Which of the following provides evidence to support thomson's hypothesis about electrons?
gold foil experiment
cathode ray experiments
spectrum of colors emitted by gas
radiation produced when beryllium is bombarded with alpha particles

The answer is: Cathode ray experiments.

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.

Explanation:

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
