The questions at the front of the physics monthly examination paper were all within the scope of the examination. In Qin Ke's eyes, they were not difficult. He finished them in less than ten minutes like chopping melons and vegetables.

But the last one was obviously an extra question prepared for himself, and he had to study his own extra paper questions, which gave Qin Ke a little headache.

He rubbed his temples. What kind of weird question is this? Are you sure it's a physics question?

"Additional question: One day in October, Xia time, a bear fell into a trap specially set by a hunter. Now we know that the pit is 19.6124 meters deep and the fall time is exactly 2 seconds. Please answer which continent the hunter is most likely to be from.

Human? What color is a bear?"

Qin Ke was complaining in his heart. How can a hunter dig such a deep pit? If a bear falls and is almost dead, how can you, the hunter, pull up the heavy bear? If it is all done manually by one person, how can this work be done by one person?

The total amount is probably more than the value of a bear!

But obviously the question did not allow him to solve these embarrassing questions, but asked about the origin of the hunter and the color of the bear.

The physics exam is actually linked to geography and biology?

Qin Ke bit his pen and thought deeply.

He can easily calculate g=9.8062 based on h=1/2gt^2 using mental arithmetic. This is obviously not 9.832 at the North Pole, nor 9.780 at the equator. Polar bears can be excluded, and it can only be in the middle area of ​​the northern and southern hemispheres.

.

From g=9.7803(1 0.00sin2ψ-0.000005sin22ψ) m/s (ψ is the latitude)

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

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

It is impossible to dig such a deep hole to deal with small bears, so the chances of spectacled bears and sun bears are low.

Only brown bears and black bears remain.

According to the biological distribution map, brown bears mainly inhabit coniferous forests in the cold temperate zone, that is, between 50° and 65° north latitude, which is inconsistent with the calculated 45°, and the surface of the cold temperate zone is too hard to dig deep pits.

Black bears are more widely distributed, inhabiting forest environments ranging from low-altitude tropical rainforests to subtropical evergreen broad-leaved forests, river valley shrublands, temperate deciduous broad-leaved forests, coniferous forests, and mountain cold temperate dark coniferous forests.

, and they also have the habit of vertical migration. In summer, their main habitat is in higher mountain forests, but before winter, they will gradually move from the highlands to river valleys at lower altitudes.

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

What's more, the trap can be dug to 19.6124 meters. The soil must be softer impact parent material to be easy to dig, and the river valley terrain is the most suitable for the conditions.

Moreover, black bears are also called blind bears. They have poor eyesight and are more likely to be caught in traps.

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

Based on the above analysis, the highest probability of this bear should be a black bear.

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

The Xia State has classified the black bear as a second-level protected animal and strictly prohibits illegal hunting, so this hunting can only occur in North America.

What's more, American black bears are widely distributed in the mountains and forests of North America. They are the most abundant bear species in the world, and the probability of their hunters being North Americans is highest.

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

Damn, this is the first time he has done so awkwardly on a physics question.

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

Qin Ke secretly glanced at Ning Qingyun, who was half a meter away, and saw that Ning Qingyun was taking a normal test paper without the additional test paper.

He couldn't help but wonder, does physics also need to be selected in advance? Isn't the physics competition only held in the next semester?

Unfortunately, the same thing happened to Qin Ke in the chemistry exam that followed. Even the biology exam 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. Although it took some effort, he was able to solve all the additional questions in chemistry and biology.

After the monthly exam ended one afternoon, Qin Ke was so full that he vomited out of nowhere.

Did I make a mistake? I wasted my exam sleeping time that could earn me three times the God of Study experience points!

If you don’t give me extra points but you still deduct points, I will file a complaint!

On Wednesday morning, as the 150-point comprehensive liberal arts exam was handed in, the unexpected monthly exam finally came to an end.

Qin Ke estimated that he would probably be in the top five in the class, but it was hard to say what grade he was in. The questions this time were not as difficult as in the midterm exam, and the average grade score might be higher.

But after taking the exam, Qin Ke put the matter behind him. Anyway, the results were no longer up to him. After lunch, Qin Ke finally received the express text message. He greeted Li Xiong and several other golfers at noon.

I stopped playing basketball because I had something to do, and then ran to the mailroom to retrieve a package.

Inside was of course the top-of-the-line fruit notebook that he had longed for and finally had it shipped to him.

Qin Ke originally wanted to take it back to the dormitory, but after thinking about it, he thought it was too arrogant and would embarrass Wei Wenping if it spread, so he took it to the old art room in Building B, which is now the Orsay Special Training Room.

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

To his surprise, the door of the old art room was actually open, and Ning Qingyun was sitting on the original window seat reading quietly. This gave Qin Ke a sense of surprise and happiness as if he had met by chance.

However, he quickly put away his joyful smile and just asked in a normal tone: "Hey, why are you here, school committee member?"

Qin Ke asked while holding the computer packaging box inside, and naturally sat back down on the seat next to Ning Qingyun.

"I have been studying here at noon every day recently." Ning Qingyun was also used to it. She looked over curiously: "What are you holding?"

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

This chapter is not over yet, please click on the next page to continue reading! Ning Qingyun recognized it as the latest model of Fruit Notebook, which is close to 100 yuan and not cheap - why would she know? Because her grandma bought her one before school started

It's exactly the same, but she left it at home and didn't take it back to school.

"Why did you buy a fruit laptop? If the teacher finds out, it will be confiscated!"

"It's not for my own use. Didn't I get a scholarship recently? I just bought a laptop for my little sister as a birthday gift. Tomorrow is her thirteenth birthday."

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

She noticed that Qin Ke usually wore school uniforms. Even when he didn't need to wear school uniforms on weekends, he only wore ordinary cheap jackets and jeans. Who would have thought that this guy would be willing to buy such an expensive gift for his little sister?

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

"It's almost 30,000 yuan. It's not cheap. Who do you call a relative? Although that little girl is unreliable and lazy and will only rely on me all day long, I only have such a little girl. If I don't love her, who will I love?"

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 arrogant, but his gentle look when he talks about his family always makes people feel good about him.

Qin Ke connected the Fruit Notebook to the hotspot shared by his mobile phone and installed commonly used software on it, while pretending to be casual and said:

"By the way, School Committee, I just asked Teacher Wei for leave. I won't be at school from tomorrow to the morning of the day after tomorrow. I want to go back to my hometown to celebrate my little sister's birthday. What is your mobile phone number? Please 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 via mobile phone."

The reason was fair and aboveboard. Ning Qingyun hesitated for a moment and then reported her mobile phone number. Qin Ke took note of it and rang her phone.

Ning Qingyun saved it slowly. Thinking that this was the first boy's number added to her phone besides her father, grandfather and other relatives, her little face couldn't help but blush a little, and she felt inexplicably happy.

"There is also WeChat. You open the QR code and I will scan it for you." Qin Ke moved much faster than her.

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

Qin Ke went over to scan the code and added it successfully.

Yeah, I got Ning Qingyun’s contact information!
