Super Xueba: Start With A Low Control Score!

Multiple choice questions.

"The three cars A, B, and C pass through a certain road sign at the same speed. After that, car A keeps moving in a straight line at a constant speed. Car B accelerates first and then decelerates. Car C decelerates first and then accelerates, but they pass the next road at the same speed. ,but……

(A) Car A passes the next road sign first.

(B) Car B passes the next road sign first.

(C) Car C passes the next road sign first.

(D) Three vehicles arrive at the next road sign at the same time. "

"Da da da da..."

Xie Hongwei quickly wrote this question on the blackboard.

At first glance.

It seems quite simple.

but……

The brows of many children's shoes underneath are tightly furrowed.

"F*ck, labor and management are dizzy."

"Like the devil released from hell."

"It's speeding up and slowing down again. I hate this the most. I have a headache. I don't have any thoughts!"

"Isn't Jiang Nan awesome? Hurry up and have a look, I don't believe it, you will do this question too?"

"..."

Many people turned their attention to Jiang Nan.

certainly……

They are all thoughtless children's shoes.

For example, Qin Yumo, the class leader, and Bai Yingying, who are good at school, immediately took out the draft paper to prepare for the calculation.

Obviously...

They still have ideas.

but……

Did not wait for them to write.

Jiang Nan suddenly said, "The answer is B."

Wow!

When this remark came out, everyone was shocked.

this……

Is the speed too fast?

Don't look at it for a long time, in fact, only a moment later, the physics teacher on stage just finished writing the question.

But the result...

Did Jiang Nan tell the answer?

This is incredible, right?

real?

Still fake?

Swish!

Suddenly, everyone present turned their curious eyes to the physics teacher Xie Hongwei on the stage.

To this.

Xie Hongwei nodded directly, "The answer is right."

Wow!

Hearing this, the audience was shocked again.

"this……"

"Jiang Nan did it right again?"

"How is it possible? Why is he so good?"

"Remember that he used to have very average physics scores! He couldn't rank well in the class at all, but now..."

"..."

The surrounding children's shoes are all shocked, and their faces are all incredible, including people who are familiar with Jiang Nan.

At the same time.

On the stage, Xie Hongwei was also surprised.

Not surprised that Jiang Nan would do this question.

after all……

In his opinion.

This question is not difficult. The test is about the basics of physics. There should still be a lot of children's shoes that the class will make.

But what surprised him was that before Qin Yumo and other academic tyrants had time to write, Jiang Nan gave the answer?

This speed...

Either Jiang Nan is Mongolian.

Or Jiang Nan has done this before.

If neither of these are.

That represents Jiang Nan's profound physical foundation, far surpassing those of academic masters like Qin Yumo.

this……

is it possible?

"Tell me about your problem-solving ideas?"

Xie Hongwei stared at Jiang Nan with scorching eyes.

Jiang Nan: "It's very simple, the three vehicles have the same displacement, the average speed of B is the fastest, and naturally the second is the least time-consuming."

Many students are about to listen upright.

but……

Jiang Nan stopped abruptly.

Everyone: "Go on!"

Jiang Nan: "It's over."

"Nani? It's that simple, no more?"

Everyone's eyes were dumbfounded, and there were big question marks hanging on their foreheads, and they couldn't react.

The displacement is the same.

But why does car B have the fastest average speed?

You make it clear!

but……

Jiang Nan just waved his hand, "It's that simple, it's gone."

Everyone was speechless, as if doing that kind of thing, just rushed to the door, but couldn't get in, panicking.

No way, everyone can only look at Xie Hongwei on the stage, "Teacher, is Jiang Nan's thinking right?"

"right!"

Xie Hongwei spit out a word vigorously.

After finishing speaking, he ignored everyone, and said to Jiang Nan vigorously: "Come on, continue to the next question!"

Multiple choice questions.

"A cup of thick orange juice just won't overflow after adding ice cubes. If the ice cubes are completely dissolved, the orange juice in the glass...

(A) Will overflow.

(B) The liquid level drops.

(C) It still happens to not overflow. "

Xie Hongwei just finished writing the inscription.

Jiang Nan said directly: "A will overflow."

There is a pit buried in this question.

Many people only consider density.

Considering that ice has a small density and large volume, while water has a large density and small volume, the answer is B.

But in fact……

The ice is floating on the thick orange juice, and a piece of it is exposed on the water, so it will overflow when it dissolves.

In physical words.

This test is a deep understanding of Archimedes' principle.

Many children's shoes are very dumbfounded.

But for Jiang Nan, it's pediatrics.

"Yes, come again!"

The physics teacher Xie Hongwei on the stage was shocked again. After all, this time Jiang Nan answered in seconds. It was really amazing.

but……

He is not someone out of stock.

The question continues.

Multiple choice questions.

"In the atmosphere, put a circular simple cylinder with a volume of 0, 50m^3, one end closed and one end open, the bottom facing upwards, and the simple mouth facing downwards, into the pool vertically, and then let go..."

"At equilibrium, the volume of air in the cylinder is 0, 40m^3, and assuming that the pressure of the atmosphere is the same as the pressure produced by a 10m high water column, the height difference between the inside and outside of the cylinder is..."

"..."

Xie Hongwei has not had time to write the options.

but……

Jiang Nan directly said: "2, 5m."

Answer in seconds.

It's all in seconds.

The kind that didn't think much about it at all.

It can be described as simple and rude.

To know……

Even Qin Yumo, a top-notch student, hadn't understood the problem, let alone solved it.

this……

Everyone present was stunned.

Quiet.

Deathly quiet.

No one in the class dared to speak, but stared at the physics teacher on the stage with big eyes like copper bells.

They want to know...

Is Jiang Nan's answer right or wrong?

At the same time.

"Crack!"

On the stage, the chalk in Xie Hongwei's hand suddenly broke into two pieces, because he was also taken aback.

If he hadn't cared about the teacher's face and qualities, he really wanted to scream up to the sky, "How can this be possible?"

This is a preliminary test question for a certain physics competition! The kind that is harder than the finale of the college entrance examination.

From the previous two questions, he has been able to confirm that Jiang Nan's foundation is very deep, and the ordinary questions may not be difficult for the other party.

so……

I deliberately made a competition question.

But the result...

Jiang Nan answered in seconds directly with mental arithmetic?

This is simply going against the sky, okay!

Do you want to be so awesome?

Even him, a senior physics teacher, and the author of the question, have to say admiration!

"Jiang Nan!"

"It surprised me that."

"I have been teaching a book for 30 years, and even when I look at it, you have a very good physical foundation."

Xie Hongwei didn't say whether the answer was right or wrong, but looked at Jiang Nan in a complicated way and slowly praised him.

but……

This is enough.

Jiang Nan's answer is definitely correct.

To this.

There were so many children's shoes, all of them were so shocked that their eyes fell off, and they vomited inwardly: "f*ck, fucking!!!"

However, I am uneducated.

Sentence to lie in the world.

This is the resonance of everyone present at the moment.

No other words.

Four questions in a row.

They didn't know anything about it, just like reading a book, but Jiang Nan answered it easily.

It's not on the same level at all!

Gangster!

Are you still missing a pendant on your lap?

Please take my brother's knees!

Everyone looked at Jiang Nan's gaze, exactly as they looked at God.

Qin Yu's ink eyes were as bright as stars, Bai Yingying's heart trembled, and Fatty Wang pinched his thighs purple.

but……

Jiang Nan, as the person involved, had a calm face, and only snarled at Xie Hongwei on the podium, "Teacher, these questions are too simple, it's not difficult at all!"

"or……"

"Are you trying something more difficult?"

"..."
