I really just want to be a scholar

Chapter 84 What Color is the Bear?

The questions in front of the physics monthly exam papers were all within the test range, and in Qin Ke's eyes, there was no difficulty. He was like chopping melons and vegetables, and finished it in less than 10 minutes.

But the last question that was obviously prepared extra for himself and had to study himself, gave Qin Ke a bit of a headache.

He rubbed his temples on his forehead, what kind of strange question is this?Are you sure you are taking a physics question?

"Additional question: One day in October of Xiaguo time, a bear fell into a trap specially set up by hunters for it. Now we know that the pit is 19.6124 meters deep, and the falling time is exactly 2 seconds. Please answer, which continent is the hunter most likely from? Human? What color bear is a bear?"

Qin Ke couldn't stop complaining in his heart, what would the hunter use to dig such a deep hole?The bear is almost dead when it falls, how can you hunter pull up the heavy bear?If it is all done manually by one person, the workload may add up to more than the value of a bear!

But obviously the question didn't ask him to solve these annoying problems, but asked about the hunter's origin and the color of the bear.

The physics exam is actually linked with geography and biology?

Qin Ke bit his pen and pondered.

He can easily calculate g=1 based on h=2/2gt^9.8062 with mental arithmetic, which is obviously not 9.832 at the North Pole, nor 9.780 at the equator, so polar bears can be excluded, and they can only be in the middle of the northern and southern hemispheres .

由g=9.7803(1+0.0053024sinψ-0.000005sin2ψ) m/s （ψ为纬度）

The calculated latitude ψ is 45°, that is, 45° south latitude or 45° north latitude.

Qin Ke tried his best to recall, and the remaining types of bears were probably spectacled bears in the southern hemisphere, brown bears, black bears, and dark brown sun bears in the northern hemisphere.

It is impossible to deal with small bears if they dig such a deep pit, so the probability of spectacled bears and sun bears is not high.

Only brown bears and black bears remain.

According to the geographical map of biological distribution, brown bears mainly inhabit cold temperate coniferous forests, that is, between 50° and 65° north latitude, which does not match the calculated 45°, and the surface of the cold temperate zone is too hard to dig deep pits.

The distribution of black bears is wider, ranging from low-altitude tropical rainforests to subtropical evergreen broad-leaved forests, valley shrubs, temperate deciduous broad-leaved forests, coniferous forests, and mountain cold temperate dark coniferous forests. , and they also have the habit of vertical migration. The main habitat in summer is in the higher mountain forests, but before winter, they will gradually move from the highlands to the river valleys at lower altitudes.

October is just before winter, and it is very likely that the black bear fell into a trap after going down the mountain.

What's more, the trap can be dug to 19.6124 meters. The soil must be a soft impact parent material to be easy to dig. The valley terrain is the most suitable condition.

Moreover, black bears are also called blind bears, with poor eyesight and a high possibility of falling into traps.

In addition, from an economic point of view, generally bear paws and bear bile are mainly taken from black bears, which are not as aggressive as brown bears.

Combined with the above analysis, the bear with the highest probability should be a black bear.

There are two types of black bears: Asian black bears and American black bears.

And Xia Guo listed the black bear as a second-class protected animal, and illegal hunting is strictly prohibited, so this hunting can only happen in North America.

What's more, the American black bear is widely distributed in the mountains and forests of North America. It is the largest number of bears in the world, and the hunters have the highest probability of being North Americans.

Qin Ke finally finished writing and wiped the sweat from his forehead.

Sister, this is the first time he has done a physics problem so embarrassingly.

Qin Ke couldn't help but glanced at the physics teacher Xu Qingyan who was pacing back and forth on the podium, and muttered in his heart, why did Teacher Xu come up with such a problem to embarrass me?

Qin Ke sneaked a sneak peek at Ning Qingjun, who was half a meter away, and saw that Ning Qingjun did the usual test papers, without the additional papers.

He couldn't help wondering, should physics be selected in advance?Isn't the physics competition only available in the next semester?
Unfortunately, the same thing happened to Qin Ke in the next chemistry test, and even the biology test was no exception. The whole class had an extra question on his paper.

Fortunately, Qin Ke's logical thinking in science has been greatly strengthened now. Although it took a little effort, he has also done the additional questions of chemistry and biology.

After the monthly exam in the afternoon, Qin Ke was full of complaints from nowhere.

There is no mistake!I wasted my sleeping time for exams that I could earn three times the experience points of learning the gods!

If you don't give me extra points but also deduct points, I'm going to complain!

On Wednesday morning, with the handing in of the 150-point comprehensive essay exam, this unexpected monthly exam finally came to an end.

Qin Ke estimated that he would probably be able to get in the top five in the class, and the grade would be hard to say. The questions this time are not as difficult as the midterm exam, and the average score of the grade may be higher.

But after the exam, Qin Ke put this matter behind him, anyway, the results are no longer up to him.After lunch, Qin Ke finally received a text message from the courier. He, Li Xiong and other golfers said hello that they would not play golf at noon, and then ran to the mail room to retrieve a package.

Inside is the top-end fruit notebook that was delivered with great difficulty, of course he wanted it in his heart.

Qin Ke originally wanted to take it back to the dormitory, but after thinking about it, he felt that it was too public and would embarrass Wei Wenping if it spread, so he took it to the old art room in Building B and the current Orsay special training room.

Anyway, only he and Ning Qingyun had the key there, so it was very safe.

To his surprise, the door of the old art room was actually open, and Ning Qingyun was sitting in the seat by the window, reading a book quietly, which gave Qin Ke the surprise and joy of meeting by chance.

But he quickly put away his joyful smile, and just asked in an ordinary tone: "Hey, why are you here?"

Qin Ke asked while hugging the computer box inside, and of course sat back on the seat next to Ning Qingyun.

"I've been studying here at noon every day recently." Ning Qingyun is also used to it, and she looked over curiously: "What are you holding?"

"Fruit laptop." Qin Ke opened the box and took out the computer inside.

Ning Qingyun recognized that it was the latest fruit notebook top-end, which was close to 27000 yuan, which was not cheap—why did she know?Because her grandma bought her exactly the same one before school started, but she left it at home and didn't bring it back to school.

"What are you buying the fruit laptop for? If the teacher finds out, it will be confiscated!"

"I don't use it myself. Didn't I get a scholarship recently, and I happened to buy a laptop for my little sister as a birthday present. Tomorrow is her 13 years old birthday."

Ning Qingjun looked at the brand-new laptop that Qin Ke took out, and couldn't help feeling: "You are so kind to your sister. Isn't this laptop cheap?"

She noticed that Qin Ke usually wears school uniforms, even on weekends when he doesn't need to wear school uniforms, it's just an ordinary cheap jacket and jeans, who would have thought that this guy would be willing to buy such an expensive gift for his little sister?

This guy dislikes his sister in his mouth, but he is a good brother in his heart.

"It's almost [-] oceans, it's not cheap. Who is a relative? Although that little girl is unreliable and lazy, and only depends on me all day long, but I only have such a little girl, and I don't love her or anyone else."

Noticing the pain in Qin Ke's eyes when he talked about his little sister, Ning Qingyun couldn't help but look away.

This guy is usually ruffian, but his gentle look when he mentioned his family can't help but make people feel good.

Qin Ke connected the fruit notebook to the hotspot shared by his mobile phone and installed common software on it, while pretending to say casually:

"By the way, school committee, I asked Teacher Wei for leave just now. I will not be at school from tomorrow to the morning of the day after tomorrow. I have to go back to my hometown to celebrate my little sister's birthday. What is your mobile phone number? Add WeChat and QQ by the way. Just in case If I have any questions about English during my leave, I can always ask you through my mobile phone.”

This reason was aboveboard, Ning Qingyun hesitated for a moment, and still reported her mobile phone number, Qin Ke wrote it down and rang her mobile phone.

Ning Qingyun saved it slowly, thinking that this was the first male number added to her mobile phone besides her father, grandfather and other relatives, her little face turned red, and she felt inexplicably happy.

"And WeChat, you open the QR code, and I'll scan it for you." Qin Ke moved much faster than her.

Under his urging, Ning Qingyun opened the WeChat QR code.

Qin Ke leaned over to scan the QR code and added it smoothly.

Yay, Ning Qingyun's contact information is in hand!
