Find the uncertainty in a calculated electrical potential difference from the measurements of current and resistance. Electric potential difference depends on current and resistance according to this function V(I,R) = IR. Your measured current and resistance have the following values and uncertainties I = 8.1 Amps, SI = 0.8 Amps and R = 39.7 Ohms and SR = 0.4 Ohms. What is the uncertainty in the SV?|

68. Alveoli are tiny sacs of air in the lungs. Their average diameter is 5.20×10−5 m. Calculate the uncertainty in the velocity of an oxygen molecule (5.30×10−26 kg) trapped within a sac. Enter your answer in scientific notation. (Hint: The maximum uncertainty in the position of the molecule is given by the diameter of the sac.)

QUESTION 1 The propagation of uncertainty formula for the equation y = ax^2 is (Aya) +(Ayx) where Aya = (ax²) – ((a + Sa)x²).and .Ayx = (ax) - (a(x+ 5x)²) and. The values Sa and 5x are the uncertainties on a and x respectively. If a = -0.7 +/- 0.7 and x = -19+/-0.8 then what is the uncertainty on y? 14.5
