This light is lost in the cladding of the receiving optical fiber. Core diameter mismatch loss is typically only a concern with multimode optical fiber. To avoid core diameter mismatch make sure to check the cores of your fiber and make sure they are the same size to the best you can. Intrinsic factors that can affect connection performance in fiber-optics come in many types. A numerical aperture (NA) mismatch occurs when the NA of one optical fiber is different from the NA of the other optical fiber.
Unit 5 Assignment 1: Homework Short Answer 1-7 p.158 1) Explain what is meant by the term “conditionally executed”. Conditionally executed is called a single alternative decision structure because it provides only one alternative path of execution. The action is conditionally executed because it is performed only when a certain condition is true. 2) You need to test a condition and then execute one set of statements if the condition is true. If the condition is false, you need to execute a different set of statements.
One serious blunder could have been not paying attention. Because we had to record the amount of time the Mg strip dissolved, we had to keep a close eye on the reaction. One thing that could have affected this was talking to others around you, or trying to multitask. Generally speaking, systematic and random errors did not have a great effect on my data and results. However, if the blunder were true, my data would have been completely wrong resulting in an incorrect graph and rate law for magnesium.

(i) The data member cost can be set to a new value, by a user of this class (ii) cout<<”The rose has: “ << Rose.getPetals() << “ petals.”; is a valid statement (iii) There is a destructor in the class (Points : 2) i. ii Only i and iii None are true All are true | 8. (TCO 2) Can two methods each define a local variable with the same name? (Points : 2) Yes, as long as the variable is used in the same way. No, this is not possible because the compiler would not know which variable to use. Yes, but only if the methods have the same name.
EXERCISE 23 Questions to be Graded 1. What is the r value for the relationship between Hamstring strength index 60°/s and the Shuttle run test? Is this r value significant? Provide a rationale for your answer. r = -0.149, the r value is not significant since it’s associated p-value = 0.424 > 0.05 which is the level of significance.
It is reasonable to set the value to 0 because if one makes the value 0 we can observe a more precise answer, than if one changes the intercept. When I changed the intercept to 1 the equation decreased and had a +1 to it. It slowly kept decreasing as I increased the number. 6) Compare the equation of the line of best fit for your random sample with the lines
It does not guarantee data integrity and discard packets when there is network congestion. In reality, it still delivers data with high reliability. Frame relay uses DLCI in order to communicate frames from one side of the network to the other, the DLCI should be unique for each path on the network, so that when a frame is sent to a certain location and the DCLI is attached it can be sent to the correct recipient. The DLC looks like the
Grammar checkers miss some problems; something’s give faulty advice for fixing problems, and can flag correct items as wrong. Use these tools as a second line of defense after your own. Pronouns replace and refer to nouns, making writing more
So in the null it is assumed that there is no difference after the development program. 2) Independent samples Let mean grade of posttest = μ1 Let mean grade of pretest = μ2 It is a right tailed test according to me because in the null there is an assumption that after training the grade is either equal or less than before training and in the alternative there is only one possible result and that is the positive impact of training. So in the alternative either the grade is improved or not because it cannot be the same as before. H0: μ1- μ2 ≤ 0 Ha: μ1- μ2 > 0 Level of significance=0.05 Results: Samples | T statistic | P-value | Matched | 1.81 | 0.04 | Independent | 1.68 | 0.05 | Conclusion: In both the cases there is sufficient evidence to reject the null hypothesis because p-value is either equal to and less than the level of significance and this evidence supports the
