Please help me

In this one, just choose two scenarios, please read the instruction.

7. You are an advocate of disaster prevention and preparedness. Use a van de Graaff generator to teach small children to be careful but not too afraid of thunder and lightning. Make sure that you explain the rules on safety in using the van de Graaff generator, (charging/ discharging, conductors) B. You work in an architectural firm specializing in restoration of old building boss to invest in replacement of rusty and broken lightning rods in the bull 2/4 ing especially the effect of rust and breaks in the rod. 9. You are a volunteer teacher in a first-aid class. Demonstrate how to help a victim of electrocution and explain the reasons behind the various precautionary measures. 10. You are discussing the hazards, risk and possible solutions of photocopiers and printers with the CEO and the building manager of your company. The CEO asked you why there is bright light during photocopy, why print-outs are usually hot and if these heat sources can be avoided. You want that a separate air-conditioned room be set aside for photocopiers and printers. Use your answer to the CEO's questions as opportunity to explain the basic mechanisms of these devices and to push your proposal. 11. Using the principle of superposition, explain to a skeptic why Coulomb's law is able to explain a lot of different phenomena Involving charge despite describing only two charged object. 12. Using order of magnitude estimate, ratio-and-proportion, explain why we are interested in "unreal" charged configurations like "uniformly charged" objects, "very long" charged rod/wire, and "infinite or very wide" charged plane. 13. Create a cartoon or poster explaining the difference between an insulator and a conductor, particularly in terms of the mobility of the electrons, using as analogy (e.g, prisoners and ordinary persons, children before and after a curfew, people in the city during night time and day time). 14. Make a leaflet illustrating the inability of Coulomb's law in explaining the (planetary) model of the atom.WEEK 4 - LAS 4 Electric Potential, Electric Potential Energy Directions: Calculate for the excess charge on a Van de Graaff generator. 1. A Van de Graaff generator has a 0 125 m diameter metal sphere that produces a voltage of 100 kV near its surface. What excess charge resides on the sphere? a. Find the potential at a distance of 0.06 m from a - 5 nC charge. b. What would be the PE of a -4 uC charge placed at this point?WEEK 3 - CONTEXT-RICH PROBLEM Solving context rich problems provide students the opportunities to practice implementing the physics concepts and techniques in realistic scenarios (25points/question), The following are examples of context-rich problems. Choose 2 scenarios and solve the problem. Send your answer to my Messenger. 1. Your classmates often complain of painful electric shock whenever they open the door to leave the new fully-carpeted auditorium of your school. Write a letter to the principal about the problem explaining the physics behind the phenomenon and suggesting simple changes to the auditorium (at least in the area near the door) to prevent this nuisance. 2. You are a fieldtrip when a thunderstorm struck. Making matters worse, your school bus malfunctioned while it is in the middle of the road traversing a wide plain of rice fields. There is a "nipa" hut and a mango tree near the place you are stuck. Convince your classmates that it is safer to stay inside the bus while waiting for help. 3. Your friend told you about her problem. She bought some replacement electronic parts for her personal computer a week ago and only found out yesterday that these were not working When she tried to return them to the store, the salesman refused and told her it was her mishandling that ruined the electronic parts. She said that she was careful that the devices were no subjected to vibrations. She said all she did was remove and throw away the metallic film-coated shipping bags that used to contain the devices. Explain to her why it is possible that indeed she is at fault. 4. Your grandmother gave you silver-plated kitchen wares. These are old such that some parts of the plating are already worn off. Design an electroplating set up to restore this heirloom pieces. 5. An energy saving advocacy group released an cartoon "infomercial" portraying old electric appliances as greedy monsters eating a lot of electric charges. While you support their advocacy, you want their information to be accurate. Write a friendly letter to the advocacy group pointing out their error and suggesting some changes to their "infomercial." You also design a simple demonstration to support your argument. 6. You are in charge of first aid during your Biology Club camping. Unfortunately, one of your club members got sick and dehydrated Explain to him why it is advisable to drink the sugar and salt solution that you prepared
