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.

Is gas constant equal to planks constant?
No, gas constant is having a value of 8.314Jk-1mol-1
Whereas plancks constant has a value of 6.6*10-31
What is characteristic gas constant?
The constant 'R' used in the characteristic gas equation PV=RT , has a constant value for a particular gas and is called 'Characteristic gas constant' or 'specific gas constant' . Its value depend upon the temperature scale used and the properties of the gas, under consideration.
The value of R will be.
For atmospheric pressure air,
R= 287 J/kg/k
What are the relations between the golden ratio and the Fibonacci series?
The ratio of successive terms in the Fibonacci sequence approaches the Golden ratio as the number of terms increases.
What is Wien's displacement constant?
In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law.
So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.
What are the units of the Coulomb constant k which appears in Coulomb's law?
newtons * meters squared / coulombs squared
Difference between permeability constant and permittivity constant?
Permittivity is the measure of access of electric field in any medium while the other is the same of magnetic field in any medium.
This is because of symmetry between the electric field and magnetic field that they depend on the medium in which they exist.
The both have different units and different relations with their respective fields.
Here is a relation between the both for those who are interested in MODERN PHYSICS but it has nothing to do in electromagnetics alone.

What in an expression of Dalton's law constant?
Dalton's law of constant proportion states that any sample of a chemical compound will have its constituent elements appearing in the same proportion by mass. Thus 8/9 of the mass of any sample of water will be oxygen and the remaining 1/9 will be hydrogen.
How to solve this pattern sum of 11 12 13 14 15 16 17 18 19 20?
A linear series with "i" terms can be summed by finding the average of the first and last terms, then multiplying by the amount of terms.This sequence can be written as follows:
ai= 11 + 1(i-1)
= 11 + i - 1
= 10 + i
11 is the first term, 1 is the difference between terms which gets multiplied by (i-1)
So the fourth term a4= 10 + 4 = 14
Sum total = i * (a1+ ai)/2 (no. of terms * average of first and last term)
= 10 * (11 + 20)/2
= 10 * (31/2)
= 155
What is the definition of constant motion?
It is a kind of force that will stay in the same point, but is not reactive to the force.
Is zero divided by zero equal to zero?
Actually 0/0 is undefined because there is no logical way to define it. In ordinary mathematics, you cannot divide by zero.
The limit of x/x as x approaches 0 exists and equals 1 so you might be tempted to define 0/0 to be 1.
However, the limit of x2/x as x approaches 0 is 0, and the limit of x/x2 as x approaches 0 does not exist .
r/0 where r is not 0 is also undefined. It is certainly misleading, if not incorrect to say that r/0 = infinity.
If r > 0 then the limit of r/x as x approaches 0 from the right is plus infinity which means the expression increases without bounds. However, the limit as x approaches 0 from the left is minus infinity.
