If I have to ask the question piece by piece, write down how I should ask it. Subject : "Lineer Algebra"(ElectricalEngineering) Books about the question: "Chi Tsong Chen, Linear System Theory and Design" “John S. Bay, Fundamentals of Linear State Space Systems" NOTE:ACalculatorOrComputerCanBeUsedForNumericalCalculations(MatrixMultiplication,Polynom- ialRoots,Etc.),ButTheQuestionsCannotBeSolvedByTheComputer.SomeQuestionsMayNotHaveSolut- ions,ExplainThemWithTheirReasons. Are the following systems linear? Is it memoryless? Is it causal? Explain your answer. Can impulse response and transfer function be found for systems? Find if it can be found, if not, explain why. (Note: The input of the system is “u(t)" and the output is “y(t)". "8(t)" is unit impulse, "1(t)" is unit step function. In some cases, impulse response or transfer function is already given In this case, find what is not given if it can be found.) 11. The system whose state space representation is as follows x = ; x+ B]u y =…

5) We usually think of wires as perfect (R=0) conductors, which is not quite accurate. Real wires have resistance, and an effort is made to keep this resistance small- usually less than an ohm. This behavior rarely becomes an issue with low power lab circuits. However, it is a big issue with power distribution systems as you will see in ENGR202. a. Design a uniform cylindrical wire that has a resistance of 25 m2 and uses $1 worth of copper. What are the length and diameter of your wire? Note: You can find the resistivity of copper in your textbook, and you should assume that copper costs $2.69 per pound. b. This wire is cut in half, and the two strands are used to power a toaster from an outlet supplying 1800W at 120V. The toaster can be modeled as a pure resistive load. Draw a simple circuit diagram, including the voltage source, resistors to represent the power cord wires, and the calculated resistance of the toaster. C. How much of the 1800W is absorbed by the power cord itself, not…
