How can I find the uncertainty when a constant is divided by a value with an uncertainty?

Add up the relative uncertainties of both constant and of the divider


Why is Heisenberg's uncertainty principle not more apparent in our daily life?

Heisenberg's uncertainty principle relates the fundamental uncertainty in the values of certain pairs of properties of a particle (e.g. momentum and position, energy and time) to a fundamental constant of nature known as Planck's Constant. Since Planck's constant is extremely small (~6.62


What is Precise Value?

a precise value is that value which has less absolute uncertainty


Suggestions for percent error R gas constant?

The molar gas constant (R), expreseed in J/mol.K, has a value (after IUPAP and IUPAC tables) of 8,314 472 ± 0,000 015. The relative standard uncertainty is 1,70.


Formula to calculate precision?

It will depend what operation you use to calculate your value. First you check the uncertainty of your instruments. Then If you add or subtract two values, you add the uncertainty (even when you subtract) If you multiply or divide, you do the following formula. dZ=(dx/x+dy/y)*z dz: uncertainty of your final value z is your value dx is the uncertainty of your first value x is the value of you first value similarly for y which is you second value


What is a non zero constant?

That means the constant has a value that is different to zero.That means the constant has a value that is different to zero.That means the constant has a value that is different to zero.That means the constant has a value that is different to zero.


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%


What is a value that does not change?

A value that does not change is a constant.


Is the value of soil always constant?

No. The value of soil is not constant.


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.


How do you calculate measurement uncertainty for acceleration given uncertainty in time?

If the distance is known to perfection, an acceleration is constant, then the absolute error in the calculation of acceleration is 2/t3, where t is the measured time.


Does your value of R agree with the accepted value within your uncertainty limits?

It depends on the results of your experiment.
