a cathode ray tube is made of glass with a small amount of some kind of gas in it. it has metal electrodes at each end to pick up an electric current. the electrodes are named \positive\ and \negative\. what are one of the main uses of this device?\n○ to speed up the flow of current flowing through a wire\n○ to examine a beam of charged particles\n○ to magnetize different atoms within a space\n○ to change the strength of a proton within an atom

Answer

Brief Explanations:

A cathode - ray tube is used to study charged - particle beams. It creates a controlled environment where the behavior of electrons (charged particles) can be observed and analyzed. The other options are not the main uses of a cathode - ray tube. Speeding up current in a wire is not its function, magnetizing atoms is not its main purpose, and changing the strength of a proton within an atom is not what it does.

Answer:

to examine a beam of charged particles
