Turn on the live stream. Go, go. Hello, everyone. I'm Minh Tri. I'm Hoang Lich. I'm Thon Nu. I'm Hao Huyen. I'm Thinh Bui. I'm An Duy Vu. I'm Duy Phong. Many people woke up late this morning. I'm Anh Tuyet. I'm Van Tinh. I'm Van Tam. I'm Duong Huu, Ngoc Duong. I'm Minh Chau. I'm Thanh Phuong. This morning, I woke up late. I have a feeling that many people will forget to wake up and go to school today. It seems that the weather makes us sleepy. Hello, Quoc Thang. Hello, Minh Duc. Hello, Ho Minh Duc. I woke up late. It seems that the weather makes us sleepy and can't wake up. Hello, Bac Tho. Hello, Thinh Bui. Hello, Bao Han. Hello, Van Thanh Duc. This morning, the weather makes us hard to wake up. It seems that it's hard to wake up today. Let's go to school. I have work at 5.50 am. I have work at 5.40 am. Hello, Le Khanh Hien. I've been talking all week. This is the 6th live stream in this week. This is the 4th live stream in this week. I've been live-streaming for the 2nd, 3rd, 4th, 5th. It's been 4 weeks. Tomorrow, I won't be live-streaming outside of Fanpage. I'll be live-streaming in Tieng Anh. Okay. Hello, P Quyen, Thanh Khai, Khanh Hien. Tomorrow, I'll be live-streaming in Tieng Anh. The number of viewers is decreasing. That's why I didn't upload any files this morning. I've been live-streaming for the audience because I've been working on this book. There are a lot of exercises in this book. I've been working on it day and night. That's why I didn't upload any files. I've been working on it day and night. I've been working on it day and night.

Question 6 The R-L-C connection is anti-shaking. When C increases to a very large value, what happens to U-R? U-R also belongs to the group of 6 large atoms. U-R changes to C. Then C goes up. Our connection is anti-shaking. Anti-shaking is on the left hand side. When C increases, C goes up. Then C goes down. When C increases, C goes down. When C decreases, C decreases. When C increases, C decreases. When C decreases, C decreases. When C increases, C decreases. When C decreases, C decreases. When C increases, C decreases. Question 6 is about R-L-C connection. But a lot of you will miss the 7th question. Our connection is R-C. So our potential is U-R followed by C. Our connection is R-C. The negative part of the connection is losing the positive part. The potential is only half. It is losing the positive part. How can we know? It is increasing like this It can't go down anymore. It has lost half of its sensitivity. Because half of our body is anti-vibration and the other half is anti-sensitivity. So if we increase C from 0 to extremely large, our UER will always increase. The answer A is the correct answer. This is a difficult question. We only have R and C. Let's continue with question 8. We have R and C. R and C have both vibration and sensitivity. When we increase L from 0 to extremely large, what happens to the anti-vibration? Let's draw a diagram. Y follows L. The diagram is quite good. Up and down here. Increase L from 0 to extremely large. Y increases and then decreases. Z must decrease and then increase. Z must be opposite to Y. Y increases and then decreases. Z must decrease and then increase. These two are opposite to each other. Let's continue with question 9. What is the answer for question 9? We have R and C. R and C have both vibration and sensitivity. When we decrease L from 0 to extremely large, what happens to the anti-vibration? Let's draw a diagram. Y follows L. Increase L from 0 to extremely large. Z must decrease and then increase. Y increases and then decreases. Z must be opposite to Y. When we decrease L from 0 to extremely large, what happens to the anti-vibration? Y increases and then decreases. Z must be opposite to Z. Y increases and then decreases. Z must be opposite to Z. So the answer for question 9 is C. Is that correct? Let's continue with question 10. R and C have both vibration and sensitivity. When we increase L from 0 to extremely large, what happens to the anti-vibration? Y follows L. Z must be opposite to Z. When we increase L from 0 to extremely large, what happens to the anti-vibration? Anti-vibration is on this side. When we increase L from 0 to extremely large, Z must be opposite to Z. So the answer for question 10 is A. Is that correct? So the answer for question 10 is A.
