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.

What action would you use to solve x 4 16 what property justifies that action?
x*4 = 16Divide both sides by 4 to give x = 4
Equals multiplied by equals are equal.
What is the physical meaning of a spring constant?
It means how "stiff" the spring is; how hard it is to compress or extend it.
How many zeros in ten million?
there are seven zeros in 10million (10,000,000
there could be more than that depending on how many zeros you put after the decimal point.
How many millimetres are there in 0.1 decimetres?
There are 100 millimetres in one decimetre. Therefore, 0.1 decimetres is equal to 0.1 x 100 = 10 millimetres.
What is the constant equal to the ratio of the gas constant to the avogadro constant?
Boltzmanns constant
Avogadro did experiments to determine avogadro's number?
No! Avogadro just guessed the average number of molecules,ions,atoms number in one mole of any compound,element,etc.
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
Which ratio of your body measurements fits the Golden Ratio?
None.
There are some measurements which, in some people, are approximately equal to the Golden Ratio but those same measurements, for other people, are not.
What if the value of planck's constant is increased to 1?
The value of Planck's constant depends on the system of units that are being used. The SI units are designed mainly for everyday measurements, where energies are usually of the order of kilojoules and a small period of time is a minute or second. However, the Planck's constant applies events at a subatomic scale so that these "normal" measurement units are not inappropriate.
So the question changes in which units would the Plank's constant become 1. Further, the answer depends on how that change is achieved.
Planck length and Planck time Planck time is the time it would take a photon moving at the speed of light in a vacuum to cross a distance equal to the Planck length. The Planck length is 1.616252 × 10−35 meters, and the Planck time is 5.39121 × 10−44 seconds. Links are provided to the relevant Wikipedia articles.
How are moles converted into number of particles?
The moles are converted into a number of particles by multiplying 6.02 by 10(with the power of 23)
What number is missing out of the first thrity digits of pi?
There is no 0 in pi until the 32nd digit.
What is Coefficient of coupling?
It is a measure of how close is a coupling between two coils it gives an idea of wat portion of the flux produced by one coil links with the other coil
What is four one fifth plus five one tird plus a half?
First make them all top heavy fractions:
4 and 1/5 = ((4*5)+1)/5 = 21/5
5 and 1/3 = ((5*3)+1)/3 = 16/3
1/2 stays as 1/2.
Secondly put them all over the same denominator by multiplying the top and bottom of each fraction by the same multiplier. The multiplier can chage for each fraction.
Here the lowest common multiple is 30, so the lowest number you can make all the denominators is 30:
21/5 * 6/6 = 126/30
16/3 * 10/10 = 160/30
1/2 * 15/15 = 15/30
Now you can add all three factors together because they have the same denominator:
126/30+160/30+15/30 = 301/30
Finally, you can simplify your answer:
10 and 1/3.
