Answer:
New experimental processes provide new scientific evidence
Explanation:
Thompson experimented on the cathode rays but Rutherford's experiment was more expanded and perfectly visualized. When Henri becquerel found the evidence of radioactivity Rutherford went on this experiment using alpha rays but what's interesting is if becquerel dint found any evidence about radioactivity Rutherford would never find about atomic particles. So the answer would be New experimental processes provide new scientific evidence.
Science changes everyday scientists find facts and in a snap other scientist proves that information is wrong. That 's how the science build up. It starts by trying things until its the right one.
