Hello everyone! Hello An Nhien, Man Chau, Ngoc Hai, Cam Tien, Le Dai Phong, Nguyen Thu Hello everyone! Hello Cong Thanh, Tien Dat, Huyen Trang, Vy Truong I'm looking for something interesting There's nothing interesting Hello Thao Van, Huong Anh, Quang Bach Can you send me a car to go back to Tuong? I think Flank has been replaced Flank has only 2 minutes Hello Ha Duy Kien, Tran Thanh Truc I'm a bit humble, but I'm practicing This is the first day of Flank I think it's not 2 minutes It's 2 minutes already I can do 100 push-ups I can do 50-60 push-ups But Flank just started practicing today It's not 2 minutes yet According to my guess, it's not 2 minutes yet I counted, it's not 2 minutes yet That's it! Hello Duy Tien It's 2 minutes already It's the right form I'm a martial artist This is my chat channel I can do 50-60 push-ups I can do 100 push-ups But Flank just started practicing I can do 100 push-ups But I've never done 100 push-ups I think I can do 60-70 push-ups I can do 60-70 push-ups But I've never done 100 push-ups I think I can do 60-70 push-ups But I've never done 100 push-ups Hello Tran Manh Giap Why are you log-friend? I'm log-friend Do you eat beef or squid for lunch? I'll eat both I'll cook both beef and squid for lunch I'll go to the kitchen after this live stream I'm so strong You can do it You are strong Do you remember your Taekwondo? Ok Let's start Ok You are good at cooking You are good at washing dishes I was raised by 7 friends, my parents were strict, so I was born in a family of 7, so I have a lot of talents. I'm the best at drawing. Ok, I'm going to teach now. Let's start. The goal of this week is to get the root of the first column and the second column. Today, I will have 20 questions. There are only 19 or 20 questions. Actually, only 20 questions are difficult. If you have a hard time watching to the end with me, you will see that the 20 questions are very good and very fake. And if you can't stand the heat, you won't be able to see the details and the best of the 20 questions. The 20 questions are the best. Ok, let's start. The first question. A small object moves in parallel, which mass does not change in parallel? That is the root. Omega is a number, it does not change in parallel. So what is our first question? Our first question is D, right? The first question is D. Is it reasonable? The first question is D. The second question. A small object is moving gradually, which mass is decreasing over time? That is the function. In the motion of a small object, the function and the frequency decrease over time. And the frequency, or momentum, or momentum changes over time. Do you understand? The second question is D. Right? Oh, almost 500 people have watched it. Can you give me a name to share? 500 people have watched it. Oh, that's fun. This is fun. Oh, 500 people have watched it. Thank you. The third question. An object has a magnitude equation of x minus 5, 4πt. What is the frequency and initial phase of the motion? The frequency is 5, right? And the initial phase, I will put the minus sign inside, so it is π, right? That's it. So our answer is A. The third question must be A. Do you understand? The minus sign outside the column, I put it inside the column, so it will be π. So our initial phase is π. The initial phase, the object is in the parallel. The third question is A. The fourth question. The pulling force acts on an object. The pulling force always has a direction to the equilibrium position. The pulling force is like the acceleration. It has a direction to the equilibrium position. And its magnitude is proportional to the magnitude of the magnitude. Do you understand? The fourth question is C. Do you understand? Remember. The pulling force acts on an object. The pulling force is like the acceleration. The pulling force always has a direction to the equilibrium position. And its magnitude is proportional to the magnitude of the magnitude. You have to pay attention to the two words, magnitude. You can't miss any word, magnitude. Do you understand? Our fourth question is C. Do you understand? What is our fifth question? What is the fifth question? Please comment on the fifth question. The pulling force acts on an object. You are wrong about the fifth question. This morning, there were about 400 people who took the exam. You are wrong about the fifth question. You read it wrong. What do you want to calculate? You want to calculate the pulling force, right? The pulling force is equal to the magnitude of the magnitude of the magnitude. But unfortunately, you don't calculate the magnitude of the magnitude. The direct formula of the pulling force is the magnitude of the magnitude. But you also know that the pulling force is equal to the magnitude of the magnitude. So the magnitude of the pulling force is equal to the magnitude of the magnitude. So the fifth question is C. Do you understand? What is the sixth question? When do the two pulling forces intersect? This question is part of the total pulling force. When do the two pulling forces intersect? The magnitude of the pulling force is the magnitude of the magnitude. When do the two pulling forces intersect? The magnitude of the pulling force is the magnitude of the magnitude. When do the two pulling forces intersect? The magnitude of the pulling force is the magnitude of the magnitude. So what is the magnitude of the magnitude? 2n-1 is the magnitude. The sixth question is D. The seventh question is C. The eighth question is D. The ninth question is C. The tenth question is D. The eleventh question is C. The twelfth question is D. The twelfth question is C. The twelfth question is D. The twelfth question is C. The twelfth question is D. The twelfth question is C. The twelfth question is D. The twelfth question is C. The twelfth question is D. The twelfth question is C.

The twelfth question is C. The twelfth question is D. The twelfth question is C. The twelfth question is D. The twelfth question is C. The twelfth question is D. The time to tick two numbers must rotate an angle of 2 degrees. So, how many degrees does it rotate? In 0.5 seconds, how many periods? 1 over 4 periods. 1 over 4 periods is 90 degrees. So, what is the degree of rotation? 45 degrees. Because 90 is twice the degree of rotation. The time to tick two numbers is twice the degree of rotation. 45 degrees. So, you have to put it on the scale. 4 plus 6 minus 2 times 4 times 6. 4.5. Note that you have to put it on the degree of rotation. The degree of rotation is 4.249. It is close to the answer of B. The degree of rotation is 4.249. It is close to the answer of B. Those who put it on the radius, it is close to the answer of C. You will see that the answer is wrong. Put it on the degree of rotation. 18 is B. Now, let's go to the last 2 questions. Question 19 and 20. These are 2 difficult questions. Actually, question 20 is a difficult question. But question 19 is still an easy question. So, today you have a headache or something? Obviously, the answer is B. But why did you call the ticket D? That's right. That's normal. Everyone has to be stupid at least 10 times in their life. Not just once. Here's what question 19 says. People say that a thing has a momentum according to time as shown on the side. At the time 1 second, the force of the spring, who is wrong, the force of recovery, the force of recovery,
