fixing the value of R2 to be 10K‚ as shown in figure. We were asked to calculate the voltage gain of the amplifier for the two different values of Rc. Figure 2 Source: Figure 2 Source: In this task we used the function generator to produce a sine wave of 30mV and 50mV Vp-p at the frequency of 50 KHz. We connected CH1 to fed this generated signal in the oscilloscope at Vin. In the other hand‚ Vout should be connected to fed CH2 of oscilloscope. The voltage gain of the amplifier was to be calculated

Within the United States today there is a contradicting topic on whether or not‚ competitive eating should be stopped. According to “Should We Ban Competitive Eating” by Sarah McCarry and Adee Braun‚ “Competitive Eating: How Safe Is It?” by Richard Sine‚ “Step Away From the Hot Dog: Should Competitive Eating Be Banned?” by Dakshana Bascamurty‚ and “Should Competitive Eating Be Banned” by Kelly Yang‚ see competitive eating as an entertainment that is hurting the world and should be stopped.

possible. In addition‚ some aficionados prefer thermionic valve (or "tube") designs over transistors‚ for a number of reasons: Tubes are more commonly used in class A designs‚ which have an asymmetrical transfer function. This means that distortion of a sine wave creates both odd- and even-numbered harmonics. They claim that this sounds more "musical" than the purely odd harmonics produced by a symmetrical push-pull amplifier. Though good amplifier design can avoid inducing any harmonic patterns in a sound

QP engaged Nasir in participating in a CBT activity geared towards coping with feelings. QP explained to Nasir that the activity will help him to cope with his anger and upsetting emotions ‚ identify when he is feeling upset ‚ how to deal with these emotions in ways that are healthy and productive‚ and learn how to cope with negative emotions. QP asked Nasir to list some of his negative emotions he feels. QP asked Nasir to list some things that is causing him to get upset at home. QP asked Nasir

voltage [pic]is passed through a half-wave rectifier which clips the negative portion of the wave. Expand the resulting periodic function as a Fourier series [pic] 6. For the function defined by the graph OAB‚ find the half-range Fourier sine series. 7. The damped vibrations of a stretched string are governed by the equation [pic] equation (1) where [pic] is the transverse deflection‚ t is the time‚ [pic]is the position coordinate along the string

Initially‚ I wanted my research topic to be about the affects of foster care in adults. I was thinking about this topic because many of my friends‚ who are now adults‚ have been adopted or in foster care at some point in their lives. And many of them are struggling. A few have inadequate living conditions or are living on the streets. Another is struggling to stay in school. And a couple are on drugs. I wanted to know if these hardships were related in any way to that fact that all of them have been

Vasco de Gama was born in 1460 in Sines‚ Portugal. He had many accomplishments in his life. Some of his accomplishments are very well known‚ others only known by very few. When de Gama was young he joined the navy because he knew he wanted to learn how to navigate. On his first voyage he was young and more unexperienced than most others leading voyages. Later in life‚ de Gama was appointed to find a route east because this‚ what they thought‚ safe route was needed to retrieve spices. He was successful

refer to the harmonics of the instrument we are specifically talking about the modes of vibration. The modes of vibration are what we use to identify the characteristics of an occurring vibration. In other words‚ we identify notes based on what their sine waves mode is‚ in comparison to the fundamental frequency. Another common term used to associate with the modes of vibration is partials; however the word is typically used to describe the overtones or complex tones. Understanding partials is vital

Ambiguity is a theme that runs through many narratives and due to itss nature can serve multiple purposes. At this moment‚ ambiguity will be explored in‚ “The Minister’s Black Veil” by Nathanial Hawthorne. The short story is about Parson Hooper‚ a minister for a small town‚ who suddenly dawns a black veil across his face and refuses to remove it for any reason. As a result‚ the townspeople begin to gossip and change the way they act. Through the nature of sin‚ Hooper’s life‚ and the purpose of the
