What is the instantaneous value of AC?
The instantaneous value of an alternating current (AC) is the value of the current at a specific moment in time. It is constantly changing direction and magnitude due to its alternating nature, so the instantaneous value represents its value at that precise instant.
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.
What is the difference between accuracy and precision in scientific measurements?
Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close repeated measurements are to each other. A measurement can be precise but not accurate if it consistently misses the true value by the same amount. Conversely, a measurement can be accurate but not precise if the measurements are spread out but centered around the true value.
Is there at least one integer whose absolute value is zero?
Sure. Exactly one integer to be precise. |0| = 0.
Why is it possible for data to be precise but inaccurate?
Data can be precise but inaccurate because precision refers to the level of detail and consistency in measurements, while accuracy relates to how close those measurements are to the true value. It is possible for precise data points to be consistently incorrect, leading to inaccuracies despite the level of precision.
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.
Can a measurement be precise without being accurate?
Yes, a measurement can be precise without being accurate. Precision refers to how close repeated measurements are to each other, while accuracy refers to how close a measurement is to the true value. It is possible for measurements to be consistently close to each other (precise) but consistently off from the true value (inaccurate).
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 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.
What is the instantaneous value of AC?
The instantaneous value of an alternating current (AC) is the value of the current at a specific moment in time. It is constantly changing direction and magnitude due to its alternating nature, so the instantaneous value represents its value at that precise instant.
Is it possible for an observation to be accurate but not precise?
Yes, it is possible. Accuracy refers to how close an observation is to the true value, while precision refers to how close repeated measurements are to each other. An observation can be accurate if it is close to the true value, even if the measurements are not precise and vary widely.
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?
