v2 Chapter 100： Physics in the mist
Yongjiang Yonglai also hurried and hurried.
Qi Jiang Weiguo did not want to make any evaluation on this.
三 His third brother is the same, what the son wants to eat, as long as it is not outrageous, if it is too outrageous, it will be noisy.
When Jiang Jiang was a kid, he did n’t know who to listen to. He had to eat boiled cabbage. After two days, he was severely beaten by Jiang Weiguo, and he was punished by cutting onions and peppers for two days.
Weijiang Weiguo is hanging the soup.
He has been busy since the early morning, and slaughtered one of the fattest old hens raised by Grandma Jiang, and even processed other ingredients by the side of this pot of broth.
Jiang Feng ate another small piece and told others to come and eat it. The two sisters Jiang Jianqing and Jiang Yanlian ran the fastest. One dug two spoons and it was quite good. After eating, what was left? A quarter was left to Jiang Jianguo's five brothers.
"Grandpa, this is delicious, can you make this tomorrow!" Jiang Yanqing's eyes brightened.
"You and I will learn how to cook for a few years, but you will be able to do it yourself in a few years." Jiang Wei National Road.
Qiujiang squeaked when he cleared.
The grandsons and granddaughters of Qiujiang Weiguo belonged to her. She cut vegetables for the first time and did not learn without squeezing a few drops of blood.
I have to lose because she is Jiang Weiguo's granddaughter, not her daughter, or she must hang up and fight.
"Okay, just go out and don't bother in the kitchen." The old man started to blast.
A group of obnoxious grandchildren was kicked out.
Everyone was trying to find their own moms in each room. Jiang Yanqing and Jiang Yanlian stopped their four elder brothers and looked at them pitifully.
"Our winter vacation homework will not be done." The two sisters said in unison.
Jiang Zaide fought a chill, and the first one was ready to start: "I can't. I have worked all the junior high school things. I forgot about it. Look for your brother. He was in the top 20 of the city's college entrance examination for more than 660. Look for him! He Good grade! I have to go back to the house to change the plan. "
"I can't do it either. I have a college entrance examination of 660 and my middle school entrance exam is only 600. My junior high school is not good. I have forgotten all the junior high school and I forgot about it. Look for you Ran brother!" .
Jiang Ran immediately panicked and hurriedly dumped the pot: "I can't do it either. I didn't get 660 in the college entrance exam! I want to teach you not to miss your children or not to lay the foundation for you Will high school develop in the future? Besides, I have forgotten all about studying finance. I ca n’t. I want to find your fourth brother. He studies physics and ca n’t distinguish between mathematics and science. He can definitely do it! , Better than me! "
Minjiang Feng :?
"Isn't that Qing Qing bad in physics? Brother Xiaofeng, who specializes in physics, asks him, it's all right!" Jiang Ran slipped after exquisitely shaking the pot.
"Brother." Jiang Yanqing and Jiang Yanlian looked at Jiang Feng together.
Min Jiangfeng: ...
Don't sell cute, you are almost over me.
However, Jiang Yanqing and Jiang Yanlian were in their third year of study, and their study was indeed critical. In June, they had to take the entrance examination. Since they are interested in studying, Jiang Feng naturally cannot refuse to teach.
She entered the room with them, and Jiang Feng saw a familiar book on the table.
The blue physics "3 years simulation of 5 years of high school entrance examination", shining white and yellow characters highlight its unshakable status in teaching materials for so many years.
"Brother, rest assured, it is not difficult, the problem of the second year." Jiang Yanqing comforted and opened the book.
Qiu Jiangfeng was relieved at the first hearing. The physics of the second grade was just getting started. It was very simple.
Then look intently.
2. As shown in the figure, place a piece of ice in a beaker filled with water. The lower surface of the ice cube is in contact with the bottom of the cup, and the water surface is exactly the same as the mouth of the cup. Regarding whether there is water overflow when the ice melts, the following judgment is correct. Yes ()
A. When the bottom surface of the ice cube faces pressure on the bottom of the cup, the water will definitely overflow after the ice melts
B. When the bottom surface of the ice cube is under pressure against the bottom of the cup, the water must not overflow after the ice has melted
C. Whether or not the bottom surface of the ice cube is under pressure against the bottom of the cup. Water will overflow when the ice melts
D. Whether or not the bottom surface of the ice cube is under pressure against the bottom of the cup. Water will not overflow after the ice melts
Minjiang Feng :?
Is this picture a bit abstract?
Forget it, look at the next question.
8. As shown in Figure A, under the action of a horizontal leftward pulling force F1 with a size of 30N, an object with a weight of 80N makes a straight linear motion at a speed of 0.4m / s on the horizontal plane. Then use the pulley group shown in Figure B to pull the object. Under the action of the horizontal pulling force F2, the object moved linearly at a uniform speed of 0.5m on the same horizontal plane at the same speed in the horizontal direction. The friction of the rope is not taken into account). The following statement is correct ()
A. The friction between the object and the horizontal plane is 15N
B. The power of the pull force F2 is 36W
C. The pull force F2 is 90N
D. The work done by pulling force F2 is 15J
Min Jiangfeng: Hey, this question will.
Qi Jiangfeng started speaking confidently.
five minutes later--
Qiujiang Qing and Jiang Yanlian looked at Jiang Feng with a look of confusion.
Min Jiangfeng: ...
He just didn't understand enough?
Don't understand this?
"Forget it, brother, let's talk about it." Jiang Yanlian tried to help Jiang Feng resolve the embarrassment.
Min Jiangfeng: ...
咳 "Ah, um, ah." Jiang Feng tried to haha to demonstrate his embarrassment. "This kind of question is not taken in the middle school entrance examination."
Qijiang Feng received two skeptical eyes.
"No, brother, we have this kind of question in the middle school entrance exam simulation paper." Jiang Yanqing didn't believe it.
"Ah, I didn't take the exam in that year!" Jiang Feng could not remember what he took in the exam in that year. He wouldn't just fail the exam.
"Your brother and I have passed the middle school entrance examination for several years. Maybe it has been reformed now. Change it, math, how about math?" Jiang Feng said haha.
Minjiang Qianlian came up with a green five-three math.
The lush green color made Jiang Feng very moved.
Junior high school mathematics, he can!
Not only will he, he is better at math than physics, and he helped Chen Xiuxiu make up math every day in high school!
I tutored my two cousins for half a morning of mathematics, and Jiang Feng deeply felt the suffering of the teachers in the middle school. The feeling is that you do n’t know how to do this, you do n’t know how to do this, how did you read the third grade, I just talked about how you ca n’t do it again.
The tutoring work really had to be far away and close attack, and getting closer to the teacher really couldn't help but want to take books to pump them.
Qi Jiangfeng thought for a while that they had two people, and the twins had a tacit understanding. Together, they really didn't necessarily win, they had to put down the book in their hands.
Forget it, I wo n’t be stung for a while, take a step back and avoid going to the hospital ~ www.novelhall.com ~ Eat dumplings and yesterday ’s leftovers, everyone knows that tomorrow will have the most hearty meal of the year, and do n’t care Eat a little less today and hungry tomorrow.
Eat one bite less today and you can eat one more bite tomorrow, rounding up makes a bite.
Qijiang Feng held the bowl beside Jiang Zaide and complained with his brother in the lobby: "The foundations of Qiongqing and Qilian are also too bad. Should n’t education in city A be better than city Z?"
"The two of them have always been used to sneaking around." Jiang Zaide sipped a dumpling. "Originally, we are hanging sandbags. Hanging for a few days and then lazily playing are not enough. The knives also cut everything, and said after cutting for two hours. My hands are sore, I cut my hands and quit. "
"The two of them, Yan Lian is a little better. She Qing cut her hand once and quarreled and did not learn. Thanks to their young age, grandpa was much better-tempered than before. The call is up. They don't have the hardships we had when we were cooking. They know how good reading is. "
Minjiang Feng :? ? ?
I looked surprised at Jiang Feng, and Jiang Zaide responded: "Oh, yes, I forgot, our brothers are the most honest of you, and do n’t cry when you get to them. You can continue to practice with a bag of gauze."
"Grandpa didn't care if he cried." Jiang Feng said he didn't cry.
"Whether you continue to cry, as long as you cry long enough, Grandpa will not let you practice." Jiang Zaide said.
Minjiang Feng :? ? ?
There is still this operation.
"Hey, Xiaofeng, I didn't say you, our brothers are the most honest of you." Jiang Zai German has a long way to speak.
Min Jiangfeng: ...
Oh.
We honestly did something wrong.
Honest people are lying too intermediate!
Qi Jiang Weiguo did not want to make any evaluation on this.
