Belie her utter terror Natalie maintained a calm expression Is this correct?
No, Belying her utter terror, Natalie maintained a calm expression is correct.
How much does 20000 liters of liquid sugar weigh?
Sugar is decomposed by heating so melted sugar is not a correct expression. If you think to a solution it is important to know the density to calculate the mass. M= V.d
What is 4 cm in inches?
If I am correct there are 2.54 centimeters in one inch, and 4 times 2.54 equals 10.16 centimeters. Algebraic Steps / Dimensional Analysis Formula 4 in* 2.54 cm 1 in = 10.16 cm
Which shows the correct way to convert 5 ounces to pounds?
5/16 pounds Algebraic Steps / Dimensional Analysis Formula 5 oz*1 lb 16 oz=0.3125 lb
Convert 35 cm to mm?
350 Algebraic Steps / Dimensional Analysis Formula35 cm*10 mm 1 cm=350 mm +++ While that second part may be correct in principle it adds needless complexity. Dimensional Analysis is an algebraic tool for developing and verifying complicated formulae, not for simple unit conversions like that. ' All you need know for the Metric System is that the units follow simple tens rules, and to know the names for each multiple or division. ' For this particular question all you need know is that there are 10mm in 1 cm. You don't need to cite algebra text-books at all! ' Sudden illumination... 'Answers' is infested with what seem to be children's homework questions on converting between simple linear metric units. Are they all being baffled by schools making the most basic "sums" in the world's arithmetically-simplest measurement system, into a topic of advanced algebra demanding experience in dimensional-analysis without even knowing the real meaning and purpose of dimensional-analysis?
Is it correct to calculate the standard deviation using duplicate analysis?
No it is not correct.
Is it true that dimensional analysis can tell whether an equation is physically correct?
yes
When doing dimensional analysis when do you round to the correct number of significant figures?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How do you know if the original expression is equivalent to the simplified expression?
you test it by giving the letters a value say if X equals 5 and Y equals 7 then you calculate both expressions with that value. If both answers are the same, then the simplified expression is correct, or an equivalent.
Is the expression Me either correct?
The correct is *me neither* .
How can you tell if an equation is dimensionally correct?
You do the calculations, not with actual numbers, but with dimensions. For example, [length] + [length] = [length], [length] x [length] = [length]2, square root of [time]4 = [time]2, etc. In the final result, left and right of the equation have to be equal. For more information, search about dimensional analysis (for example, the Wikipedia article on dimensional analysis might help).
How do you spell dimensinel?
The correct spelling is "dimensional."
Whats the right expression repent for or repent of?
The correct expression is Repent of.
Is the expression discuss about correct?
No, the correct expression is either "discuss" or "talk about." "Discuss about" is redundant as both words convey the idea of engaging in conversation or exchanging ideas about a topic.
What are the used of dimensional equation?
A dimensional check in an equation can provide a quick check about the possible correctness of the equation. For example, if you are supposed to calculate a speed, the dimensions of the result MUST be of the form [distance] / [time] (or something that you can simplify to distance/time). If it doesn't, the formula is wrong. If it does, it MIGHT be correct.
What does 1 plus cosx?
That can't be simplified. If you have a value for x, you can calculate the expression. Be sure to put your calculator into the correct mode; the angle can be measured either in radians or degrees. You have to know what measurement is being used, but if the angle is written as "x", radians are commonly used.That can't be simplified. If you have a value for x, you can calculate the expression.
