Seeing that Cheng Biting Tie was so enthusiastic, the classmate was embarrassed to refuse, and directly picked up the question and began to read it.

The formation of the absolutist centralized political system of the Qin Dynasty, "Cheng Biting Tie, are you sure this is a physics question, not a history question?" ”

The classmate shook his head and scratched his head, no matter how good you are at physics and give you a history problem, then you may not be able to solve it.

"Show me!" Before Cheng Yantie could react, he directly took the book away. Sure enough, the history workbook is a compulsory one. It's over, and if I continue like this, I probably won't even know what I'm called.

Putting down history, Cheng Biting Tie picked up a book again. This time, after he personally determined, it was a physics problem.

When Cheng Bingtie picked up the physics workbook, Liu Bingqing came back. It seems that the recess exercise has just ended.

"Cheng Biting Tie, what are you doing with my book? Don't you know that it is very rude to take a girl's book without permission? Liu Bingqing said, habitually brushing the hair that was blocked in front of his forehead, "Especially a beautiful girl like me." ”

After hearing Liu Bingqing's words, Cheng Biting obediently returned the book to her. I have a crush on classmate Liu Bingqing, yes, I must not make her angry.

Cheng Biting Tie looked at Liu Bingqing's ladylike figure sitting in his seat, and what he thought at this time was whether he would be able to see her again a year later. Liu Bingqing's liberal arts grades are among the best, and he is following the advice of his parents and preparing to study science. Perhaps, in a year's time, we will all have the best home.

Forget it, before next year's college entrance examination, I must confess to Liu Bingqing. Otherwise, you may not be in the same class in the future. Liu Bingqing, but Cheng Biting Tie's first and only crush on the girl, there are not many pure girls like this.

Cheng Biting Tie is now very remorseful, why didn't he meet Liu Bingqing a long time ago, God's will is hard to disobey!

"This is limited to 5 minutes." Although it is not wrong that he has a crush on classmate Liu, it is also urgent to rescue Liu Xianying from the magic star spell witch.

As soon as the student looked at the question, he frowned, as if he had eaten a rotten egg. Looking at his appearance, Cheng Biting Iron next to him was also very worried, whether he would do it or not. This type of question is what Mr. Yang used to talk about in class.

As shown in the figure, the weight of the object is 30N, and the maximum tensile force that can be withstood by the OC rope is 20√3N, and then the maximum tensile force that the BA rope can withstand is 30N. With the current horizontal force to pull BA, how much angle can the OA rope be pulled to the vertical direction?

"Is it on board?" Li Hu asked Wang Xiangdao, take advantage of the recess exercise, qualifying.

"Ascended, qualifying began to match." Wang Xiang slapped his thigh, picked up a bottle of drink on the table, and drank it in a big gulp. "Li Hu, Han Xin is an assassin, you go over from the middle lane, prepare to fight the jungle, and I'll go down. Wait for the microphone to turn on, and I'll teach you how to play. ”

"Okay." Li Hu smiled, the glory of the king is good, when I learn it, I am ready to bring a young lady to play together.

Wang Xiang didn't know what Li Hu thought, if he knew, he would probably squirt out all the Coke he had just drunk. It's just you, take the young lady to open the black, don't take the young lady into the pit, thank God.

Looking at the 5V5 matching interface, Wang Xiang sighed, although it was only 30 seconds, but for Wang Xiang, who is keen on games, it was like spending a century.

The classmate took out a draft book that he had treasured for many years and began to draw.

A line in the vertical direction, the line catches a 30N heavy object, the fixed end of the rope is represented by the letter O, and the end in contact with the weight is represented by the letter C. In addition, tie a rope to point A on the OC rope, and pull the BA rope to the right under the action of horizontal force, the question is what is the angle between the OA rope and the OA' rope? If you let Niu Zihao solve this problem instead, do you still use drawing, it is estimated that you don't even need to write the problem-solving process, and the answer will come out. There's no need at all, your brain is just a piece of white scratch paper. Any calculation, as long as it passes through the rigorous brain of the top student, will output the most correct answer.

Cheng Yantie didn't dare to look at physics questions at all, and as soon as he saw this kind of question, he immediately had a headache. When I took the high school entrance examination, I not only had a headache, but also hurt all over my body.

The classmate held a pen, scratched his head, rubbed his eyes, twisted his waist, and moved his muscles. Half a day passed, and I didn't see him write a word on the scratch paper, just drew a picture and marked a few letters. Sometimes, Cheng Biting Tie also wonders if he is a scholar. Scholars don't all pick up the pen and write down a lot of formulas that others can't understand. This is Xueba, a typical king of brushing questions.

Seeing that the countdown to the match had been counted, Li Hu and Wang Xiang glanced at each other, and the two smiled, and the next step was the qualifying match.

It is said that it is a smile, but in fact, it is just a knife hidden in a smile. Former teammates may be future enemies. It's an enemy, it's a teammate, just a thought. No matter who you come across, protecting your crystals is the most important thing.

The enemy has 5 seconds left to reach the battlefield, so be prepared.

Holy Sword, do you see that enemy?

The familiar melody echoed in their ears, and Li Hu and Wang Xiang were addicted to the game and couldn't help themselves.

Cheng Biting Tie and the others were almost asleep, but suddenly heard someone beating the king in the classroom. If you fight the king, you will fight, and no one will say that you will not be allowed to fight, what is the matter with your voice being so loud, affecting others to learn or not.

"Wang Xiang, Li Hu, keep your voice down, if you don't study, don't affect other students." Cheng Biting reprimanded the two classmates like a class bully, which also made many girls in the class look at them with admiration.

In my life, having such a boyfriend is actually quite good and very secure.

The classmate was still working on the problem, and he was so anxious that he scratched his ears and cheeks, but there was no way to solve the problem.

If you want to talk about Wang Xiang, it will be even worse. The amount of blood that was hit by one of the enemy's big moves was almost gone, and when I returned to the city, I was attacked by Sun Shangxiang, who was already hiding in the grass, and I lay down directly, and I died. Waiting for 17 seconds is not a problem, but the problem is that our crystal is being attacked, and Wang Xiang is very uncomfortable to hear.

"Request for support, Li Hu, retreat quickly, the crystal is attacking." Wang Xiang sent out his last cry for help.

At this critical time, Li Hu's mobile phone was out of battery and automatically turned off!
