1. Describe, with an example, the operation of the transistor “ push- pull” amplifier.
An electronic circuit is a source of current and one as sink, to amplify a signal that used in a two transistor or vacuum tubes. There is one device “pushes” current out into the load. The other device is “pulls” current from it necessary. This will be combined to each other and it will work together. For an example, the complementary- symmetry push- pull output, the stage will be widely used to driven loudspeaker, which we can’t see because it is illustration. Whenever the NPN can push or can be called as source current from the positive output that the power can supply into the load, or a PNP transistor can pull and also can be called as sink the current into the negative output to supply power. The circuit is known as amplifier that be

The stator is usually low, and receive input signal from a synchro transmitter. Voltage appearing across the terminals of these differences rotor (R1, R2, and R3) are determined by the magnetic field produced by the stator currents, the physical position of the rotor, and the step-up turns ratio between the stator and rotor. Magnetic field created by the stator currents, consider the angle corresponding to a magnetic field in the transmitter supplying the signal. The player controls the amount of magnetic coupling occurs between the magnetic field of the stator and the rotor, and therefore, the amount of induced voltage in the rotor windings. If the player changes in response to mechanical input, the voltage induced in the coil which is also changing. Therefore, the output voltage of the TDX different result from either changes in the stator voltage input or changes in the mechanical input to the rotor. This electrical output of the TDX may be either SUM or DIFFERENCE both input depends on how the three units (TX, a TDX, and TR) is
Conductor: stranded wires from copper or aluminum with a suitable cross sectional area relating to the ampere of the load 2. Inner semiconductor: uniform and distribute the electric field to prevent interference between

At first, the magnetic field sensor was plugged into analog A. Next; a magnetic field sensor was open in the Database Studio software by following several instructions. Once the magnetic fields sensor was free, we clicked on the “digits” that was on the lower left side of the screen. Then, the window appeared where it was ready to record the magnetic field. After the computer part was completely set up, we measured the diameter of the Helmholtz coil several times to get the more accurate measurement and recorded the measurement in the data. Later, we set up our device in a way that current flows in the same direction for all the coil.
Unit D Summary: Light and Geometric Optics 10.1 : Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy).

A function has three sections the input, relationship and output. e.g. input is a number = 4 relationship is a condition = *2 Output is the value= 8 /*these three steps shows a function.*/ There are numerous types of functions and every type has its own particular diagram.
The article, “CJ2K:The Hard Way” written by Alan Shipnuck. The article is inherently about Chris Johnson (a famous football player for the Arizona Cardinals). Starting, about his old problems with his team and children and how he got through it in a full-hearty way. Later on, it talks about how he practices countlessly and on how he always tries to score so high leading to his goal to have to make a rush for 2,000 yards (which is a gigantic goal in football). Which you can see that he is determined to do great (in football), and that he will not do arrogant things when in trouble.
Empirical background After Robert Agnew introduced the General Strain theory in 1992, he received several support from researchers regarding of his theory including himself. Broidy and Agnew (1997) conducted a study on why the crime rate is higher among males and why also females engage in crime. Broidy and Agnew (1997) hypothesized that males are always subject to different types of strain that would result to serious crime and also males are always subject to financial strain and interpersonal conflict that would lead into violence. Broidy and Agnew (1997) found that females commit crime when they are restricted of conversation, physical and emotional expression, social life and others. Years later, Agnew (2001) examined the characteristics of strainful events and conditions that influence their relationship to crime and he found out that strains are most likely to result in crime when they are seen as “unjust, high in magnitude, associated with low social control, and create some pressure or incentive to engage in criminal coping.”
Theme Essay Getting cared for may be the best thing that you could wish off. But caring for each other can also bring happiness. Through time and difficulties you face, it can create or enforce your relationships. In the story “Gate A-4”, Naomi Shihab Nye was wandering through the airport terminal after she got informed that her flight had been delayed, until she hears an announcement saying, "anyone in the vicinity of gate A-4 that understands Arabic, please go to the gate. " The theme starts to develop as Naomi decides to help the Palestinian lady in her own time, throughout the time they spend together, they start to create a relationship.
Tom Buchanan is Fitzgerald’s masterpiece of creating a character who portrays the life, and characteristics as an alpha male. Through the vision of character’s surrounding Tom we began to see how his loftier masculinity characterizes him in the story. I begin with a quote from Tom’s wife Daisy that embodies the intimidating masculine characteristics of Tom, “I know you didn’t mean to, but you did do it. That’s what I get for marrying a brute of a man, a great, big, hulking physical specimen of a-----” (Fitzgerald 12). In this quote from Daisy we view a list of characteristics that are associated with Tom’s masculinity.
The novel The Great Gatsby by F. Scott Fitzgerald is about how the interactions between money and love have major effects on the relationships between Tom, Daisy, and Gatsby. The relationship between Tom and Daisy is built more on money rather than love, however, there is little bits of love. Daisy marries Tom because of his wealth, but throughout their relationship she does, fall in love with Tom at least once. Also, Tom uses his money to basically buy Daisy’s love showing that he wants to have love in his life. The relationship between Gatsby and Daisy is also built on wealth, but it also involves love, alike the relationship of Tom and Daisy.
After reading “Gate A-4” by Naomi Shihab Nye I believe that the meaning of this passage is shown in the line “ This can still happen anywhere. Not everything is lost.” It shows that the author wants a helping community where food and cultural/tradition is shared. When this elderly women starts to cry in the middle of the airport because she had an important medical treatment, she thought that their flight was canceled, but she understood wrong their airplane was delayed. This women drops to the floor crying, the author explains that she stepped in to help and communicates to her in Aribic, her language so she would understand.
Concertino for flute and piano, Op.107 Cécile Chaminade (1857-1944) Cécile Chaminade (1857-1944) was a French composer and pianist. Her mother, a pianist and singer, provided young Cecile with her earliest musical instruction, who at a later age began to experiment in composition. Her father’s disagreement prevented her from attending the Paris Conservatoire, so instead she studied privately with members of its faculty, which included Benjamin Godard. She started composing music at the age of 8 and performed abroad at the age of 16. Chaminade became a successful composer and concert pianist in the early 1900s, with a tremendous popularity in the United States and was one of the first French female professional composers.
Porters Five Forces Analysis: Samsung Electronics Introduction Samsung Electronics focuses in three specific areas; Consumer Electronics, IT & Mobile Communications and Device Solution. Porter’s Five Forces model has been used to analyse Samsung Electronics competitive position within the global market they operate in. By using this model, an evaluation of their current position will highlight which of the five forces are “affecting the intensity of competition in an industry and its profitability level” (Jurevicius, 2013). Nevertheless, when conducting analysis on an international company such as this, studying of market trends is already carried out thoroughly to ensure that they are fully aware of that market, in order to achieve success and maintain within it. With this in mind, it would be considered that Samsung Electronics would have a relatively good competitive advantage against other rival companies.
