am doing past years, but stuck on this question, answers with explanation is appreciated thx

what letter is the answer? thankyou no need for solution

11. Draw a circuit for each of these acts that adheres to the particular given requirements.  (Label all components, including voltage source) Materials: 1 Power source (Battery pack – 4.5 V) Bag of wires 1 Single-throw switch 1 Double-throw switch 5 light bulbs 2 green, 1 red, 1 yellow mini-ziploc baggies *When the single switch is thrown (closed), Lead Singer, Backup Singer 1, and Backup Singer 2’s lights are ALL turned on. *In the middle of the performance, Backup Singer 1’s light unfortunately goes out, and only the Lead Singer remains lit. *If power is cut to the Lead Singer’s light, make sure that both Backup Singers remain lit.

The disconnecting means for the motor-operated appliances such as the fuel-fired furnace discussed in this chapter is required to comply with NEC ______. a. 725.136(A)b. 422.31(C)c. 422.60d. 725.179(G)

I'm unsure whether my calculations for these questions are correct; may I get your answers and solutions if we have the same idea? Thank you soo much!

You have been asked by your manager to deal with the following contract that has just been taken on by your company. A car manufacturer requires lighting for its production line. The factory has a 20,000m2 floor space and is a square. The production is split into 5 main  areas which are as follows; CNC plant/ manufacture and welding bays Robotic assembly/ engine testing Stores Spraying/ bodywork Offices You may assume the areas are split evenly in dimension within the   factory. building. You can further assume the factory has a height of 20m, and that the lights will be suspended by 5m from a level ceiling. CIBSE publish required lighting intensities for each purpose. In addition, you can also use a 1m working height in any calculation. Investigate what types of lighting should be used for the different areas based on the strength of light required to illuminate the plan effectively. It is up to you to choose the types of lights used in the different areas, and the quantity of each…
