Which of the following changes the mass of an object? a.)nothing, mass stays constant b.)changing the distance from the center of gravity c.)changing the gravitational pull of the planet d.)changing the distance from the surface of the planet

A) Nothing, mass stays constant

Explanation:

As we know that mass is the measure of the quantity of the matter and it remains the same until we break or remove the part of the mass from its system.

So here we can say that

as the gravity change the value of the gravitational force will change as we know that

so we can say that

all the effects of height or distance from the center will change the gravity due to planet so it will not affect the mass of the system

so here correct answer would be

A) Nothing, mass stays constant

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).
