Nuclear weapons were first developed by the United States prior to the start of World War ll. The first and only times that nuclear weapons were used in battle was against Japan in 1945. The United States dropped two different style of nuclear weapons on two different Japanese cities. One bomb used plutonium while the other used uranium to create the explosions. The bombs were dropped on Hiroshima on August 6‚ 1945 and Nagasaki on August 9‚ 1945. Estimates of deaths within the four months after

Workers quickly learned that they would have to come together and form organizations in order to over power the industrial owners. The Knights of Labor (KOL) was the first large labor union to be established. Founded in 1869‚ the Knights sought to build an organization uniting workers of all races‚ genders‚ ethnicities‚ and occupations. They lobbied government

“Compare and contrast solar power with coal powered energy” Energy is an important factor in todays society‚ it is neccesary to power business‚ manufacturing and the transportation of goods and services all around the world. Solar powered energy is energy from the sun. This energy can be conerted into different energy like heat and electricity. Heat can be used to heat water or heat spaces‚ for example heating for houses‚ buildings or even swimming pools. Solar energy can be converted in two ways

PLANTS Plants in Our Daily Life A plant(also called green plants) is a multi-cellular living organism‚member of kingdom Plantae.It is at the base of the food web and are Autotrophs.Plants are considered as backbone of all life on Earth and essential resource for living oragnisms.Plants can be reffered as a factory which processes light into energy and manufactures food for it ownself as well as for other living things.Scientists have foundmore than 270‚000 spieces of plants They include a host of

In spring of 1989‚ two scientists by the name of Stanley Pons and Martin Fleischmann announced that they had found a way to create nuclear fusion in a relatively simple and cheap way. Superhot fusion is the process in which deuterium‚ a heavier form of hydrogen‚ is held within a magnetic field and heated to tens of millions of degrees. The nuclei of the atoms fuse‚ and heat energy is released. This kind of fusion happens in our solar system’s sun. This type of fusion is known to occur‚ but recreating

** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

Plants‚ also called green plants (Viridiplantae in Latin)‚ are living organisms of the kingdom Plantae including such multicellular groups as flowering plants‚ conifers‚ ferns and mosses‚ as well as‚ depending on definition‚ the green algae‚ but not red or brown seaweeds like kelp‚ nor fungi or bacteria. Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained in chloroplasts‚ which gives them their

Nuclear World If a nuclear bomb was dropped on your city‚ how would you survive? The blast from the fission bomb on Hiroshima‚ which weighed 30 kilotons‚ was equivalent to 12‚500 tons of TNT. Now‚ if this was dropped right outside your house‚ there would be no way of survival. But‚ one megaton hydrogen bomb is said to have 80 times the explosive intensity of the fission bomb detonated in 1945. The destructive force of the hydrogen bomb is near unimaginable. But first‚ let’s take a
