(Originais Teachy 2023) - Question Medium of Physics

During an experiment in the laboratory, the 2nd year high school students tested various materials to determine if they were conductors or insulators. They found that a specific material conducted electricity when subjected to an electrical voltage, but did not conduct heat when placed between two different temperature sources. Which of the following alternatives best describes this material?
Electrical conductor and thermal insulator
Electrical conductor and thermal conductor
Electrical insulator and thermal conductor
Electrical insulator and thermal insulator
None of the above alternatives

Question 1:


During a Physics laboratory class, the teacher presents two different materials to the students: a piece of copper and a piece of rubber. He asks the students to analyze the properties of the materials and evaluate their suitability as electrical conductors and insulators. Considering the activity proposed by the teacher: a) Identify which material is a good conductor and which is a good electrical insulator, justifying your answer based on the properties of the materials. b) Describe a daily application where the proper use of a conductor and an electrical insulator is important for safety and/or sustainability. c) Propose a safe and sustainable solution involving the mentioned materials in the local and daily context, taking into account their properties as electrical conductors and insulators.

Question 4:


A mechanic is using a wrench to tighten the screws on a car wheel. The wrench is 0.5 meters long and the mechanic applies a force of 100N at the end of the wrench, perpendicular to its length. (a) Calculate the torque applied to the nut by the action of the wrench. (b) If the mechanic needs to apply a greater torque to loosen the nut, he can increase the force or increase the length of the wrench. Which of the two increases will be more effective? (c) To loosen the nut, the mechanic decided to use a wrench with a length of 0.75 meters and apply a force of 90N. Determine the torque applied with the new wrench.
