Shua!
Everyone in the class turned to look at Yue Pingting and Xu Heng.
"Hahahaha…
hindsight!"
Then, the whole room burst into laughter.
Even Qin Fangming couldn't help but exclaim,"Ha…cough cough! Students, don't laugh! Enough is enough!"
"Student Yue, do you know what you just said?”
"I know!" When I was discussing with Xu Heng just now, I was scolded by him for saying that I was an Antarctic bear.”
She said it very seriously.
There was no falsehood in her beautiful eyes.
Qin Fangming glanced at Yue Pingting, then turned to Xu Heng.
"Xu Heng! You really know this question? Have you seen the same question type before?”
Xu Heng stood up and prepared to follow his teacher's instructions.
But Yue Pingting beat him to it,"Xu Heng said it's such a simple question. What's there to be surprised about?”
Crash!
The entire class was in an uproar.
He looked at Xu Heng and Yue Pingting as if he was looking at monkeys.
Qin Fangming frowned. He had some understanding of Yue Pingting and Xu Heng.
These two people's grades were bad, but they still had character. Moreover, Yue Pingting wasn't stupid, lying wouldn't benefit her at all.
Qin Fang Ming said,"Xu Heng, is what she said true?”
Yue Pingting said confidently,"Every word is true!”
Xu Heng's face darkened.
Now that things had come to this, he could only admit it.
"Yes!"
Powerful and resounding!
The class instantly fell silent, so quiet that one could hear a pin drop.
A bad student had actually solved a difficult problem that had given all the students a headache.
Not only that, he actually said it was easy!
"You're bragging without a draft!"
Many people gritted their teeth.
Especially the physics class representative.”
Qin Fangming was very patient."In that case, come! I'll give you another question!"
Title:
A cat at the table yanks the tablecloth out of the fish tank, but the fish tank doesn't slide off the table. If the dynamic friction factors between the fish tank, the tablecloth, and the tabletop are equal, then (A)
the direction of the tablecloth's friction force against the fish tank is to the left,
(B) the sliding time of the fish tank on the tablecloth is equal to that on the tabletop
,(C) if the cat increases the pulling force, the friction force received by the fish tank will increase, and
(D) if the cat decreases the pulling force, the fish tank may slide off the tabletop.
Qin Fangming even drew a sketch on the blackboard: The kitten was pulling the tablecloth at the corner of the table. There was a fish tank on the tablecloth.
This was a multiple-choice question!
Therefore, if one was careless, even the best student would make a mistake because of ambiguity.
Not to mention the other students.
Many students frowned when they saw this question.
"My head hurts! I feel uncomfortable looking at this question! It was too difficult! There was no way to start! Xu Heng, aren't you very capable? Tell me about it!"
"You don't have any ideas at all! I don't believe that I'm worse than a slacker!”
"The physics teacher is deliberately making things difficult for us!”
"It's not hard on you, but it's hard on Xu Heng!”
"If Xu Heng can answer it, I'll go to the toilet upside down!”
Many people looked at Xu Heng.
Qin Fangming had a look of anticipation.
Xu Heng replied,"B-D."
Qin Fang Ming's heart trembled,"What about the process?”
Xu Heng said,"When the cylinder moves to the right, the friction between the cloth and the cylinder will move to the right, so A is wrong. Then, the sliding friction has nothing to do with the pulling force, so C is also wrong.”
All the students perked up their ears and listened carefully.
But Xu Heng didn't say anything.
Everyone was speechless.
Xu Heng replied,"I'm done."
Everyone was shocked and blurted out,"It's that simple? Is that all?"
This was a rhetorical question!
But Xu Yi's answer was,"It's that simple. It's gone."”
After a while, the students came back to their senses.
"This is a multiple-choice question. Excluding AC, the only one left is PhD! "
Teacher, is his answer correct?”
Qin Fangming's eyeballs almost popped out.
"Another question!"
"The Earth's rotation is gradually slowing down. 300 million years ago, the Earth's rotation period was about 22 hours. "Assuming that this trend continues, the other conditions of the balloon remain unchanged, and the future launch of the Earth's synchronous satellite compared to the present..."
Xu Heng said directly,"The height from Earth has increased.”
This question tested the high orbit, low speed, large cycle, and low orbit, high speed, small cycle.
The speed here referred to the linear velocity, angular velocity, and acceleration. The changes of these three would increase or decrease, so the answer was obvious.
"The question is very simple!"
But Xu Heng's reply was also very rude!
Qin Fangming was speechless. He was like Newton who had discovered gravity, incomparably excited!
This question was easy?
"Again!"
"There is an electric field distributed along the X axis in space. The electric field strength E changes with X as shown below. The following statement is: The
electric potential of point A.O is the lowest, the electric potential of point B
. The electric potential of point X2 is the highest, the
electric potential of point X1 and-X1
is equal, and the electric potential of point X1 and X3 is equal.
" Qin Fangming began to draw.
This was the final question of the college entrance examination. He did not believe that Xu Heng could be so evil.
One had to know that just answering this question would take a lot of time. Not only did it take a drawing, but it also required various assumptions.
It was extremely taxing!
However, just as he was drawing, Xu Heng said,"Choose C.”
Qin Fangming hadn't finished drawing yet.
Kacha!
His chalk broke. He slowly turned around and stared at Xu Heng.
The class was extremely quiet.
The students had all sorts of question marks in their minds.
Did he get it right?
In the next second!
Qin Fangming said,"I'll give you the chalk. Come on stage and speak!”
