4. Avogadro constant
6. Speed of light in vacuum (m/s)
All correct. (No. 1. is the base of the natural, or Napierian, logarithm.)
2. No idea
BoogieMonster got that one right. It’s the exact
expression of the Golden Ratio, φ.
3. alpha, cant remember the name.
Yes, the symbol commonly used for this physical constant is α
. It’s the fine structure constant.
5. no clue.
A tricky one, this. I won’t reveal it yet in case someone would like to guess. (Hint: It comes from number theory. Its decimal and continued fraction expansions are both aperiodic but it is not known whether the number is algebraic or transcendental.)
That’s the gas constant (in SI units).
The standard value of g
(in SI units), the acceleration due to Earth’s gravitational field at mean sea level.
6.62608 x 10-34
Planck constant (in SI units), the basic unit of energy quanta in QM.
1.602177 x 10-19
Unit of electrical charge, Coulombs.
