The three components F1 = 3N, F2 = 5N, F3 = 6N, the statement about their resultant force is correct A may be equal to 0n B may be equal to 2 C may be equal to 13 D may be equal to 15

The three components F1 = 3N, F2 = 5N, F3 = 6N, the statement about their resultant force is correct A may be equal to 0n B may be equal to 2 C may be equal to 13 D may be equal to 15

ABC
The minimum of three forces can be zero
The biggest is that they are all in the same direction, 3 + 5 + 6 = 14 is smaller than 15, so 15 is not good

What is 13.5 times 0.68 divided by 8.5?

13.5*0.68/8.5
=1.08

What's the meaning of "Zhi" in the process of thinking about helping bow and shooting
In a hurry

Pronoun, it, refers to the Swan mentioned above
The article comes from Mencius Gaozi Shang written by Mencius Ke in pre Qin Dynasty: "make Yi Qiu teach two people Yi, one of them is dedicated, but Yi Qiu is listening. Although one person listens to it, he thinks that there is a swan coming, and he wants to help bow and shoot it. Although he has learned from it, it's very rare."
It's called chess in the textbook

For a two digit number, the number on the one digit is even and prime, and the number on the ten digit number is odd and composite. This two digit number is prime______ ．

According to the definition of prime number and composite number, even number and odd number, in 0-9, prime even number is 2, odd composite number is 9, so this two digit number is 92

Let f (x) = AX2 + 1 / BX = C be an odd function (a, B, C are integers), and f (1) = 2, f (2)

Fill in the blanks: 8, 15, 10, 13, 12, 11

12 + 2 = 14, so the answer is: 14

Several natural numbers are arranged in a row. Starting from the third number, each number is equal to the difference between the two numbers in front of it. It is known that the first number is 180 and the sixth number is 10. What is the second number? (using the equation solution, the process also needs to have,)

182, starting from the fourth number, the coefficient of X1 is the coefficient of x2 of the previous number, and the coefficient of X2 is the sum of the coefficients of x2 in the previous two numbers. Finally, we can deduce that the seventh number is 5x1 + 8x2, and the sum is 55x1 + 88x2 = 2002, so 5x1 + 8x2 will not come out
Which school are you from in Nanjing?

It is known that the solution of the equation kx-4 = x is a positive integer, and the integer k =?

kx-4=x
(k-1)x=4
x=4/(k-1)
Because x k is a positive integer,
K = 5 or K = 3 or K = 2

The upper part of a wine bottle is conical, and the lower part is cylindrical. The radii of the two bottom surfaces are the same, and the heights are 9cm and 15cm respectively. The liquid level of wine in the bottle is 11cm. Now when the wine bottle is inverted, the liquid level of wine in the bottle is () cm

Solution volume = 11 × s bottom (indicating the bottom area) cone volume = 9 × s bottom × 1 / 3 = 3S bottom, then the height of the spare part is 3S bottom △ s bottom = 3cm, then the liquid level height of the wine is 11-3 + 9 = 17cm. The upper part of a wine bottle is conical, and the lower part is cylindrical. The radii of the two bottom surfaces are the same, and the heights are 9cm respectively

All natural numbers are either prime numbers or composite numbers______ (judge right or wrong)

According to the analysis: prime number and composite number are classified according to the number of factors of a natural number, because 1 has only one factor itself, so 1 is neither prime nor composite number. Therefore, all natural numbers are not prime numbers or composite numbers. This statement is wrong. So the answer is: wrong
