José recently acquired an electric car and is very excited about his sustainable choice of transportation. During a 200 km trip to visit his relatives, he measured the times it took to complete different sections of the journey. In the first 50 km section, he took 1 hour. In the second 100 km section, he took 1.5 hours. In the last 50 km section, he took 1 hour again. Considering the sections of the journey, calculate: a) The average scalar speed in the first two sections. b) The average scalar speed for the entire trip. c) Based on the results, discuss the importance of using an electric car, taking into account socio-environmental, political, and economic issues.Answer sheet:

Beverages can be chilled more quickly using styrofoam boxes containing ice and a little commercial coarse salt. In this process, the ice melts with consequent formation of liquid and cooling of the beverages. An erroneous interpretation, based on common sense, relates this effect to the great ability of coarse salt to remove heat from the ice. From a scientific point of view, rapid cooling occurs due to more efficient heat transfer between the ice, salt, and beverages.

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.
