Why is the Universiade weightlifting group B competition not broadcast live

In fact, it's all the same, assuming that there are 20 people who sign up for weightlifting, the top 10 with good registration results are in group A, and the last 10 are in group B. The specific number of people is said casually, and this is roughly what it means, so the level of the players in Group B is generally lower, and Zhou Jun is put in Group B because he is afraid that he will be nervous in Group A. The snatch is very technical, and the movement deformation cannot be resisted.

a. When a weightlifter lifts a barbell, the pressure on the ground is equal to the sum of his gravity and the gravity of the barbell, so it becomes larger than when he does not lift the barbell, so this option is correct;

b. The shot put will eventually fall back to the ground, mainly because the shot put is affected by gravity, so this option is incorrect;

c. When swimming, stroke backwards with your hands and feet, give the water a backward force, the effect of the force between objects is mutual, and the water will give the hands and feet a forward force, so this option is correct;

d. When shooting and aiming, the eye, the front sight, and the bull's-eye are "three points into a line", and the principle of linear propagation of light is applied, so this option is correct

Therefore, choose B

What can I do if my strength is not good?!

Hehe, it's a lottery.

It's best to be specific to each thank you

When the number of participants is large, they will be divided into two groups according to the results. Those with high scores were placed in Group A, and those with low scores were placed in Group B. So yesterday, Zhou Jun was placed in Group B, which is unique in the history of Chinese women's weightlifting.

According to the results of the preliminary round, the good results will be placed in Group A, and the poor results will be placed in Group B.

Of course, it's all together.

Groups A and B of Olympic weightlifting are divided according to the athletes' registration results. Athletes in Group A have high results and Group B have low results. The final medal will be determined by the highest score of the players in Group A and B.

Due to the generally high performance of Chinese contestants, they are all competing in Group A. Normally, the medalists are from Group A. As a result, we see only Group A matches on television.

Men's weightlifting unfortunately lost a gold medal today.

B is two, do you understand?

On August 5, Beijing time, the 2012 London Olympic Games women's weightlifting above 75 kg group A finals kicked off at the London Convention and Exhibition Center. China's Zhou Lulu won the championship with a snatch of 146kg, a clean and jerk of 187kg, and a total of 333kg, and her total score also broke the world record.

Isn't it different from international standards?
