Why significant figures represent the precision of a measurement and not its accuracy.?
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
Is there at least one integer whose absolute value is zero?
Sure. Exactly one integer to be precise. |0| = 0.
Who was the first to measure the precise speed of light?
The Danish astronomer Olaus Roemer was the first to measure the speed of light. (within 25 % of the actual value)
What tool used for measuring precise volumes of liquids?
A graduated cylinder is used measuring precise volume of liquids.A graduated cylinder is used measuring precise volume of liquids.
Why reading on voltmeter has high precision rather than accurate?
Accuracy and precision mean two different things scientifically. Precision is measured in significant figures -- how many digits (not counting leading zeroes) are used to express the measurement? For example a temperature of 98.6 degF is more precise than 99, but less precise than 98.63. For practical purposes nearest tenth of a degree is sufficient precision. Accuracy is how close the measured value is to the real value. If your voltmeter reads 4.993 volts that's very precise -- but if you know the real voltage is around 6 volts, then the meter is not at all accurate so all those digits are meaningless.
Declare a numerical variable precise and initialize it to the value 1.09388641?
double precise = 1.09388641;
Is less precise instrument always more accurate?
No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).
What is the precise measurement 5.7 mm or 3.6 m?
The precise measurement is 5.7 mm for the first value and 3.6 m for the second value.
Can a value be both precise and approximate?
Yes. Precision and accuracy are different specifications. A value may be precise but inaccurate, or, to put it in other words, it may be precisely wrong.
How do you spell accurite?
The correct spelling is accurate (precise in aim or value).
What is value of 1892 British silver penny?
Between $5 and $240.For a more precise value, please add the condition of the coin.
Is it possible to be accurate and not precise?
The term "precise" refers to the range of measurement to which a value is calculated. The term "accurate" implies that the measurement value is essentially correct, to within some range of error.However, the terms are often used synonymously, since "precise" has the desired quality of being exact, which in some cases is a separate concept from accuracy.
What is a Systematic?
Systematic error is the difference between the actual value of what is being measured and the value you found. The results of systematic error are precise but not accurate.

What is the value of a Elizabeth six pence dated 1965?
Between 10 cents and $1.80. For a more precise value, please add the condition of the coin.
According to the rules of significant figures 7.8987 plus 5.23 equals 13.13 This is because the least precise value in the problem is 5.23 which is precise only to the hundredths digit so the answe?
true
What is the difference between precise and accurate?
Accuracy is how close to the truth and precision is how narrow the the range of uncertainty or error. For example in guessing weight, of 150 # person, an accurate guess could be 140 # +- 15 #. An inaccurate guess would be 145# +- 2#. The first guess is accurate but not precise, the second is inaccurate but more precise.
