nuclei fuse to form helium nuclei is the source of solar energy of the sun. In this process‚ enormous amount of energy is released. REACTIONS IN THE SUN There are two different cycles of processes. One is the proton-proton chain or p-p chain. The other is the Carbon Cycle or CNO cycle (Carbon-Nitrogen-Oxygen) or sometimes Bethe- Weizsäcker-cycle. Proton-Proton chain: The proton–proton chain reaction is one of the fusion reactions in which four Hydrogen nuclei fuse into one Helium nucleus with the

Everything else like metals is about less than 2%. This changes as the Sun turns hydrogen into helium in its core. The radius of the giant star is 432‚288 miles‚ while the mass is 1.982 x 1030 kilograms. Atmosphere

Solar disruption theory was one of several theories that emerged before the 18th century concerning the formation of the solar system. Solar disruption theory states that the collision of the sun with another stars caused debris to be ejected from its mass and these debris eventually became the planets. This theory was later discarded for the nebula theory of solar system formation. However there are some scientists that propose that it has some merit. The big question up until the 18th century

Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

An atmosphere of helium would cause an organ pipe to have a higher pitch because the speed of sound is faster in helium‚ but since the pitch of a tuning fork has a set frequency‚ the pitch will not change. 3.

atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas. The sites of star formation in the galaxy are mostly located within molecular clouds – expansive‚ cool clouds of mostly hydrogen and helium gas. Molecular clouds are on average too diffuse to contract gravitationally‚ but within a cloud are regions of locally higher density‚ which are the sites of active star formation. It is not known exactly what causes molecular clouds and star-forming

Walt Whitman Whitman’s different views of writing Walt Whitman is one of the first great American poets. He was born in 1819 on Long Island and he was one of ten children. Whitman only went to school for a few years until he turned eleven and concluded formal schooling. He then attempted to find work to support his future family. He found a job as an office boy and then moved on to be an apprentice with a local paper where he learned all about the printing press. The following summer he joined
