2)Tf = (0.00089 +/- 0.00008) * (13 +/- 2) + (19.627 +/- 0.004)
Tf = (0.012 +/- 0.002) + (19.627 +/- 0.004)
Tf = 19.639 +/- what value?
To find the uncertainty value of Tf, we need to determine the total uncertainty of the expression (0.012 +/- 0.002) + (19.627 +/- 0.004).
To calculate the total uncertainty, we add the individual uncertainties:
Total uncertainty = uncertainty_1 + uncertainty_2
For the given expression, the total uncertainty can be calculated as follows:
Total uncertainty = 0.002 + 0.004
Total uncertainty = 0.006
Therefore, the total uncertainty for Tf is 0.006.
