Final answer:
To calculate the absolute uncertainty in the function f = 4.2x/y², you need to use the formula for propagating uncertainties in a quotient, but the provided reference data cannot be used for this calculation.
Step-by-step explanation:
The student is asking to calculate the absolute uncertainty in the function f = 4.2x/y², given the values of x and y with their respective uncertainties. To find the absolute uncertainty in f, use the formula for propagating uncertainties in a quotient, ∆f = f ∙ (∆x/x + 2(∆y/y)). Substituting x = 2.40 ± 0.01 and y = 1.10 ± 0.04 into this formula will give us the absolute uncertainty of the function f. However, the data provided in the reference does not directly relate to the question of uncertainty in f, so these cannot be used for calculation. Instead, we will apply the appropriate formulas using the accuracy and precision of the provided x and y values.
