Mathematical Constants
Intriguing, ubiquitous, and at times mysterious, numerical constants set the allowable limits for all universal phenomena. Whether your questions involves π, Avogadro's number, Planck's constant, the atomic mass unit, or any of the other multitudes of immutable numbers used in science, this is the category where they should be asked.

Why G is called universal constant?
G is called The universal gravitational constant because at any point of the universe the value of G is constant.
G=6.67*10^-11 N m^2/kg^2...!!!!1
Why is g called the universal constant?
It is the measure of the gravitational force experienced between any two bodies, anywhere in the universe. So, the same number is used to calculate the gravitational attraction between bodies anywhere in the universe. There are, however, some questions as to whether is is (or was) a constant over time.
What is the number closest in value to 0.2?
0.2 is the closest that you will get.
The nearest integer, though, is 0.
Why is 0 the identity number for subtraction?
If you subtract 0 from any number, that number remains unchanged. Hence, the identity of the number is preserved.
How do you use odd and even numbers in real life?
House numbers are often odds on one side of the street, evens on the other.
When do you say two quantites to be in the golden ratio?
Two quantities are said to be in the Golden Ratio if the ratio of the larger to the smaller is the same as the ratio of their sum to the larger.
Algebraically, if X and Y are the two quantities and X<Y, then
Y/X = (X+Y)/Y
This gives the ratio as 0.5*[1 + sqrt(5)] = 1.61803...
How do you write 3 000 000 000 200 000 000 600 000 20 000 9 in standard form?
In standard form it is;
3.000000000200000000600000200009 x 1030.
What is the square root of 68 to the power of 2?
The square root is nearly the inverse operation of squaring or raising to the second power. Nearly but not quite!
So sqrt(682) = ±68
What two numbers equal 205 when mulitpling?
1 x 205 = 205, for starters.
Since 205 is divisible by 5, we can find a number to multiply by 5 to get 205. This will be 205/5, or 41.
5 x 41 = 205.
Since 5 and 41 are the only prime factors of 205, there are no other positive solutions.
Can you divide an imaginary number by a real number?
an imaginary number is imaginary so no (i guess) this answer kind of sucks
What are the dimensions and units of gravitational constant G?
The dimensions are [L^3M^(-1)T^(-2)] and the units are m^3 kg^(-1) s^(-2).
What are 6 household items with the golden ratio?
It is not set in stone, but here are some household items that could have possibly been created with the golden ratio in mind because they are supposed to be visually appealing.
An index card
A photograph
A picture frame
A textbook
A door frame
A computer screen
A TV screen
Are molecules per mole a unit for avogadro's number?
No, the unit is "per mole". The number could be atoms or molecules but that is not part of the unit.
