A particle with charge 3.20 x 10^?19 C is placed on the x axis in a region where the electric potential due to other charges increases in the +x direction but does not change in the y or z direction. Part A:The particle, initially at rest, is acted upon only by the electric force and moves from point a to point b along the x axis, increasing its kinetic energy by 1.60 x 10^?19 J. In what direction and through what potential difference Vb-Va does the particle move?a. The particle moves to the left through a potential difference of Vb-Va = 0.500 V. b. The particle moves to the left through a potential difference of Vb-Va = -0.500 Vc. The particle moves to the right through a potential difference of Vb-Va = 0.500 V. d. The particle moves to the right through a potential difference of Vb-Va = -0.500 V. e. The particle moves to the left through a potential difference of Vb-Va = 5.00 V. f. The particle moves to the right through a potential difference of Vb-Va = -5.00 V. Part B:If the particle moves from point b to point c in the y direction, what is the change in its potential energy, Uc-Ub?a. + 1.60 x 10^?19 Jb. - 1.60 x 10^?19 Jc. 0

Use the frequency histogram to complete the following parts. ​(a) identify the class with the​ greatest, and the class with the​ least, relative frequency. ​(b) estimate the greatest and least relative frequencies. ​(c) describe any patterns with the data. female fibula lengths 30.5 31.5 32.5 33.5 34.5 35.5 36.5 37.5 38.5 39.5 0 0.05 0.1 0.15 0.2 0.25 length (in centimeters) relative frequency a histogram titled "female fibula lengths" has a horizontal axis labeled "length in centimeters" from 30.5 to 39.5 in increments of 1 and a vertical axis labeled "relative frequency" from 0 to 0.25 in increments of 0.05. the histogram contains vertical bars of width 1, where one vertical bar is centered over each of the horizontal axis tick marks. the approximate heights of the vertical bars are listed as follows, where the label is listed first and the approximate height is listed second: 30.5, 0.02; 31.5, 0.04; 32.5, 0.05; 33.5, 0.13; 34.5, 0.22; 35.5, 0.25; 36.5, 0.13; 37.5, 0.06; 38.5, 0.09; 39.5, 0.01. ​(a) the class with the greatest relative frequency is nothing to nothing centimeters. ​(type integers or decimals. do not round. use ascending​ order.)
