Topic 12 ATOMIC STRUCTURE: Electronic configuration 12. 1. Ionization energy If an electron obtains enough energy it jumps beyond the highest energy level and becomes a free electron: the atom itself becomes a positive ion. This electron transition is represented as follows: n = 1 to n = (. Notation n = ( refers to the “world” outside the atom – beyond the control of the nucleus; any electron outside an atom has no potential energy (energy = 0). With hydrogen the ionization energy can be

1.0 Introduction There are four parts of cybercrime attack that got to be discussed in this assignment. These included Distributed Denial of Services‚ identity theft‚ social engineering and man-in-the middle attack. A topic that will be covered is type of vulnerability‚ type of attack‚ the impact of those attack and protection mechanism used to prevent attacks to happen. 2.0 Distributed Denial of Services (DDOS) 2.1 Type of Vulnerability The first vulnerability that will cause hackers to infect

relative there through mobile phones. It has been observed that students bringing electronic gadgets to school are distracted from their studies. Intrapersonal reaction and communication are missing because studies are immersed in texting and gaming. There is a need to conduct a study of this condition because it has been proven by the result of Annual National Test of the DepEd that students with the most electronic gadgets in the cities and towns have lower result in these tests compared to rural

Kristi Malone The Electronic Era was responsible for the advancement of technology. In my opinion‚ the biggest forms of technology that came were cell phones and personal computers. The invention of cell phones made it possible to communicate with others while not around a landline. It was also now possible to call for help if an emergency arose. The invention of personal computers came with the invention of the internet and made it possible to research a topic of interest without spending hours

(t). d. Determine the modulation index. e. Determine the modulation efficiency. You are asked to design a DSB-SC modulator to generate a modulated signal km (t) cos ωc t where m(t) is a signal bandlimited to B Hz. Figure shows a DSB-SC modulator available in the stockroom. The carrier generator available generates cos3 ωc t instead of cos ωc t. Explain whether you would be able to generate the design using only this equipment. You may use any kind of filter you like. 4. 5. The system shown

inside in a shadowy cold room with their eyes glued to a television with scenes of gory video games of people shooting each other’s heads off. Family dinner talks turn into family members scattered throughout the house entranced in their own little electronic world. The over-use of technology is creating an impatient society and it is also diminishing once-valued personal interaction with others. More often now these days‚ people would rather let a machine take a message instead of answering a call;
