Which option below describes the main difference between analog and digital technology?
1)Digital technology reproduces sound more faithfully than analog technology
2)Digital technology records information as strings of "1" and "0" whereas analog records information as continuous waves
3)Digital technology can only record sound, but analog technology can record both sound and images
4)Digital technology relies on electromagnetics but analog technology records information using binary codes

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
