This is a knowledge point in the second section, and yesterday I just entered the first section.

But in fact, this common sense was mentioned in the physics textbooks in junior high school. The reason why physics teachers asked such a simple question was to see if Yang Fan was the kind of person who really came in through the back door.

After all, if you really come in based on your own grades, you naturally won’t even know the simplest thing.

"Okay! You have passed the test. Since you already know the speed of light, then I want to ask, how many meters does the distance light walk in a year?"

The distance that light walks in a year is actually described as one unit, which is one light year.

"This! It's very simple! Using the formula learned in the second section, the displacement x=v?t can be calculated. The propagation speed of light in the vacuum is 3.0×10 cubic meters per second, and multiplied by the time of one year 365×24×3600=3153600s, so the final result of the distance that light travels in a year should be 9.46×10 cubic meters, right? Teacher!"

“…”

When Yang Fan said something, the classroom was silent like death.

The speed of light propagation in a vacuum is actually a relatively common knowledge point. It was learned before, and people with a light-year-old thing should have seen it online.

But now it is not only Yang Fan who has told these four results, but the most important point is that he also uses the knowledge points of the formula learned in the second section to solve them step by step, which is completely different from the results he said directly.

Although many students have previewed the textbooks and the knowledge points they need to learn, they really haven't read it too seriously.

Not to mention doing these calculation questions.

Because yesterday's homework has already put them in a slight sluggish manner, they don't have much extra time to review, otherwise, it would be very simple to solve this problem.

But it is already very clear that Yang Fan was able to say all these things in such a short time.

After all, he was the most famous top scorer in the middle school entrance examination, and this thing was naturally not calculated temporarily.

Instead, he had already previewed the knowledge points of the physics textbooks long ago. He had already learned the knowledge points of several chapters in advance. Even the exercises after class have been solved by himself. So when the physics teacher asked this question, he could actually tell the answers immediately, but in order to prove that he was not confused, he still told the answers directly.

"Okay! Your name is Yang Fan, right?"

When the physics teacher heard this, he nodded.

"Then you can sit down now, and from now on you will be my physics class representative."

“…”

Yang Fan was very depressed and sat down directly. How could he answer two questions and become a physics class representative?

Not only was he confused, but even other classmates were confused.

Because in fact, these two questions are not too difficult at all. The first is common sense, which most people know, and the second question, even if you don’t know, you can calculate it if you give them some time.

But there are only two simple questions. Did Yang Fan directly serve as a physics class representative?

Of course not. The physics teacher has known the name Yang Fan for a long time. In fact, it is not just a physics teacher. Even other subject teachers have heard of his name for a long time, but they don’t know who it is.

It is only because of these two simple questions that it is naturally impossible for him to be a physics representative, but the physics teacher has seen that Yang Fan’s high school entrance examination scores are full marks in physics.

In addition, a perfect answer to yesterday's homework was actually not just a physics teacher, but other science teachers also had the idea of ​​letting Yang Fan be his own class representative.

It’s just that this action was first implemented by the physics teacher.

"I'm throwing it away! You're so crapy. When did you go to class? You didn't even call me?"

Yang Fan looked at Lin Ranran who was listening carefully next to him and complained speechlessly.

He just lie on the table and sleeps during get out of class break, but he didn't hear the bell ringing for class. The key is that Lin Ranran next to him did not call him, which is what made him most depressed.

"Tsk! Anyway, your grades are so good, so it's the same to listen to the class! What am I asking you for?"

Lin Ranran looked at him with a look of perverted look, stopped talking, but continued to listen to the class.

...

When he was studying at night, he returned home quickly.

After all, in addition to the things that Qingning and the others had told him, he also wanted to go home and get some points.

"By the way! I'm home now. Have you agreed? When will it start?"

He sent another message to Qingning to confirm whether he could fight?

If he can't fight, he will get a score. After all, the diamond rank of this account is indeed too low.

"Okay! Then I'll talk to them and make sure the time."

Qingning replied, there was no movement.

They had already agreed before in the group, and now the most important thing is to check with Gou Chen.

He, Qingling, Fireworks, Lan Shang, and Ling. Among them, there is no national standard, but in fact, only Ling, who he is not very clear about.

In addition, a few people are all in the same group. Basically, they get together all day long when they have time. If they really want to cooperate, there is not a single thing.

So there is no need to say more about how strong the combat power of these people gathered together.

"King God, there's no problem. It starts in ten minutes. Then I'll post a link in the group, and you can just go to the account."

Seeing the news from Qingning, he nodded as well.

Ten minutes later, the group of five of them was sent directly, and a link to the room was invited.

Yang Fan also clicked in without hesitation and entered the room.

At this time, there were about seven or eight people in the room.

Yang Fan looked at these strange accounts and typed in confusion for a moment, "I'll lose it! Who are you? Why don't you play with your own big number?"

However, it would be fine if he didn't type. As soon as he typed, a rank of his account Eternal Diamond was instantly exposed.

"Puff! Hahaha! You guys are too low, right? It's better if you can't find your teammate, you can't pull a diamond to make up the numbers?"

When the people from Gouchen saw this scene, they almost burst into laughter.
Chapter completed!
