Are h's equations right?

Garry Denke - 2-3-2007 at 21:42

These are not my equations, they are h's equations.

h = e^2 * z0 / (2 alpha)
h = [(1.6021765(31) x 10^-19 A-s)^2] * (3.767303134... x 10^2 kg-m^2/A^2-s^3) / [(2.00000000 x 10^0 rad/sr) * (7.2973525(68) x 10^-3 sr)]
h = (2.5669696(36) x 10^-38 A^2-s^2) * (3.767303134... x 10^2 kg-m^2/A^2-s^3) / (1.4594705(14) x 10^-2 rad)
h = 6.6260693(11) x 10^-34 kg-m^2/s-rad

h = e^2 / (2 alpha) * e0 * c
h = [(1.6021765(31) x 10^-19 A-s)^2] / [(2.00000000 x 10^0 rad/sr) * (7.2973525(68) x 10^-3 sr)] * (8.854187817... x 10^-12 A^2-s^4/kg-m^3) * (2.99792458 x 10^8 m/s)
h = (2.5669696(36) x 10^-38 A^2-s^2) / (1.4594705(14) x 10^-2 rad) * (8.854187817... x 10^-12 A^2-s^4/kg-m^3) * (2.99792458 x 10^8 m/s)
h = 6.6260693(11) x 10^-34 kg-m^2/s-rad

h = e^2 * u0 * c / (2 alpha)
h = [(1.6021765(31) x 10^-19 A-s)^2] * (1.256637061... x 10^-6 kg-m/A^2-s^2) * (2.99792458 x 10^8 m/s) / [(2.00000000 x 10^0 rad/sr) * (7.2973525(68) x 10^-3 sr)]
h = (2.5669696(36) x 10^-38 A^2-s^2) * (1.256637061... x 10^-6 kg-m/A^2-s^2) * (2.99792458 x 10^8 m/s) / (1.4594705(14) x 10^-2 rad)
h = 6.6260693(11) x 10^-34 kg-m^2/s-rad

Are h's equations right, I cannot find h anywhere.

Thanks!

h as in Planck's constant? Your values agree with what I remember, but I wish you at least said what "z0", "u0", and all those meant. ;)

And yeah, radians are not *actual* dimensions in the SI way of doing things, so you can knock off the radian "unit" in your final answer.

Hope this helps.
