Find the uncertainty in the moment of interia. Moment of interiaof a disk depends on mass and radius according to thisfunction I(m,r) = 1/2 m r2. Your measuredmass and radius have thefollowing uncertainties δm= 0.12kg and δr= 0.07 m. What is is the uncertaintyin moment of interia,δI , if the measured mass, m = 0.39kg and the measured radius, r = 0.25 m? Units are not needed inyour answer.
2. Find the uncertainty in a calculated electricalpotential difference from the measurements of current andresistance. Electric potential difference depends on currentand resistance according to this function V(I,R) = IR. Yourmeasured current and resistance have the following valuesand uncertainties I = 5.9 Amps, δI= 0.4Amps and R = 42.7 Ohms and δR=0.6 Ohms.What is the uncertainty in the , δV? Units are notneeded in your answer.
