y = 0, 3 (Use these values in place of psi). First solve all with 0 and then 3. Use the partial derivative uncertainty equation 1. You are attempting to determine the density of a ceramic cube. The mass of the cube is measured as (5 + w/20.1) g, (+ 0.2 g). The measurement for the height, length, and depth of the cube are equal with H = L = D = (9 + w/502) mm, (+ 3%). Find the density and the uncertainty in the measured density. kg/m' and Ap = kg/m3 2. Assume an ideal op-amp. Let Vin = (2y +20) mV, (+3 mV), Ra = (5+4/20)12 (+ 2%) and Rb = (y+25) $2 (+ 3%). Find V. and the associated uncertainty in V. Vin V out Vout = V AV out = 3. The input voltage is y V, (+ 0.1 V). The values of Va and Vb are read by an Arduino with a 10- 100 0 (+2%) bit A/D converter and a 5.00 V range. The a b values displayed by the LCD are Va = 0.7715 10KQ V and Vb = 0.5908 V. Find the current through the LED and the associated uncertainty. MA Al= mA 4. Repeat Problem 3. However, the voltages are read by a 12-bit A/D converter with a 10.00 V range ( rather than a 10-bit A/D converter with a 5 V range). 1= mA Al = mA 5. Find the uncertainty for the measured speed of a car where the car travels (50 + 10w) ft (+ 2 ft) in (25 + 4/11.2) s, (+ 0.3 s). AV = mph
