What did j. j. thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment? the stream of cathode ray particles was moving very slowly. the glass opposite of the negative electrode started to glow. the electric voltage had little effect on the stream of particles. the tube contained two pieces of metal that served as electrodes.

I just took the test its B. The glass opposite of the negative electrode started to glow.

Answer;

The glass opposite of the negative electrode started to glow

Explanation;Thomson discovered electrons as subatomic particles of an atom in a series of experiments designed to investigate the nature of electric discharge in a high-vacuum cathode-ray tube. From these experiments Thomson discovered that cathode ray was made of electrons.The cathode ray tube used by Thomson was a sealed glass container where two electrodes, the positive and the negative electrode, were separated by a vacuum. When voltage was applied across the electrodes, cathode rays were produced such that a glowing patch was created where they stroked the glass seal at the opposite end of the cathode ray tube.

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
