If an integer a is divided by an integer B, B is not zero, and the quotient of the division is exactly () and there is no remainder. Let's say that a is () of B and B is ()

whole
multiple
Factor (or divisor)

Solve the equation x 7 / 4 + 4 = 5 / 3
fast

4 out of 7 plus 4 = 3 out of 5
x = ( 3/5 -4 ) ÷ 4/7
= - 17 / 5 x 7/4
=- 119 out of 20

In terms of scientific creation, we can cite the age at which some famous figures in history made achievements: Galileo discovered the pendulum principle at the age of 17

The best age for scientific creation is youth

Can you talk about Galileo's "pendulum principle"

In short, when the pendulum is not disturbed by the external force, the state it presents is static. Once it is affected by the external force, the pendulum will start to shake left and right. The greater the external force is, the stronger the force will be under the influence of inertia. With the influence of gravity, the pendulum will swing more slowly, and finally return to the origin, showing the original static state

When did Galileo discover the pendulum principle?

1583, when he was 19

The students in the class studied the text "experiment on the Leaning Tower" together and discussed the pendulum law discovered by Galileo warmly
Some students say that his discovery is accidental; some say that it is the inevitable result of Galileo's knowledge reserve to a certain extent; some say that when science and technology develop to this point, Galileo does not discover the law of pendulum, other scientists will also discover it. So, how do you know this?

He can find that he seized the opportunity, and he was fully prepared for the opportunity before he met it, that is, his accumulated knowledge and experience, and his patience until the end. This is why he succeeded
If it's an accident, then this opportunity will give you. Can you stick to this rule? If it's you, maybe you will ask if there is any rule. But you have no experience, you don't have the accumulation of knowledge, and your research department will come out. Therefore, even if you are given this opportunity, you will not succeed. What do you say?
Therefore, success is not accidental, but opportunity is accidental. Galileo's success condition is opportunity plus his own ability
Please give me points, thank you

What is the unit of each symbol in L / G under the root sign of Galileo's pendulum law formula t = 2pi *?

The unit of L is m, the unit of G is m / S & sup2;, so the unit of T is s

Ansai waist drum, Lesson 17, Beijing No.4 Middle School

Author: Liu Chengzhang
A group of luxuriant posterity
Behind them is a field of sorghum. They are as simple as that one
The hissing south wind stirred the sorghum leaves and their clothes
They look calm and quiet. The waist drum, which clings to one side of their body, seems to never ring
However:
Look——
One hundred and ten posterity with oblique back drums, like one hundred and ten stones constantly hit by strong earthquakes, dance wildly in front of you. Like a sudden rain, it is a rapid drum; like a whirlwind, it is a flying tassel; like a random frog, it is a jumping footstep; like a spark, it is a flashing pupil; like a fighting tiger, it is a strong posture, What a magnificent, bold and fiery dance burst out - Ansai waist drum!
The waist drum makes the cold air become hot and dry, the quiet sunshine splash, and the sleepy world become excited
What an Ansai waist drum!
The heavy sound of a hundred waist drums collided on the cliff with wild jujube trees. The cliff suddenly turned into a cowhide drum face
The heavy sound of a hundred waist drums collided with the hearts of the audience who had left everything behind. The hearts of the audience suddenly turned into a cowhide drum face, which was also rumbling, rumbling, rumbling
What an Ansai waist drum!
The arms, legs and whole body of the posterity are beating powerfully, rapidly and on the ground. It shakes you, burns you and threatens you. It makes you feel the existence, activity and strength of life more clearly than ever before. It makes you marvel at the body wrapped by the farmer's clothes, the body digesting the old pumpkin, It can release such magnificent energy!
Where the Loess Plateau, you gave birth to the vitality of these young. Only you, can bear such a thrilling fight!
What a Loess Plateau! What an Ansai waist drum!
Every dance is full of power. Every dance is loud. Every dance is the change of light and shadow. Every dance makes people shudder. In the strong enjoyment of art, it is amazing
What a happy and imaginative Ansai waist drum!
Pain and joy, life and dream, getting rid of and pursuing, are interwoven, rotated, condensed and sublimated in this dance and drum!
People, become a vast; sound, become a vast
When it came to an abrupt end, the world was so strangely silent that people felt very strange to her
It's like coming to another planet
Ear is a distant crow

Read the passage
The arms, legs and whole body of the posterity are beating powerfully, rapidly, and in a big way. It shakes you, burns you and threatens you. It makes you feel the existence, activity and strength of life more clearly than ever before. It makes you wonder at the body wrapped in the farmer's clothes, the body digesting the old pumpkin with red bean horn, It can release such magnificent energy!
On the Loess Plateau, you have given birth to these vigorous young people, and only you can bear such a thrilling beating!
The watery Jiangnan is fragile glass. You can't beat such waist drum there
In addition to the Loess Plateau, where there is such a thick soil!
What a Loess Plateau! What an Ansai waist drum!
Every dance is full of power. Every dance is loud. Every dance is the change of light and shadow. Every dance makes people shudder. In the strong artistic enjoyment, it is amazing
What a happy and imaginative Ansai waist drum!
The more I beat, the more intense! The body became a heavy and flying thought!
There is no secret in my mind!
Pain and joy, life and dream, getting rid of and pursuing, are all intertwined in this dance and drum, spinning, condensing, rushing, radiating, flying, sublimating, people, and sound, and so on
When it came to an abrupt end, the world was so strangely silent that people felt very strange to her
It's like coming to another planet
Ear is a distant crow
1. What's the difference between using and not using the word "unexpectedly"?
2. How to read the sentence "interweave, rotate, condense, rush, radiate, soar, sublimate" and explain the reason
There are no exercises after class. Please spend some brain cells to help me think about it

If you don't use it, you won't be able to write the author's mood. "Interweaving" & nbsp; & nbsp; & nbsp; & nbsp; rotating "& nbsp; & nbsp; & nbsp; cohering" & nbsp; & nbsp; & nbsp; & nbsp; rushing "& nbsp; & nbsp; & nbsp; radiating" & nbsp; & nbsp; & nbsp
