Average Uncertainty

AI Thread Summary

To find the average time for the bowling ball, sum the recorded times (2.45s, 2.49s, 2.58s, 2.55s, 2.51s) and divide by the number of trials, resulting in an average of approximately 2.51s. For the car length measurements (4.5m, 4.7m, 4.4m, 4.6m, 4.8m, 4.5m, 4.6m), sum the lengths and divide by seven to obtain an average of about 4.57m. Uncertainty can be calculated by finding the range of the measurements and dividing by the square root of the number of measurements. This approach provides a clear method for determining both average values and their uncertainties. Accurate calculations are essential for reliable results in experimental data analysis.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
