Essays on Nuclear Fusion

Gravitational, electromagnetic, strong and weak nuclear forces. Gravitational force is an attraction between any two pieces of matter in the universe. Electromagnetic force is present in pieces of matter, which are able to carry electrical charge. Strong force is holding the nuclei of atoms together. Weak force is responsible for radioactive decay. Molecules are built from the atoms and atoms consist of protons, neutrons and electrons. Protons and neutrons are built of smaller particles called quarks. Electromagnetic spectrum is the range of all the light in the universe. Depending on the wavelength and frequency there are radio, micro, infrared, ...

Re: extended definition of solar power and nuclear power

Purpose This memo is an extended definition of solar power and nuclear power as sources of energy. Introduction Solar power is energy from the sun. This energy is harnessed by collecting sunlight and converting it to electricity (Winter et al. 4). The cells found in the solar panels make this conversion possible. The conversion of sunlight to electricity can either be done indirectly by the use of a concentrated solar panel or directly by use of the photovoltaic cell. Nuclear power, on the other hand, utilizes nuclear reactions to produce nuclear energy (Murray 495). This energy is found in ...

Assignment 4

4. Describe the three (3) main layers of the Sun's interior. The three (3) main layers of the Sun’s interior are the Core, Radiation Zone, and Convection Core. First, the Sun’s Core or innermost part, is tightly packed and with a temperature of about 1.5x107 K. It extends from the Sun’s center to the photosphere (that is, approximately 0.25 solar radius or 1.75x105 km). It is at the Sun’s Core that thermonuclear reactions occur because of the enormous temperature and pressures. Second, the Sun’s Radiation Zone or the middle interior part, where energy ...

Q1. Describe the three main layers of the Sun’s interior.

The three main layers of the Sun’s interior are the core, the radiative envelope and the connective envelope.

The core is the center of the Sun, with a density of 150 g/cc and a temperature of 15 million K. This is the region where high energy fusion reactions take place and energy is produced. The energy produced is mainly in the form neutrino and gamma rays, which are actually high energy protons which travel several light years and supply energy to the Earth and other planets. The energy produced in the core then radiates outwards through the radiative zone. The ...

The variability of stars existing within our universe represents diversity and uniqueness. Humanity may not observe the whole life of a single star, however, techniques have been proposed to study the stars. We have different ways how to measure a star's temperature, age, and mass even, even though it seems impossible. The said variability of stars is key to the measurement of a star's characteristics. The existence of variable stars suggests that stars change on a time interval, unfortunately, too long humanity cannot observe. Nevertheless, humanity have developed a way of understanding the stars through their variability. Needless to say, variability provides unique ...

MEM 695

Abstract The purpose of this research paper is to introduce the different types of energy resources utilized worldwide. This paper discusses the history of the different resources used, starting with the utilization of conventional fossil fuel based technologies, the emergence of nuclear power and finally, the commercialization of renewable energy resources. The main objective of this research paper is to provide an insight on how these energy sources are accessed, utilized, distributed and developed. The paper also seeks to impact of the utilization of these various energy resources on the environment, especially the effect of continued utilization of ...

The Sun has been with us for 4 billion years, and is the nearest star to the Earth. The Sun is comprised of about 74% of hydrogen, 25% of helium, and 1% of other elements. The surface of the Sun has a temperature of about 5800 K. The core of the Sun has a temperature ranging from 10 – 15 million Kelvin. This temperature range is high enough to activate nuclear fusion within the Sun. Here, four protons will fuse together to obtain a helium nucleus containing two protons and two neutrons via a proton-proton chain. The core of the ...

The sun is about 864000 miles wide and filled with sweltering hot gases. Hydrogen is the most abundant element present in the Sun, composition of the Sun by its constituent mass is 71% hydrogen (H), 27% helium (He) and 2% other heavier elements. Inside the Sun the gravitational pull compresses the gases, and increase the temperature and pressure at the core. (CAIN, F., 2009) The temperature is about 10000°F on the surface and more than 28 million degrees Fahrenheit at the core of the sun. The pressure at the core of the sun is 250 billion times the ...

Global warming has been a major climatic concern for a couple of decades. Many countries suffer from this menace either extremely or mildly. The effects of global warming is evident in agriculture, whereby crops do not thrive well as a result of it, and also affects the human population due to its numerous effects on human beings. This paper is going to focus on the cause as well as the effects of global warming and other fuel use in the UAE.

Causes of Global warming

There are many things that bring about global warming. They include; Emission of carbon dioxide gas by plants that use fossil ...

Blue supergiant stars are staller evolutions that have resulted over millions of years. Stars during the main sequence phase spend a majority of their lives. During the main sequence stage, the star converts hydrogen to helium by nuclear fusion in the cores of stars the process also known as proton-proton chain. After spending of hydrogen fuel, the star will collapse and heat up rapidly causing the outer layers to expand inwards. When the core is very hot, the energy spreads through the interior of the star’s large surface area. The different fusion rates of different elements vary wildly to ...

Nuclear energy is a clean source of energy because it does not emit green house gas. Nuclear power plant produces energy like any other steam-electric power plant; but in nuclear power plant, source of heat to boil water is chain reaction due to nuclear fission of Uranium rather than using coal, oil or fossil fuel. Nuclear reaction is of two types- Nuclear Fission and Nuclear Fusion. Nuclear Fusion produces more heat than Nuclear Fission. So, there are possibilities of using Nuclear Fusion for the eventual generation of electrical power. But Fusion cannot be controlled and a perfected nuclear reactor has not ...

Nuclear power also known as nuclear energy is created by nuclear fusion for purposes generating electricity and heat. Uranium is used as fuel by the nuclear power plant. This is because uranium is a highly effective energy source compared to gas or coal. Nuclear fusions, this is when the uranium is combined with the free neutrons releasing heat and breaking down into light elements. The uranium is intensely radioactive thus considered highly dangerous but when put in the nuclear power systems the radioactive is reduced thus becoming less dangerous. The nucleus power plant began in the early 20th century because ...

Future Energy

Introduction The increasing quest for renewable sources of energy has greatly influence perception and appreciation of the benefits that could be derived from solar energy. Although the use of solar power as a form of energy to generate electrical energy is not a new technology, majority are yet to be aware of the benefits of using such forms of energy to both health and environment. It uses date back to ancient times where people make use of the energy to achieve their daily task i.e. drying purposes. The issue with the energy from sun could be associated with the challenges ...

For far too long, humanity has been content with unquestioned faith in subjective knowledge passed down from generation to generation. This has been especially true on issues regarding the origins of our species and, indeed, the universe. However, in the last 100 years, a new culture has emerged. A culture rooted in the ideals espoused by such trailblazers as Bertrand Russell; a belief in scientific understanding of the world we live in and veneration of acquisition of knowledge. The human race is no longer content with fables and fairy tales. We want to know how, when and why our universe came ...
