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.

No. Pi is approximately 3.14 and since .75 is not equal to 3.14, .75 is not equal to 3.14.
How does the mass of a nucleus compare to a electron?
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron.
In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron.
In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron.
So take your pick: 1,837 to 516,200.
Yes, because a mathematical constant is a "special number." It has a significant importance to something relating to math, such as pi's connection to circles and trigonometry.
This is an interesting question. Looking at complex numbers graphically, zero is at the intersection of the real and imaginary axis, so it is 0 + 0i. But if you square zero, you get zero, which is not a negative number (a pure imaginary, when squared will give a real negative number), so I'd have to say it is not imaginary.
Is 5 decades bigger than 48 years?
yes it is because the decade is 10 years and 5x10=50 so 50 > 48 (ho is greater than 48 ) in 2 years subtract : 50 - 48 = ? it is 2 this is my answer to my homework actually in math
What is an aggregate constant?
An aggregate constant is a nonscalar constant which value never change or are not changed during execution of the program.
The King of the Lollipops! He also had help from the Queen of the Cheese Sticks.
What is the ratio of silver to copper price?
The prices of silver and copper are always fluctuating. The price of silver is currently 0.67 USD / g. The price of copper is currently 0.0067 USD / g. The ratio of the price of silver to copper is 100:1.
How many zeros are there in USD2 million?
== == If by USD you mean US dollars, 2 million looks like 2,000,000. That is a total of 6 zeros.
How can the atomic mass change?
Depends, what do you mean "change"? Atomic mass "changes" whenever something undergoes decay or breaks apart. In this respect, atomic mass is not exactly conserved either. Rest mass gets converted to energy; e=mc^2, meaning energy is equal to mass times the speed of light squared. This energy is usually the kinetic energy of the particle that gets dislocated from the original atom.
Why does a negative discriminant yield imaginary numbers?
When solving equations (of e.g. 2nd grade) the discriminant is part of a squareroot.
A square root of 'x' is the number that multiplied y itself equals 'x'.
Any number we can think of - when multiplied by itself (squared) gives a positive number. (even negative number - e.g. -2*-2 = 4)
So we cannot think of a number which square is negative.
Then sq.root(-1) has no answer - no number squared gives -1.
Therefore the number that equals sq.root(-1) is imaginary.
How do you calculate the atomic mass of thalium?
To calculate the atomic mass of thallium, you need to consider the weighted average of the isotopes of thallium found in nature, based on their abundance. You multiply the mass of each isotope by its relative abundance, then sum these values to get the atomic mass. The atomic mass of thallium is approximately 204.38 grams per mole.
Can you show me the whole number of pi?
No, not the whole number because it goes on forever.
The shortened version of pi is 3.14.
