Is a Wet dream and Nocturnal Emission the same?

Is the nocturnal emission a result of the wet dream, or are they both one in the same?
same shi. different day.

What’s the big deal about India and emission cuts? Could someone tell me about the entire affair?

I’m not very clear about this, and I want to know the current state of affairs regarding this topic and also the past incidents that have influenced it, like the UNFCCC (if that’s right) and all. Why is India not agreeing to emission cuts?
EMERGING ECONOMIES ARE NOT WILLING TO AGREE TO FIXED EMISSION CUTS BEFORE [...]

Astronomy homework question regarding maximum emission of wavelength?

The bright star Bellatrix in the constellation Orion has a surface temperature of 21,500 K.
What is its wavelength of maximum emission in nanometers?
What color is this star?
Wein’s displacement law.
Lmax = (0.00289777 m K) / T
T = 21500 K
Lmax = 1.3478E-7 meters
Lmax = 134.78 nanometers
blue star

What is the difference with CA emission Corolla?

I live in Arizona and was going to look at a 2007 Toyota Corolla but originally from California. What extra emission systems would this have and would it be a bad idea to have extra emission stuff when not required? Just wondering if there is much more to maintain? Thanks
California has one [...]

What does the emission spectrum represent?

If you were given an emission spectrum how would you describe it?
It’s the light emitted from a sample through relaxation of the electrons from higher energy states to lower energy states.
It’s a unique pattern for every material, and allows us to work out the constituent parts of mixtures of materials without having to isolate each [...]

Composition of a star using emission spectra?

What are emission spectra? How are they originated?
Also, The opposite of emission spectra is absorption spectra. What are absorption spectra? How can you tell the composition of a star by looking its absorption spectra?
Hi. Every atom has electrons. These will occupy different shells, or more probably clouds. It takes a certain amount of energy to [...]

Composition of a star using emission spectra?

What are emission spectra? How are they originated?
Also, The opposite of emission spectra is absorption spectra. What are absorption spectra? How can you tell the composition of a star by looking its absorption spectra?
absorption spectra are photons that are created from a source, in this case fusion reactions within the star’s core. these photons collide [...]

Should positron emission lead to an increase in mass?

For positron emission, a proton which has slightly higher mass than a neutron kicks out a positron and turns in into a neutron. How can a particle lose something and pick up mass?
No, no, no. A proton is not more massive than a neutron. Also, a positron is a just like an electron [...]

What is the difference in the value of a certain atom’s Atomic Emission Wavelength and Absorption Wavelength?

What is the difference in the value of a certain atom’s Atomic Emission Wavelength and Atomic Absorption Wavelength?
Behold! Understanding Kirchoff’s laws brings great wisdom.
This "Stoke’s shift" mentioned by the next answerer sounds like a violation of the conservation of energy. But I can think of one way it might be true. If [...]
