On August 6‚ 1945‚ the United States of America dropped an atomic bomb on Hiroshima‚ Japan. The United States was justified to do this because of the unprovoked attack and bombing of Pearl Harbor‚ Hawaii‚ which occurred three years prior to the bombing of Hiroshima‚ and it was necessary to stop the war because it saved thousands of American lives. Until then‚ the fight had never been on United States soil. The innocent civilians of Japan did not have to worry about being killed on their land until

Donneida Thomas December 12‚ 2013 Physics pd. 11 Bombing of Innocent Civilians The former president‚ Harry Truman had to make one of the most crucial decisions of his life. On August 6‚ 1945 during World War II‚ he decided to drop the atomic bomb on two cities in Japan. The first bomb that dropped on Hiroshima was nicknamed “Little Boy”. The explosion wiped out 90 percent of the Hiroshima and immediately killed an estimation of 80‚000 people; thousands more people would later die of radiation

Atomic weapons are similar to poison gas – both are barbaric.The U.S.A. should not shock the world with such a weapon. What we have to understand is that current bombing campaign against Japan has brought the country just about to its knees. The atomic bomb will

Isotopes‚ sub-atomic particles and relative atomic mass Sub-atomic particles A subatomic particle is a particle smaller than an atom: it may be elementary or composite. In 1905‚ Albert Einstein demonstrated the physical reality of the photons‚ hypothesized by Max Planck in 1900‚ in order to solve the problem of black body radiation in thermodynamics. In 1874‚ G. Johnstone Stoney postulated a minimum unit of electrical charge‚ for which he suggested the name electron in 1891. In 1897‚ J. J. Thomson confirmed

ATOMIC THEORIES AND HISTORY * Democritus (Greek) - “atomus” meaning indivicible * Indivisible particles called atoms * John Dalton – MODERN ATOMIC THEORY: 1. All matter is made of tiny‚ indestructible particles called atoms (Democritus) 2. All atoms of a given element are identical (not accepted today bc isotopes) 3. Atoms are neither created nor destroyed in chemical reactions (Lavoisier) 4. Atoms of different elements form compounds in whole number ratios (Proust)

Composition II “You Have Atomic Bombs‚ but We Have Suicide Bombers” In Rohde’s article we learn of his experience as a hostage in Afghanistan and Pakistan. He explains the Islamic cultures and values‚ but shows us his view on them. Their cultures have some similarities‚ but more differences. We both have religions‚ but Americans approach their religion differently and less violently. America’s whole reality and country differs greatly from the Taliban’s society. The Taliban’s reality differs

1. a) Democritus reasoned that if matter could be infinitely divided‚ it was also subject to complete disintegration from which it can never be put back together. However‚ matter can be reintegrated. b) In Greek‚ the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos‚ a Greek word meaning uncuttable. All matter is composed of atoms‚ which are bits of matter too small to be seen. These atoms CANNOT be further split into smaller portions. 2. At

Radon IP-definición Radon gas is a radioactive gas that occurs naturally in the environment‚ mainly in the soil. It is present in uranium rich rocks and escapes into the air through cracks in the rocks. It is colorless‚ odorless‚ and tasteless. IP- descripcion funcion Radon can be a potential health hazard if it seeps in large amounts into your house. Long-term exposure to Radon can lead to cancer. (IS-comparación) Smokers face higher health risks than non-smokers from Radon contamination. (IS-contraste)

Carbon Emission and it’s Issues Recently‚ the amount of carbon emissions reached 40 billion tons. This is a record high‚ and is very damaging for Earth and humans alike. Carbon emission is a serious issue that can affect all of us in the near future. It is very harmful to the environment‚ but can also be delayed. Carbon emission is the total amount of carbon dioxide that are released in the air. There are natural and unnatural reasons for this. Nature‚ releases carbon dioxide‚ one of the most common
