A Physics student is conducting an experiment with a wrench and a screw. The wrench has a 30 cm long arm and a force of 50 N is applied at the end of the arm, perpendicular to the screw. He wants to adjust the screw by applying a specific torque. a) Calculate the torque applied by the student to the screw. b) If the student needs to double the applied torque, what changes can he make to the applied force or the length of the wrench arm? Justify your answer. c) Considering that the screw has resistance to torque, what is the efficiency of the torque applied to the student and what torque is needed to overcome the resistance and initiate the screw's rotational movement?Answer sheet:

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.

An airplane initially flies north at a speed of 200 km/h. Due to a wind blowing from east to west, the airplane ends up deviating to the northeast, following a trajectory that forms a 45-degree angle with the north direction and covering a distance of 300 km from the starting point. Determine, using vector concepts, the speed of the airplane relative to the ground, considering the effect of the wind. Consider that the wind speed is constant and equal to 50 km/h, and that the wind direction is perpendicular to the initial direction of the airplane.
