Until the final years of the nineteenth century, the accepted model of the atom resembled that of a billiard ball – a small, solid sphere. In 1897, J. J. Thomson dramatically changed the modern view of the atom with his discovery of the electron. Thomson’s work suggested that the atom was not an “indivisible” particle as John Dalton had suggested but a jigsaw puzzle made of smaller pieces. Thomson’s theory came from his experiments with cathode rays produced by the Cathode Ray Tube. From his experiment, he observed that cathode rays are deflected by magnetic and electric fields in a manner that is identical to negatively charged material. Due to these observations, J. J. Thomson concluded that cathode rays are negatively charged particles that are located in all atoms. When evidence from many new experiments does not support an existing scientific theory like Dalton’s, which of the following is most likely to happen?

Cooperation among oligopolies runs counter to the public interest because it leads to underproduction and high prices. in an effort to bring resource allocation closer to the social optimum, public officials attempt to force oligopolies to compete instead of cooperating. consider the following scenario: suppose that the presidents of two auto manufacturing companies exchange text messages in which they discuss jointly raising prices on their new lines of hybrid suvs. this illegal communication would violate which of the following laws? the sherman antitrust act of 1890 the robinson–patman act of 1936 the celler–kefauver act of 1950 the clayton act of 1914
