Yagi-Uda Antenna Let the driven element be kept at the origin and one parasitic element at z=-.125 . Let both dipoles are oriented along x axis. Due to the driven element (1)‚ the current will be induced in (2) and this element is called parasitic element. The current induced in the second element depends on its length‚ radius of the element and spacing. Let the current in driven element and parasitic element be 1 A and 1 2 0.7Ð1400 A‚ respectively. AF = I1e jb d 1 cos q + I 2 e

In our journey through life‚ we all have certain expectations of how we would like our lives to be. All of us strive to reach a certain level of self-actualization and acceptance. It could then be said that all of us live a dream. Some of these individual dreams inevitably become the collective dream of many people. In "Harlem (A Dream Deferred)‚" Langston Hughes makes use of symbolism as well as powerful sensory imagery to show us the emotions that he and his people go through in their quest for

Describe and evaluate the learning theory for attachments. The learning theory suggests that we are born with a blank slate which means everyone starts off exactly the same‚ and then we learn all of our behaviours once we are born. The learning theory is split into two areas‚ Operant and Classical conditioning. Operant conditioning is one part of the learning theory to describe attachments. This states that attachments are formed through positive and negative reinforcements. An example of positive

Null Hypothesis (McMillan‚ 2012‚ p. 49): A null hypothesis states that no significant statistical relationship or difference exists between the groups that are being compared in astudy. This term relates to all of the studies I read for my research study analyses. They all compared the academic achievement of high school athletes and non-athletes in some way or another. While the null hypotheses were not explicitly mentioned in the studies‚ they all would have been something along the lines of

What is the difference between hypothesis and law? A hypothesis is a statement‚ put forth on the basis of reasoning‚ about the things that are being studied. A hypothesis is an educated guess based on past scientific studies and previous experiments. It is not just a random guess. Observation is followed by a hypothesis. For example ‘Plants need sunlight to grow’ can be a hypothesis. It is formulated by taking into account all the observations that are know about the phenomenon under investigation

{text:bookmark-start} Hypothesis Analysis {text:bookmark-end} Scientific Method is a process that is the basis for scientific inquiry. The scientific method follows a series of steps: identify a problem you would like to solve‚ formulate a hypothesis‚ test the hypothesis‚ collect and analyze the date‚ and make conclusions {text:bookmark-start} (“LabWrite Resources“‚ n.d.) {text:bookmark-end} We will cover and give examples of how the scientific method works throughout this paper.
