In Fig. Figure 18.9 shows the results of one of the observations of the migration of a Brownian particle. Observations were carried out every 30 s, the water temperature was about 25 °C, the radius of the Brownian particle was 4.4·10-7 m. Having measured the “steps” of the particle on a given scale, find the square of the mean square displacement for a certain time, calculate the Boldmann constant and Avogadro's constant. Scale: 1 mm in the figure corresponds to a displacement of 1.25 µm.
