Chapter 133 Serial fart (for subscription)
"Then you don't have to worry about it. The Chen Chao I'm talking about is Chen Chao, and Zhang Yangyang is Zhang Yangyang. They're not my students. Besides, there are so many people with the same name in the country. I'm really not talking about you. Go online and search on Baidu. There are a lot of names." The physics teacher joked.

The physics teacher has already said so, what else can Chen Chao and Zhang Yangyang say?I can only blame myself for not covering my mouth. I don't know that it is better to talk less in the physics teacher's class.

However, it is precisely because of the physics teacher’s teaching style that the average physics score of the three classes of Senior [-] (Five), Senior [-] ([-]), and Senior [-] ([-]) is at the highest level in the year, because this is what he teaches The level of physics scores in the three classes he teaches is obvious to all, and they are very popular among the students.

In terms of physics, he has been rated as a model teacher all year round.

"Okay, students, now let's continue with the topic just now. Don't underestimate this shit. The average person who wants to step on shit doesn't have this luck. You all know that shit luck, shit luck, right? Sometimes shit Luck is so lucky, but, what I want to say is that classmate Chen Chao didn't really step on dog shit, he stepped on a piece of advertising paper covered in dog shit, and this piece of advertising paper floated to the The soles of Super Chen's feet stuck to them stubbornly, and even laughed at Super Chen, "You want to get rid of me?"

"Zhang Yangyang said, we all know that there is a thing in physics called 'universal gravitation', which was invented by Newton, awesome."

"Chen Chao, who is stepping on the advertising paper covered in shit, speaks at this moment. The coefficient of gravity is negligible, and F is proportional to mass. Zhang Yangyang, you are heavier than me, so have you stepped on it?"

"Zhang Yangyang said, it depends on the distance product!! I'm far away from it, probably..."

At this time, the physics teacher looked at the students below and said, "Okay students, let's imagine that at the same distance from the advertising paper covered in shit, that is, Chen Chao and Zhang Yangyang are standing at the same waist. At the top of the triangle, will this piece of paper fly towards Chen Chao or Zhang Yangyang in the end? The premise is that the two of them are equidistant, and the shit piece of paper has not been stepped on by Chen Chao. Students , use your imagination, and tell me the answer."

"What are the hidden factors that affect whether this shit-stained advertising paper will eventually fly to Chao Chen or Zhang Yangyang? Can any students give me some ideas? Let go of your thinking, imagine boldly, and use science to verify."

At this time, a girl in the class raised her hand.

"Huang Xin, please answer."

The physics teacher called the female student who raised her hand.

Huang Xin stood up, and then said, "Teacher, there are many influencing factors. For example, the cross wind blowing from the left and right sides of the two people may also be caused by the positive and negative charges brought by the clothes on the two people. size, and of course the law of gravitation, could cause a piece of shit-stained advertising paper to fly toward one of them."

The physics teacher nodded, motioned Huang Xin to sit down, and then said, "The three conditions Huang Xin said are all correct, and they can all affect this piece of advertising paper. Among them, the horizontal wind has the greatest effect because the wind is strong, and the wind is strong. The force-receiving area of ​​paper is also large. If it is calculated according to the buoyancy, no matter which side it blows from, it may blow to another person. The positive and negative charges are also one of the influencing factors, but this factor can be ignored. Regardless, because the electric charges produced in the human body are positive charges, and there is a lot of water in the human body, the water is uncharged, and the positive and negative charges in the human body cancel each other out. What is in the negative charge is to neutralize it, and the human body will not be charged.”

"Then teacher, sometimes when we touch doorknobs or other things with our hands, we suddenly feel paralyzed. What's going on? Doesn't it mean that the human body is not charged?"

The physics teacher nodded and said again, "That's because there is a potential difference between the person and the doorknob, and an instantaneous discharge will occur, and the air molecules will be ionized into ions, that is, positive ions and negative ions."

"Oh."

The student nodded.

The physics teacher said again, "Similarly, even if people are negatively charged, the amount of charge they carry is different, resulting in different potentials, which will also cause discharge phenomena, but these phenomena cannot affect it too much. The distance is too great."

"Students, let me ask you, besides these, are there any other phenomena that can change this change?"

"Teacher, if one of them farts and changes the pressure, then the place with high pressure will change to a place with low pressure, so it is possible to make the advertising paper fly towards someone, right?" At this time, A laugh came from behind.

When this possibility was brought out, there was a roar of laughter.

"Ha ha ha ha."

"Killing me……"

"Who the hell is so talented? Can you even think of this? Fart? Hahaha..."

The physics teacher was taken aback, but still said, "Yes, the possibility that this student mentioned is not impossible. For example, typhoons often hit our southern coastal areas, and that is because when summer comes, tropical seas are affected. Direct sunlight increases the temperature of the sea water, and the evaporation of the sea water provides sufficient water vapor. The water vapor condenses during the uplift, releasing a large amount of latent heat, which promotes the further development of convective movement, causes the air pressure at sea level to drop, and causes the surrounding warm and humid air to flow in. Supplement, and then lift again, due to the high-speed rotation of the earth from west to east, resulting in friction between the air column and the surface of the earth, because the closer to the equator, the stronger the friction."

"In tropical or subtropical oceans where the sea surface temperature exceeds 26, due to the high temperature near the ocean surface, a large amount of air expands and rises, which reduces the air pressure near the ocean surface, and the peripheral air continuously replenishes and inflows upward. Influenced, the inflowing air rotates. The ascending air expands and becomes colder, and when the water vapor in it cools and condenses to form water droplets, it releases heat, which makes the lower-level air continue to rise. In this way, the air pressure near the ocean surface drops even lower, and the air rotates more violently , and finally formed a typhoon, and the influence of the typhoon is naturally far stronger than that of the crosswind, and it is even possible for two people to be stained with the advertisement paper, but a single person cannot produce such a large jet."

"Why not? Assuming it's a chain fart, loud and loud?"

From behind, the same doubts came out again.
