Answer 1

Answer:

1)Cathode rays focused on a hard target (anticathode) produce X-rays or focused on a small object in a vacuum generate very high temperatures (cathode-ray furnace). When cathode rays strike certain molecules used to coat a cathode screen, they cause the molecules (and hence the screen) to emit light

2) They travel linearly.

They have a negative electric charge

4) Goldstein

5)mass of electron is 9×10 to the power -28 gm and it's charge is negative

mass of proton is 1.6×10-²⁴ and it's charge is positive

7)

Thomson's atomic model failed to explain how the positive charge holds on the electrons inside the atom. It also failed to explain an atom's stability. The theory did not mention anything about the nucleus of an atom.
