What is the difference between accuracy and uncertainty?
accuracy is when you KNOW something and uncertancy is when your not sure
Can you measure quantum uncertainty?
You can measure some aspects of quantum uncertainty.
What is meant by accuracy?
Accuracy is the distance away in percent of a result (or a measure) from the target. This mathematical definition is from the book "A Mathematical Foundation For Politics And Law"
What is the uncertainty of a constant value?
It is the accuracy in the estimate of the constant or the effect of rounding.
What is the percent uncertainty of 1.57m2?
1%
What is the combined accuracy if water flow is measured through 3 meters 90 percent in meter 1 with 3 pcent accuracy 8 pcent in meter 2 with 10 pcent acc and 2 pcent in meter 3 with 15 pcent accuracy?
"3 meters measure water flow90 percent thro meter 1 accuracy of 3 percent8 percent thro meter 2 accuracy 10 percent and2 percent thro meter 3 accuracy 15 percent what is accuracy combined?"if in metre 1 (0.9 X 0.03) = .027and in metre 2 (0.08 X 0.10) = .008and in metre 3 (0.02 X 0.15) = .003then total combined accuracy is 0.027+ 0.008 + 0.003 = 0.038 = 3.8 percent
How does quantum uncertainty differ from the uncertainty involved in a coin flip?
completely: coin is simple probability, quantum uncertainty is based on how increasing accuracy of measurement of one property of a tiny particle reduces the accuracy of measurement of another complementary property of the same particle. No probability there, just measurement limitations.
The closeness of a measurement to its true value is a measure of its .?
accuracy; reliability.
What is the percent uncertainty of a spherical beach ball with radius 0.84 - 0.05m?
The uncertainty in radius is approx 5.95%.
How do you measure uncertainty?
To measure uncertainty, you need to know the precision of the instrument, which refers to the smallest unit that an instrument can measure. A measurement can then be represented with its associated uncertainty, such as X = (5 +/- 1) cm. In this case, the actual value can deviate from the mean (5cm) by 1cm, so the minimum and maximum values ate 4cm and 6cm respectively. The percentage uncertainty is calculated by (absolute uncertainty / mean value) * 100%.
How do you get a probability?
The outcome of some events are cannot be determined in advance. There is an element of uncertainty in the outcome. Probability is a measure of this uncertainty.
What is the percent uncertainty for the measurement given as 4.19m?
When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100. 4.19m take the last decimal unit, is 9 but with value of 1/100 .01 is the uncertainty Now, .01/4.19 x 100 % = 0.24%
