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

The correct answer will be option A-the accepted model of the atom was changed.

Explanation:

J.J Thomson discovered the electrons by cathode ray tube experiment in 1897 and realized that the accepted model of atom as proposed by the Dalton has problems as he stated that "atom is indivisible".

The discovery of sub-atomic particles-electrons in his experiments showed that the atom can be divided into sub-atomic particles and he proposed the pudding model of the  atom which changed the accepted model of atom at that time.

Thus, option A-the accepted model of the atom was changed is the correct answer.

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
