A certain wire has resistance R. Another wire, of the same material, has half the length and half the diameter of the first wire. The resistance of the second wire is:

The figure shows three situations in which the same charged particle is surrounded by a concentric Gaussian sphere, with the radii as drawn. Rank them according to the magnitude of the electric field at all points on the Gaussian sphere, greatest first.

This section of text provides all parts of the problem in one place before breaking the problem down into different problems for submissions. Each problem is presented in this way to allow students to see all required calculations for a cycle in one place.   Problem 3 – 30 pts A vapor compression cycle has a mass flow rate of 0.05 kg/s. R-22 enters the compressor (η = 80%) at 2.5 bar, 15 °C and then is compressed to 9.0 bar. The R-22 exits the condenser as a saturated liquid. To approximate entropy: first two decimal places should match (a) 18 pts – Determine the cooling capacity of the cycle (tons)     (b) 5 pts – Determine the coefficient of performance     (c) 7 pts – Draw the TS diagram for the cycle, denoting where States 1, 2, 3, and 4 are located. Show ideal and real states where appropriate. Label pressure lines.

Problem 2 – 35 pts      Part (a) A Diesel cycle begins with 12 L of air at 300 K, 1 bar. The cycle operates with a compression ratio of 23.25 and a maximum temperature of 2250 K. To approximate vr: first decimal place should match    (a) 29 pts – On an air-standard basis, determine the thermal efficiency of the cycle (%)   PDFs: ME3523_FormulaSheet_Exam3.pdf ME3523_ThermoTables_MoranShapiro_9thEd.pdf

El Gerente de CX, espera un buen rendimiento y por eso quiere premiar a quienes reciban una evaluación de al menos nota 6. Tomando una muestra aleatorias 50 llamadas sacado de la base de datos, cuál es la probabilidad de que la satisfacción de los clientes cumpla la satisfacción esperada? Considere que la variable abalizada distribuya normal  (El desarrollo y sus conclusiones debe realizarlo en el colab que adjuntará en la pregunta 16. Utilice las funciones adecuadas vista en clases)

Problem 2 – 35 pts      Part (b) A Diesel cycle begins with 12 L of air at 300 K, 1 bar. The cycle operates with a compression ratio of 23.25 and a maximum temperature of 2250 K. To approximate vr: first decimal place should match    (b) 6 pts – Complete the P-V diagram for the cycle by denoting where states 1, 2, 3, and 4 are: Draw this diagram and include it in your work submission To show you understand the directions, enter this work in the blank: DIESEL

Tomando un nivel de confianza del 97%, entre que valores se puede atender a un cliente que llama al contact center del segmento hogar? (El desarrollo y sus conclusiones debe realizarlo en el colab que adjuntará en la pregunta 16. Utilice las funciones adecuadas vista en clases)

Apoyándose de una tabla adecuada, estime la probabilidad de que una llamada sea resuelta si el cliente que se atendió era del segmento hogar. (El desarrollo y sus conclusiones debe realizarlo en el colab que adjuntará en la pregunta 16)

The higher the pulse repetition frequency of a Doppler exam, the more likely aliasing is to occur.

Color flow doppler imaging incorporates pulsed Doppler principles and provides range resolution.
