Fig. 5. (Color online) Plot of the resistance coefficient c vs. the ball radius R. The error bar indicates the standard deviation. The data points without noticeable error bars have standard deviations too low to see. The data from the metal ball without a shell was excluded from the trend line, due to its nonspherical shape.
