Anewspaper carrier on her delivery route travels 200 meters due north and then turns and walks 300 meters due east.
a) draw a vector diagram following the directions shown.
1) using a ruler and protractor and starting at point p, construct the sequence of two displacement vectors for the newspaper carrier's route. use a scale of 1.0 centimeter = 50 meters. label the vectors.
2) construct and label the vector that represents the carrier's resultant displacement from point p.
b) what is the magnitude of the carrier's resultant displacement?
c) what is the angle (in degrees) between north and the carrier's resultant displacement?

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).

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

+15-35=-20

going in opposite directions
