Which best describes the effect of j. j. thomson’s discovery? the accepted model of the atom was changed. the accepted model of the atom was supported. cathode ray tubes were no longer used in experiments due to poor results. cathode ray tubes became the only instrument of use in the study of atoms.

answer is A the accepted model of the atom was changed

Answer is: the accepted model of the atom was changed.

J.J. Thomson placed two oppositely charged electric plates around the cathode ray. He did experiments using different metals as electrode materials and found that the properties of the cathode ray remained constant no matter what cathode material he used.

Tomson concluded that atoms are divisible and that the corpuscles are their building blocks (atoms are made up of smaller particles).  

J. J. Thomson discovered the electron in 1897.  

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.  

With this model, he abandoned his earlier hypothesis (the atom was composed of immaterial vortices).  

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
