Answer:
Explanation:
the energy gap between the ground state and excited state in the laser material will be equal to energy of photons emitted
Wave length of photons = 520 nm
Energy = 1244 / 520 e V ( Formula for conversion of wavelength in nm to energy in eV )
= 2.4 e V
the energy gap between the ground state and excited state in the laser material = 2.4 e V
The sin function and the cos function are used to resolve vectors into their componets

Explanation:
The evolutionary stages for the formation of planets from earliest to latest will be:
1. Dust keeps matter inside the disk cool enough for planet formation to start
2. Dust grains form condensation nuclei on which surrounding atoms condense to form small clumps of matter.
3. Small clumps of matter stick together via the process of accretion to form planetesimals a few hundred kilometers in diameter.
4. Planetesimals begin to accrete, forming protoplanets.
5. A collection of a few planet-sized protoplanets remain in a fairly cleared out disk around the star
