Students in a lab are doing experiments involving the motion of objects. They pull an object across a table and use a detector to measure the acceleration of the object for the entire time they pull it. The graph shows the data from
the detector, with four segments labeled.
Acceleration
3
Time
For which segments of the motion is there a net force on the object? Explain how the graph indicates this. Enter
your answer in the box provided.

Explanation:

Did you ever end up getting an answer? Or like did you find out which segment it was?

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).
