The upward and downward movement of air in the atmosphere creates pressure systems. arrange the steps in the correct order to describe how a high-pressure system forms and leads to pleasant weather. the skies clear, making way for pleasant weather. cool, dense air begins to sink downward. pressure differences cause wind to blow outward. a high-pressure system forms.

Cool, dense air begins to sink downward.

A high-pressure system forms.

Pressure differences cause wind to blow outward.

The skies clear, making way for pleasant weather.

Explanation:

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).

i think the answer is a and b

i wish you luck
