are the most fundamental particles of nature that we know about. • Up & down quarks and electrons make up ordinary matter.

Mercury Mercury is called after the messenger of the Roman Gods. Mercury is 0.39 AU from the Sun. Mercury is 0.61 AU from the Earth. Mercury is quite a small planet. Its diameter‚ the distance right round its middle‚ is only 3‚031 miles or 4‚878 kilometres. Mercury’s average orbital speed is 48 km/s. Its orbit of the Sun lasts for only 87.96 days. Mercury only turns very slowly on its axis‚ taking 58.64 days to complete the turn from day to night. Mercury has an extremely thin atmosphere around

Although researching extremes was part of the program’s goals‚ setting records wasn’t the mission’s purpose. Joe ascended in helium balloon launched from the back of a truck. He wore a pressurized suit on the way up in an open‚ unpressurized gondola. Scientific data captured from Joe’s jump was shared with U.S. research personnel for development of the space program.

Chris Pauley Ernest Rutherford was a New Zealand physicist and chemist who earned the title “Father of Nuclear Physics” after his discoveries of radioactive half-lives‚ differentiated between alpha and beta radiation‚ and proved that radioactivity involved the transmutation of one chemical element to another. He is also the recipient of the 1908 Nobel Prize in Chemistry "for his investigations into the disintegration of the elements‚ and the chemistry of radioactive substances". Ernest

Period 1 only has 2 elements in it: Hydrogen and helium. Period 2 and 3 both have 8 lements. Other periods are usually longer. A colomn of elements down the table is called a group. There are 18 groups in the periodic table. Each group has a number from 1 till 18. Elements in a group are usually catorized
