Answer 1

Answer:

1. Robert brown noticed that pollen is in constant random motion, while he placed the pollen grain in a glass slide with water to prepare a wet mount.

2. Einstein proposes that the constant randommotion of the pollen grain is caused by the movement of invisible particles of water that collides with the pollen grain from a random position.

3. Einstein has proved his proposition mathematically through his Theory of Relativity(E=mc square).

4. Robert brown was named as the particle motion.

Explanation:

hope this helps!!

Answer 2

${\large{\pmb{\sf{\underline{Required \; Solution...}}}}}$

Question 1. What did Robert Brown observe about the pollen?

Answer 1. Before observing about pollen grains, he placed pollen grains in a glass slide with water to prepare a wet mount. Then he starts observing it under a microscope while observing he noticed that pollen is in constant random motion.

Question 2. What proportional did Einstein make about the constant random movement of pollen grains?

Answer 2. It is caused by the movement of invisible particles of water that collids with the pollen grains is that proportional, Einstein made about the constant random movement of pollen grains.

Question 3. How did Einstein prove his proportional?

Answer 3. Einstein prove his proportional in mathematical way not in a logical way. He prove it as E = mc² It is formula of "Theory of Relativity".

Question 4. To whom is the particle motion named?

Answer 4. To Robert Brown, the particle motion named. Nowadays It is known as Brownlain Motion.

Henceforth, we have done! Hope it's helpful!
