Dear Scientist in physics , How are doing, my name is Yahya from Saudi Arabia and currently in my first semester to pursue Master's degree in physics. I have been watching all interviews of some scientists in physics on YouTube Channel and somthing has got my mind. I studied my bachelor 's degree in biology and I have been contacting Professor's Bruce Lipton many times and he explained epigenatic well. He was talking about physics many times. He said if you want to understand who we are and how we think, you need to understand Physics well. So I have decided to study physics. I have some questions : Why is the community of physics are divided? What is the difference between Quantum physics, quantum field theory, Quantim theory, and classical physics? What is quantum consciousness theory as well. What do they mean by wave function collapse? Why professor Roger's always has another opinions in quantum consciousness theory?? Best Regards, Yahya

Given water's mass of 18g/mole and the value of the fundamental charge (charge magnitude of the electron and proton), use the largest charge density from the article to determine what fraction of water molecules became ionized (charged) due to triboelectric effects when it flows through the material that causes the largest charge transfer. Give your answer in e/molecule, or electrons transferred per molecule of water. For instance, a value of 0.2 means only one in five molecules of water loses an electron, or that 0.2=20% of water molecules become charged

The ratio of the number of molecules in Coma Cluster and the molecules in the Milky Way galaxy is calculated as,

$mgn=400 cm −33.56× 10 −6 cm −3mg=(1.12× 108)n$

The ratio of the number of molecules in Coma Cluster and the molecules in the corona of the Sun is calculated as,

$msn= 105 cm −33.56× 10 −6 cm −3ms=(2.8× 10 10)n$

Conclusion:

The number of molecules in the Earth’s atmosphere per centimeter cube is $8.4×1024$ times the number of molecules on Coma Cluster.The number of molecules in the Milky Way galaxy per centimeter cube is $1.12×108$ times the number of molecules on Coma Cluster. The number of molecules in the corona of the Sun per centimeter cube is $2.8×1010$ times the number of molecules on Coma Cluster.

Answer 21

To determine

(c)

The comparison between the intracluster gas in the Coma Cluster with the gas in the atmosphere, a typical gas cloud in our own galaxy and the corona of the Sun.

Answer 26

Explanation of Solution

Given:

The number of molecules per centimeter cube in Earth’s atmosphere is, $me=3×1019 cm−3$ .

The number of molecules in the typical gas cloud in the Milky way galaxy is, $mg=400 cm−3$ .

The number of molecules in the corona of the Sun is, $ms=105 cm−3$ .

Calculation:

The ratio of the number of molecules in Coma Cluster and the molecules in the Earth’s atmosphere is calculated as,

$men=3× 10 19 cm −33.56× 10 −6 cm −3me=(8.4× 10 24)n$
