The figure, shows the dot and whisker plot of measured value and uncertainties from Group A and Group B for a same experiment assigned for both groups. Which group did better job on collecting data provided they are using same equipment? Uncertainty bars of Group A and Group B +B 1 1.2 1.4 1.6 1.8 Group B, because the uncertainty on their data is largest

Let A = 2 x2y3Where x= 16 ± 0.5 and y = 9 ± 0.3Please find the nominal value of A and the uncertainty in this term.

Find the uncertainty in the moment of interia. Moment of interia of a disk depends on mass and radius accordng to this function I(m,r) = 1/2 m r. Your measured mass and radius have the following uncertainties Sm = 0.34 kg and Sr = 0.17 m. What is is the uncertainty in moment of interia, %3D S1 , if the measured mass, m 6.05 kg and the measured radius, r = 14.74 m? Units are not needed

Can you please explain how to solve the uncertainty for this problem. I previously asked the same question but the answer for the uncertainty i was given is wrong +/- 0.00559

A marathon runner completes a 42.188-km course in 2 h, 35 min, and 39 s. There is an uncertainty of 28 m in the distance traveled and an uncertainty of 1 s in the elapsed time. (Give all answers to the appropriate number of significant figures. Note that uncertainties should be reported to one significant figure and percent uncertainties should be reported to two significant figures.) (a) Calculate the percent uncertainty in the distance. _________% (b) Calculate the percent uncertainty in the elapsed time. __________%

For questions (1) – (8) use the following information. You have measured the length of a table to be 205.0 cm, 205.8 cm, 205.4 cm, 204.6 cm, and 204.9 cm five independent times. You measured the width of the same table to be 60.1 cm, 60.4 cm, 60.2 cm, 60.0 cm, and 60.5 cm five independent times. 1) Calculate the mean length L of the table. 2) Calculate the standard deviation of the mean length σ of the table. 3) Calculate the mean width W of the table. 4) Calculate the standard deviation of the mean width ow of the table. 5) Calculate the area A = L x W of the table. 6) Using the correct equation for propagation of error, calculate the uncertainty of the area OA of the table.
