Magnitude --> absolute value so either C or D....
I'll go with D. |

Are the bracket dodads representative of magnitude?
I honestly do not remember learning about magnitude at any point in school. |

Magnitude doesn't have direction, so A. Not confident that's what the teacher thinks is right.

Its C, technically C and D say the same thing but because the negative sign is meaningless in a magnitude I personally wouldn't write it like that. Depending on the teachers intent, after you apply the |-10| operator it does equal 10 so maybe that's the answer that's being asked for? That's pretty cool she's learning about stuff like that so early!

the only correct answer would be: the pile of removed dirt next to the hole, shows the magnitude of the hole

Without a datum, the purest answer is C. A is acceptable. B and D are not acceptable answers.

|-10| is likely what the teacher lady is asking.
But A, C, and D are all valid end answers in my opinion. |

This is why I take either so long as the kid uses a sentence with it. My curriculum wants both. I'm very lenient in regard to what I take for this lesson.

it is the AV of the well depth. math and measurements are abstract so there are all sorts of ways to use it in very specific applications, like the limited circumstances when AV would be practically applied

Magnitude seems like a vector, value and direction It seems like A, C, D are the same value expressed in different ways. |

B and C. B is ten below zero and C is the absolute value of -10 ( distance of ten units from zero on the number line ).

If we were in the real world, like a chemical plant, and measuring something like absolute pressure, it would be 4.7psia (
).I’d mark up the question with “answers do not denote units so none are correct.” |

Magnitude is a representation of distance, which is found using absolute values. As a result, the answer should be |-10|.
i.e. the hole is 10 feet deep, hence the -10. Its magnitude is the absolute value of its depth, |-10|. |

The MAGNITUDE IS REPRESENTED BY THE ABSOLUTE VALUE.
|10|=|-10| = 10 So in this case any of these above answers would be considered to be correct. The Magnitude wouldn't have a negative sign on it since Magnitude does not indicate direction. A physical example would be speed vs velocity....velocity has BOTH speed and direction...speed would be the MAGNITUDE However if one wants to get more technical another way to look at it would be in terms of exponents and base....if we are talking about Base 10 then the order of magnitude (exponent) would be 1 (10^1) (10^1 = 10) However both |10| and |-10| would equal 10...so we're back to square one (no pun intended) |

Quote HistoryQuoted: It's d. It's the absolute value of -10. Jeff has 8 apples and and Mary has 4. What's the ratio of Mary's apples to Jeff's? 2/4 2 1/2 4/8 I agree that d is probably what the teacher is looking for though, and the problem is likely more difficult than anything an elementary education major had to learn in college. They're not even required to take algebra in some programs. |

Quote HistoryQuoted: Magnitude is a directional value that represents distance. As a result, the answer should be |-10|. No. By definition magnitude does not have direction. Anything with a negative sign is not written correctly, and the absolute value symbol is completely redundant. |

If anything this demonstrates the dumbness of government school vs. real world “we need to make a profit and not kill/injure people” math.
“You got the answer wrong because you did the little bar symbol wrong” Vs “They forgot to tell you it’s 10bar, not 10inwc, so you’re dead now, my bad.” |

How are you an engineer that doesn't know the symbol for absolute value? Are you really an engineer? Like as in licensed engineer??? Yes. I’ve reviewed thousands of data sheets for every type of valve and instrument imaginable and the magic symbol for absolute value has been used on exactly zero of them. An absolute unit, like pressure, would be indicated as “psia” as opposed to something like psig for gauge pressure. ETA: okay, I read an write up on it and it jogged my memory from back in school. Not exactly the same thing as absolute pressure. |X| is literally never used in petrochemical or oil & gas engineering. I stand by my statement that all answers are wrong because they are unitless. Also A, C, and D are all the equal. I’d really like to hear the teacher’s explanation for why one is correct. |
