No, the spin of different particles is a constant in each case; for example the spin of a photon is always 1.
The "intrinsic angular momentum" of particles is commonly called "spin". The spin of a photon is 1, in the units commonly used.
Fundamental particles such as the electron or the photon have an intrinsic spin, and this spin can't change - for example, an electron always has a spin of 1/2. I don't think the Pauli equation would change that.
emits radio wave photon.
Because chuck Norris spin kicked him.
One spin is what measures the length of one day
The Earth completes one orbital revolution in the time it takes to rotate roughly 3651/4 times. It would still revolve in the same length of time even if it weren't also spinning. There's no connection between these motions.
A photon is a unit of light and has a mass of 0 where is a Neutrino has a small but nonzero mass. Neutrino's are similar to electrons in most regards, except neutrino's have no charge. Where photon's travel at the speed of light neutrino's come close but do not.
I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.
The period of the earth's spin on its axis is [ 23hours 56minutes and roughly 4seconds ]. The period of the sun's apparent spin around the sky is 24 hours.
There is no direct relationship between the rotation of a planet (which governs day length) and a planets distance from the sun. The nature of the planets spin is more to do with the formation of the system early on, by large impacts of the more numerous bodies that would have been around.
