Abicycle wheel has a diameter of 63.2 cm and a mass of 1.89 kg. assume that the wheel is a hoop with all of the mass concentrated on the outside radius. the bicycle is placed on a stationary stand and a resistive force of 123 n is applied tangent to the rim of the tire. (a) what force must be applied by a chain passing over a 9.02-cm-diameter sprocket in order to give the wheel an acceleration of 4.43 rad/s? 880.35 (b) what force is required if you shift to a 5.62-cm-diameter sprocket? 1412.95x your response is off by a multiple of ten.

Apossible explanation for a set of facts that can be tested by further investigation is called

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.)
