high energy physics and nuclear physics

Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process of changing mass into energy produces..

When lighter nuclides fuse together to form a heavy nucleus in a process called nuclear fusion, energy is produced and mass is lost. For example, two atoms of heavy hydrogen may fuse together to form helium and a neutron: The sum of the exact masses of the helium atom and the..

Nuclear fusion is the phenomenon of fusing two or more lighter nuclei to form a single heavy nucleus. Example..

The process of splitting of a nucleus of a heavy atom into a number of light nuclei with the liberation of large amount of energy and two or three neutrons is called nuclear fission. Example: When U-235 is bombarded by a neutron it splits into barium, krypton and 2.5 neutrons pe..

>When a nucleus emits radiation it is said to decay. Rays from radioactive isotopes are dangerous to living things but are also useful in variety of ways. Exposure to large amounts of radiation is harmful to health. All radioactive materials should always be handled with care and kept inside lead b..

Heating Effect of Electric Current - Energy exists in various forms such as mechanical energy, heat energy, chemical energy, electrical energy, light energy and nuclear energy. According to the law of conservation of ..

. Scientists estimate that there are about 10 billion trillion stars in the universe. Stars are enormous objects. Even large stars look like tiny dots because they are so far away. The nearest star - other than the sun - is more than 40 million kilometers away. Stars differ greatly in colour and br..

Tidal Power - The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the t..
