The following passage explains how the fundamental forces were discovered. Which sentences state incorrect information? Select all that apply. People have known about gravity as a force between massive objects since before written history, so no one knows who first discovered it. Its mathematical representation was produced by Isaac Newton. Electromagnetism consists of two phenomena: magnetism and electricity. Magnetism has been known about since before written history. Electricity was experienced through “electric shocks” and certain electric fish. However, it was merely a curiosity until about the year 1000 when electrical experiments were first conducted by a number of researchers in and around Baghdad that showed that lightning is a form of electricity. These experiments culminated in Maxwell’s mathematical representation. The atom’s strong and weak nuclear forces were discovered at the same time when we were first able to peer into a nucleus. The strong nuclear, weak nuclear, and electromagnetic forces are all mathematically described by the standard model.

answer; /// i believe that the correct answer is (c)

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).

he . if i may ask what i your question exactly?

explanation:

u can delete ur account.

1. go on google and write

2 open this and click on your profile pic and if your profile is not appearing, then u have to log in.

3. when u click on your profile pic, there appears four options on the top.

4. click on the 1st option and scroll down and go at the bottom.

5. click on edit profile.

6. there appears a option 'prefernces' and at that option at the right side , 'edit' is written.

7. click on the edit option.

8. there is a option " i want to delete my account" and click on that.

hope this u

and ur welcm
