Coding problems: HW5_2 A thin square metal plate has uniform temperature of E1 47, = E, + E2 + T2 + T, degrees on two opposite edges, a temperature of E2 on one edge, 4T2 = E, + T1 + T3 + T5 and E3 on the final edge. Equations can be written for the 4T3 = E1 + E3 + T 2+ T4 temperatures, Ti, at 6 uniformly spaced interior nodes. Solve for the 4T, = E1 + E3 + T3 + T5 node temperatures when E1=80, E2=120 and E3=60. 4T5 = E, + T2 + T4 + T6 Present the results in a complete sentence using fprintf 4T, = E, + E2 + T, + T5

An aluminum wire having a cross-sectional area equal to 4.60 x 10-6 m? carries a current of 7.50 A. The density of aluminum is 2.70 g/cm³. Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wire. 1.95E-4 The equation for the drift velocity includes the number of charge carriers per volume, which in this case is equal to the number of atoms per volume. How do you calculate that if you know the density and the atomic weight of aluminum? mm/s

Write a script that will create 10,000 random resistors with a normal distribution, a mean of 100 ohms, and standard deviation of 15 ohms. Perform the following operations with the resistor data using logical vectors where appropriate. Output the total number of resistors created along with their actual mean and standard deviation as they will differ slightly from the values given. Output the percentage of resistor with values > mean and < mean. • Output the percentage of resistors within +/- 1 Standard Deviation of the mean. • Repeat step 3 for +/- 2 Standard Deviations and +/- 3 Standard Deviations. • Output the resistor position numbers and the corresponding resistor values for all resistors outside of +/- 3 standard deviations of the mean. • Name the program file Program_05_2.m • Your output should match the output shown below. Add the standard comments similar to those that appear at the top of each tutorial and clearly label your output following the example shown below.
