From the examples below choose only two and indicate the type of collision each represents. Justify each choice using concepts from this unit. Two billiard balls are moving toward each other along an essentially frictionless surface and collide head-on.
While distracted by the sun, a driver heading eastbound doesn’t see a stop sign and proceeds to drive through an intersection. Meanwhile, another car travelling southbound enters the intersection and collides with the eastbound vehicle. Both cars remain together after the initial contact occurs.
Standing at the baseline of a tennis court, a tennis player tosses a tennis ball over her head swings at the ball. The racquet hits the tossed ball and travels to the other side of the tennis court.
A rubber ball is thrown at an aluminum can. Hitting the can, the ball causes a dent in the can.

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 don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
