A current of 0.3 A passes through a lamp for 2 minutes using a 6 V power supply. The energy dissipated by this lamp during the two-minute interval 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.

An isolated, charged point particle produces an electric field with magnitude E at a point 2 m away from the charge. A point at which the field magnitude is E/4 is:

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

Tomando en cuenta la probabilidad anterior, para muestras aleatorias de n=75 llamadas, cuál es el error de la media del tiempo de atención? (El desarrollo y sus conclusiones debe realizarlo en el colab que adjuntará en la pregunta 16. Utilice las funciones adecuadas vista en clases)
