M square calculation force

1. M (m-1)

2. For people to see: just use the superscript function of word
Press shift Ctrl and "+" at the same time to superscript, and then press the number
at the same time, press Ctrl and "+" as the subscript, and then press the number
1: input the number to be squared first
2: check the superscript in format font effect
3: enter 2 to be OK

for computer recognition: for example, the power of X should be m ^ 2,
in other words, type m first, then press Shift + 6, and then type 2

3. It is estimated that 4500n is calculated according to 50kg person. First, calculate the acceleration 900m second square, and then calculate the force with V2 = 2aX acceleration

4.

Body mass index (BMI) = weight (kg) / height square (M2)

normal weight: 18.2-22.9 overweight: 23-24.9 grade I obesity: 25-29.9 grade II obesity: & gt; 30

for example: height: 162cm, its square, 1.62x1.62 = 2.6244, weight: 45kg45 ÷ 6244 = 17.14677

BMI was standard weight (kg) = height (CM) - 105. The actual weight is in the range of the standard weight calculated according to the formula ± 10% is normal, more than 20% is obesity, 20% - 30% is mild obesity, 30% - 50% is moderate obesity, more than 50% is severe obesity

extended data:

other calculation methods:

1. Calculation method:

standard weight = height (m) × Height (m) × Standard coefficient (female 20, male 22)

standard weight plus or minus 10% is normal weight

standard weight plus or minus 10 ~ 20% is overweight or light weight

standard weight plus or minus 20% is obese or underweight

2. Calculation method:

standard weight (kg) = height (CM) - 105

for example, a man with height of 170 cm, His standard weight should be: 170 (CM) - 105 = 65 (kg). Those over 10% of the standard weight are overweight, and those over 20% are obese; Those whose body weight is less than 10% of the standard weight are thin, and those whose body weight is less than 20% are thin

note: the above calculation method is only applicable to alts. Not for children, the elderly, or people who are too short

5. 1 mm is equal to 0.001 m, so 1 square mm = 0.00000 1 square m (1 mm ^ 2 = 0.00000 1 m ^ 2).

7. m^2=m
m^2-m=0
m(m-1)=0
m=0
or m-1=0
m=1

9. Using kugou Pinyin, you can square it directly

10. 2m is 2 times m, which is multiplication operation; The square of M is m times m, which is a square operation.
