What is the relationship between kg and kgs~ General unit is kg, but some write is kgs ~ what is the relationship between the title ~ write which is correct~` For example, 1230 kg can be written as 1230 kgs But if a table has a lot of data, can you write kgs on the top of the table? Table is sent to Japan ~ data is not fixed ~ there are many~ Do you write kg or kgs

Kg is a kilogram, odd
Kgs is kilogram, plural form
Both expressions are OK. Let's see whether the numbers in front are single or multiple

What's the difference between kgs and kg?
Is it plural to add an s after it? A kilogram is represented by 1kg, and those of two or more kilograms are represented by 2kgs and. Kgs?

You're right. It means plural
In general, kgs is used in international trade, because few goods are less than 1kg
Kgs and kg are both units of quantity. They have the same meaning, just like PC and PCs, CTN and CTNS. The difference is the difference between singular and plural

What is the unit of kgs / a
It's from the Hall effect experiment

1Kgs = 0.1t, i.e. kgs is the unit of magnetic field intensity and a is the unit of current, then kgs / A is the unit of magnetic field divided by current

What's the difference between mass and weight
So, what we usually say, for example, to weigh an object, we can say weight or mass. Do they have the same meaning?

If I ask you what the weight of something is, you will say that it is XX Jin or XX kg. Jin and kg are mass units. It can be seen that the weight we usually say is close to the mass in physics. But there is also a word "heavy" in this word, which implies that when we use this word, we consciously or unconsciously default that the weight is related to gravity, This is different from the meaning of mass, because the mass of the same object has nothing to do with gravity. No matter on the earth, the moon or other planets, the mass of the object will not change, but the gravity it receives. It can be seen that "weight" is just a popular term with vague meaning, and its scope of application is only non scientific occasions, Gravity is gravity, don't say weight, lest you will be deducted points^_^

When x takes what value, the equation 3 (X-2) = kx-8, 1 has a positive solution, 2 has a negative solution. 3 has no solution, the solution method

3(x-2)=kx-8
（k-3)x=2
K = 3, no solution
k≠3,x=2/(k-3)
1.x>0
k>3
2.x

Given two points a and B on the number axis, the distance between a and B is 1, and the distance between a and origin o is 3, then what is the sum of the distances between B and origin o?

A may be + - 3, B may be + - 2 + - 4, then the sum of the distances between all B and the origin is 12

The average age of Xiao Chen, Xiao Lin and Xiao Wang this year is 16 years old. None of them is younger than 13 years old, and none of them are the same age. So the oldest of them is () years old. Is the oldest 18 years old?

16×3 - 13 - 14
= 48 - 27
=21 years old
The average age of Xiao Chen, Xiao Lin and Xiao Wang this year is 16 years old. None of them is younger than 13 years old, and none of them is the same age. So the oldest of them is (21) years old

Xiao Mao set up a program in the computer to input the rational number x and the symbol *, and then input the rational number y. The computer operated through the set operation mode x * y = x + YX, and then output the result. (1) after Xiao Ming input 3 * 7, what is the output result of the computer? (2) When Xiaoxiao enters the data to run the program, the screen shows "can't run". Please guess how much data Xiaoxiao may input?

(1) According to the meaning of the question: 3 * 7 = 3 + 73 = 513; (2) according to the meaning of the question: Xiaoxiao, the input data may be 0 * 5

2X - square of bracket 2x - (- 5x + 1) bracket

2X - [the square of 2x - (- 5x + 1)]
=2x-(2x²+5x-1)
=2x-2x²-5x+1
=-2x²-3x+1

The sum of daily average passenger volume of ground bus and rail transit in a city is 16.96 million person times, which is 4.5% of that of rail transit
How many times less than 690000 person times? During this period, what are the average daily passenger volume of ground transportation and rail transportation

A: the average daily passenger volume of ground bus is x 10000 person times, and that of rail transit is y 10000 person times
According to the meaning of the title: x + y = 1696
4y-69=x
Then: x = 13.43 (10000 person times)
Y = 3.53 million person times
