The prefix table is used to represent physical quantities more accurately. For example, we can use the prefix 'deci' to represent 0.1 times the unit. If we have 1 decimeter, that means 0.1 meters. Which of the prefixes below means 0.000001 times the unit?

A glass prism is used in a laboratory experiment to separate the colors that make up white light. The prism is in the shape of an equilateral triangle with sides of length 10 cm and a refractive index of 1.5. A monochromatic light beam is incident on the prism and emerges with an angular deviation. For this experiment, consider that the light beam hits the first face of the prism at a 45º angle. (a) Calculate the angle of refraction on the first face of the prism, applying Snell's Law; (b) Determine the angle of incidence of the light beam on the second face of the prism as it passes through it; (c) Using the information obtained in the previous steps, calculate the total angular deviation of the light beam passing through the prism.

A technician from an electronics company is working on a circuit involving three capacitors in series. The capacitors have capacitances of 6μF, 8μF, and 12μF, respectively. Assuming the potential difference applied to the capacitors is 60V, determine the charge stored in each capacitor and the equivalent capacitance of the series configuration.
