Answer;
Thomson's experiments are important because they showed that the atom is clearly composed of smaller particles.
Explanation;
J.J. Thomson used magnetic and electric fields to measure the mass-to-charge ratio of a cathode ray particle. Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. He proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."
Answer:
1. Watch Mark Rober...He's great!
2. A shark maintains his buoyancy because a shark was the same amount of force pushing awards as gravity is pulling is downwards. So instead of sinking it floats. I know that didn't make a lot of sense but seriously, watch Mark Rober and you will know everything!!! (unlike me, a freshman)
3. P.S. If you want to learn more about buoyancy, I suggest you watch the balls in the liquid sand video
Explanation:
Oxygen was missing in Earth’s early atmosphere
Answer:
It depends on the animal(s)
