Y= You are attempting to determine the density of a ceramic cube. The mass of the cube is measured as (5 + p/20.1) g, (+0.2 g). The measurement for the height, length, and depth of the cube are equal with H = L = D = (9+ 4/502) mm, (+ 3%). Find the density and the uncertainty in the measured density. P = . kg/m3 and Ap = kg/m3 1) Assume an ideal op-amp. Let Vin = (2y +20) R mV, (+3 mV), Ra = (5+y/20)$2 (+ 2%) and Rb = (y+25) $2 (+ 3%). Find V. and the associated uncertainty in V. Vin Vout Kaut = V Vant = 2) The input voltage is y V, (+ 0.1 V). The values of Va and V. are read by an Arduino with a 10- + 100 9(+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. 1 = MA AI = MA 3) 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). MA Al = MA 4) Find the uncertainty for the measured speed of a car where the car travels (50 + 10y) ft (+ 2 ft) in (25 + 4/11.2) s, (+ 0.3 s). AV = mph
