The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from

In Flannery O’Connor’s short story‚ the use of symbolism and foreshadowing is exquisite. The story starts off with a reluctant grandma who fears taking her family in the direction where a criminal who goes by “Misfit”‚ is loose. This is the first instance of foreshadowing that is given in the story. The grandma later goes on to announce how she would not be surprised if the Misfit attacked the place where they stopped to eat. Along with this also comes the conversation she has with the restaurant

Ch.9.1 – Types of Electric Charge * Static electricity : static cling of clothes out of dryer; lightning; * Walk across carpet and touch get a shock touching metal doorknob – friction of shoes against carpet cause you acquire static electric charge * Static charge – electric charge at rest‚ stays on and eventually discharged or lost to other objects/air * Discharge – remove excess static charge so the object is neutral * Static charge last long when air is dry * Electrostatics

Marybeth Brooks Physics Lab III Specific Heat Capacity Lab May 25‚ 2011 Abstract The specific heat capacity of various metals can be calculated and compared to accepted literature values. Dropping heated metal samples into a calorimeter filled with water and then measuring the change in the temperature of the system accomplished this. The metal samples were heated in a boiling water bath and were assumed to be at 100 C when they were removed. It was added to a calorimeter and stirrer

rational humans with those who have mental “incapacities‚” has been a long debate in ethics. If we were able to prove that animals and non-person humans have rational capacity‚ although different compared to persons‚ then these non-person beings might be given moral rights. Since humans usually use the supposedly unique rational capacity to justify their dominion over the other beings‚ then proving the rationality of non-person humans and animals could result to gaining basic respect for them from the

Electric Charge Lab John Doe Physics 1130 Oct 26th‚ 2010 Objective In this lab we will investigate some properties of electric charge‚ conductors‚ and insulators using everyday objects. Theory A charged object is any object that has an excess of negative or positive charge. Most objects are neutrally charged and we don’t normally experience their charge properties. Rubbing objects together and transferring some charge from one to the other is one way to create charged objects. Like charges

I. Introduction A buffer system is a mixture of a weak acid or a weak base and its salt (conjugate base or conjugate acid‚ respectively) that permits solutions to resist large changes in pH upon the addition of small amounts of hydrogen ions (H+) or hydroxide ions (OH-). If the same amount of the buffer is added‚ the pH may only change a fraction of a unit. Our blood is a good example of a buffered system. It is maintained under a pH of 7.4. Thus‚ buffers are important in many areas of chemistry

He was born in Somersby‚ Lincolnshire and he remains one of the most popular British poets In 1855‚ Tennyson produced one of his best known works‚ "The Charge of the Light Brigade"‚ a dramatic tribute to the British soldiers involved in a charge on 25 October 1854‚ during the Crimean War. Tennyson used a wide range of sources ranging from medieval legends to classical myths and from domestic situations to observations of nature‚ as part of the material for his poetry to give him ideas. The poem is
