I. The leaves of the electroscope open up when a positively or negatively charged rod is brought near its tip because of polarization. Polarization is not a permanent charge; we are not charging the electroscope. When we approach the electroscope with a negatively charged rod, the electrons in the electroscope rush down to the leaves. This is due to the fact that like charges repel. Now that both of the leaves are negatively charged, they will repel and therefore open up. When we approach the electroscope with a positively charged rod, the electrons are attracted to the rod and rush to the tip rather than the leaves of the electroscope. Protons are located in the nucleus, and therefore cannot move around. So, the leaves have a positive charge. Two like charges in the leaves, both leaves having a positive charge, causes the leaves to repel.








II. The electroscope can be used to store charge or charge another object through conduction and induction. For conduction, even after the rod is removed, the electroscope continues to have the same charge as the rod. When the rod touches the electroscope, electrons are transferred between the two, so that the electroscope has the same charge as the rod. Meanwhile, with the process of induction, the rod is brought near the electroscope but does not touch it. The rod and the electroscope will have opposite charges.







III. The electroscope can be used to test an unknown charge by observing the behavior of the leaves when the rod is brought near the electroscope. The electroscope first has to be charged by conduction or induction with a known charge. We would use either one of these processes to observe the behavior of the leaves. For conduction, the rod has to be charged and must touc...

...ged rod is brought near. This leaves one of the spheres with all of the electrons and the other sphere with all of the protons. The sphere with the electrons is negatively charged, while the sphere with the protons is positively charged. When the spheres are separated so that they are not touching, we have two differently charged systems.






XII. An object getting a positive charge is different from it getting a proton. Electrons are the only particle which can be transferred back and forth between objects. Protons are located in the nucleus of an atom, and cannot leave unless there is a nuclear reaction. Therefore, objects cannot gain or lose protons, but can gain or lose electrons. Objects can acquire a static electric charge by gaining or losing electrons. An object can acquire a positive charge by losing electrons, so that it has fewer electrons than protons.

Misconceptions Regarding the Magnetic and Electric Polarization Essay

- Polarization is the separation of the negative and positive charges within an atomic object, a nuclear, and a chemical system. Through induction, the movement of electrons within an object mixes. The system or the object is has an excess of the negative electrons concentrated on one side while the other side has a concentration of positive electrons. This leads to concentration of the opposite charges on different ends of the object (Askeland and Pradeep 116). This paper studies the misconceptions and the confusions regarding the magnetic and the electric polarization....   [tags: chemical systems, electrons, negative charge]

Social Polarisation in Global Cities: Theory and Evidence by Chris Hamnet

- Introduction. Throughout Gerring’s (2006) description of case selection techniques, the emphasis is set in the methodological structures of each procedure. Each of these techniques relies on certain parameters in which cases look for different means to representativeness. A case study should always be representative of a larger population and this stands a decisive benchmark for its validity as a stand-alone case, either for testing or generating a hypothesis (Gerring, 2006). The crucial case study however is presented with a more careful insight, since its methodological approach distances from the other techniques....   [tags: polarisation, ]

Physical Background Of Space Charge Essay

- Overview This chapter is divided in to two parts; the first part is reviewing the physical background of space charge, while the second part is reviewing some previous models that were proposed to calculate space charge under HVDC. Space charge One of the properties of insulation material under HVDC is their tendency to accumulate space charge; this is due to allowing weak electrical conduction by these materials [18]. The charges which are flow within insulation may be non-uniform due to non-homogeneity of the material [12]....   [tags: Electric charge, Fundamental physics concepts]

Essay on The Charge Of The Light Brigade

- We are often unaware of the cost of war on humans. We might calculate the numerical cost of weapons and equipments, but disregard the cost of cognitive, physical, and psychological on soldiers, civilians, and the entire world. To countries in conflict, war is more than the numerical cost in dollars. War brings the most awful in mankind, additionally demonstrates our boldness, our faith, and our ability to sacrifice. It also takes so much time to recover from its effect. Arts, including poetry succeed to show the horrific meaning of the war....   [tags: Poetry, Charge of the Light Brigade, Crimean War]

Descriptions of Battle in ‘The Charge of the Light Brigade’ and ‘The Destruction of Sennacherib’

- In this essay I am going to compare and contrast the differences between ‘The Charge of the Light Brigade’ and ‘The Destruction of Sennacherib’. ‘The Charge of the Light Brigade’ is written by Poet Lauriat Lord Tennyson and ‘The Destruction of Sennacherib’ is written by Lord Byron. They both contain different poetic techniques and write about a battle in completely different ways. The historical context behind ‘The Charge of the Light Brigade’ is that it is a battle in October 1854, which was a disastrous charge of British cavalry led by Lord Cardigan against Russian forces during the Battle of Balaclava in the Crimean War, Tennyson wrote the poem pointing out the courageous and the tragic....   [tags: battle, Charge of the Light Brigade, Destruction ]

Essay on War in the poem The Charge of the Light Brigade

- War in the poem The Charge of the Light Brigade “The Charge of the Light Brigade” is about battle and the death of soldiers, and the experience of war. Tennyson´s poem celebrates the glory of war, despite the fact that, because of an error of judgment someone had blundered, six hundred soldiers were sent to their death. The first verse starts in the middle of the action as Cardigan the commander, gives the order to charge. “Forward the light brigade charge for the gun.” This gives a sense of the excitement of the galloping horses in the cavalry charge, and sweeps the reader along, Tennysons then uses noble sounding euphemisms like “into the valley of death” to describe the fate that awaits...   [tags: The Charge of the Light Brigade Poetry Essays]

Polarization Essay examples

- Polarization Polarization is a tendency to reason only in terms of extremes or opposites. The most common type of polarization is group polarization. Group polarization in general refers to the notion that judgments made by a group tend to be more extreme than judgments made by individual members. The concept of group polarization developed from a notion of the “risky shift.” It was originally thought that after group discussion, individuals would make riskier decisions than before. However, researchers then realized tendency could also be to the other extreme; that decisions could shift to a more cautious judgment....   [tags: essays research papers]

Essay on Charge Nurse

- To date there has been limited research on charge nurse competencies, job satisfaction, and development. Additionally, there are no validated instruments to measure these constructs as they relate to charge nurses. Charge nurses are usually not in a defined permanent charge nurse role as delineated by a job description, but rather rotate through if assigned for their shift (Krugman & Smith, 2003). Additionally, many charge nurses enter their role through default (because they are the most experienced or tenured on their shift) and without formal training (Sherman, 2005)....   [tags: Health Care, Nurses]

Essay on Polarization

- Polarization Introduction: PART ONE: POLARIZATION Method 1: Two polarized disks were put into a grooved holder with their polarization axes lined up, and a bright red light emitting diode (LED) was placed on one side, and a light sensor was placed on the other side. Light intensity was measured as a function of the plastic rotating polarizer angle from 0 to 180 degrees. Science Workshop was used to measure the intensity for every 5-degree rotation (Fig 1). Method 2: The mineral calcite exhibits birefringence (double refraction), and therefore has two different values for its index of refraction....   [tags: Papers]
