Critical Analysis On the Decay of the Art of Lying by Mark Twain “Lying is universal – we all do it.” In the essay‚ the author believes that all men lie because we must lie. There are many instances wherein men were prompted to lie at some point of their lives for the benefit of others. According to him‚ it’s better to give a good lie than a destructive truth. Lying for other’s advantage was given precedence than telling the truth at all times no matter how it hurts. Unfortunately‚ lying

RADIATION DETECTION IN VEGETABLE LEAVES: A COMPARATIVE CASE STUDY IN COASTAL AND HINTERLAND REGIONS OF AKWA IBOM STATE BY Godfrey T. Akpabio‚ Ime E. Essien And Bassey E. Bassey. Department of Physics‚ University of Uyo‚ Uyo. ABSTRACT Radioactive radiation level was detected for five samples of vegetable leaves namely: Water leaf‚ Fluted Pumpkin‚ Editan Lasientera africana and Afang Gnetum africanum. These vegetable leaves were collected from Uyo (interland region) and Ibeno

Uranium is a naturally occurring and abundant radionuclide with a half-life of approximately 4.5 billion years. Since uranium is an unstable element‚ it decays by ejecting alpha particles in order to become stable. Through this decay process radon and other radioisotopes are produced‚ however this paper will focus on radon and its prodigies. Radon is an alpha particle with a half-life of 3.8 days‚ and it has minimal potential for damage outside

Nuclear Energy There are many advantages and disadvantages of using nuclear power. Nuclear power is said to prevent power outages that happen in areas without nuclear power. For an example‚ if we were using hydroelectricity and the dam suddenly malfunctions‚ then we won’t have electricity until someone fixes the dam‚ and that would be difficult if it happened in the middle of the night. However‚ on the other hand‚ nuclear power is also considered toxic and it pollutes the Earth with harmful and

Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles (ionizing radiation). There are many different types of radioactive decay (see table below). A decay‚ or loss of energy‚ results when an atom with one type of nucleus‚ called the parent radionuclide‚ transforms to an atom with a nucleus in a different state‚ or to a different nucleus containing different numbers of protons and neutrons. Either of these products is named the

elements‚ oldest star clusters‚ as well as white dwarf stars. Scientists also try to find the universes rate of expansion‚ and behavior of globular clusters‚ which are spherical collection of stars. In order to find this‚ scientists can use radioactive decay to determine how old a given mixture of atoms is in rock samples. In order to find the rate of expansion of the universe‚ The Hubble constant was the basic cosmological model dependent on density and composition of the universe. Some formulas used
