There are many, but the most important are usually - the person doing the measuring, the mesuring device, the environment where the measurement is being made and variability in the item being measured.

What is the uncertainty in the measurement for the speed of light?
The length of a meter.
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.
What is the uncertainty in measurement when using a stopwatch to measure time?
o.1
Why is 5 dogs an unlimited significant digit?
It is not a measurement, therefore, it is infinitely precise. There is no uncertainty in the number.
What does the Heisenberg Uncertainty principle mean?
In any measurement, the product of the uncertainty in position of an object and the uncertainty in its momentum, can never be less than Planck's Constant (actually h divided by 4 pi, but this gives an order of magnitude of this law). It is important to note that this uncertainty is NOT because we lack good enough instrumentation or we are not clever enough to reduce the uncertainty, it is an inherent uncertainty in the ACTUAL position and momentum of the object.
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%
How do you calculate uncertainty?
There are several ways to calculate uncertainty. You can round a decimal place to the same place as an uncertainty, put the uncertainty in proper form, or calculate uncertainty from a measurement.
What is a doubt or uncertainty in measurement?
Basically your uncertainty is the innaccuracy or your measurement. For instance if you had a yard ruler that was marked only in inches and the length of the object you were measuring lied somewhere between 12 and 13 inches; you could state that the objects length is 12 1/2 inches ± 1/2 inch. The ± 1/2 part is your uncertainty, it means the measurement could be either 1/2 inch longer or shorter than your stated measurement.
What is the uncertainty in the measurement for the speed of light?
The length of a meter.
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.
Does a measurement of 23.56mL has more uncertainty than a measurement of 23.5mL?
No, its more certain than 23.5 mL
What is the uncertainty in measurement when using a stopwatch to measure time?
o.1
Is there is any perfect measurement?
No, no measurement we can ever do will be entirely free of uncertainties. In some measurements the uncertainties might be negligible however. In any best precise & accurate measurement there will be minimum uncertainty equal to h/2pie, that's in accordance to Heisenberg's uncertainty principle.
What is meant by a mas measurement expressed in this form4.6g 0.2 g?
I suppose that you think to 4,6±0,2; 0,2 is the uncertainty of the measurement.
Identify three types of uncertainty when you run a business?
There are three types of uncertainty when owning or managing a small business. The three types of uncertainty are state uncertainty, effect uncertainty and response uncertainty.
Do some measurement have no uncertainty?
Yes. A coin lands Heads or Tails. Or a normal die lands with one of the numbers 1 to 6 on top. there is no uncertainty about the outcomes.
Why is 5 dogs an unlimited significant digit?
It is not a measurement, therefore, it is infinitely precise. There is no uncertainty in the number.
