The dark spots on the moon are the craters and there light spots are made up of the moon dust technically called regolith
A magnet sitting next to a wire does not induce a current in the wire because <span> the magnet is very small and short compared to the coil radius. If you pretend it's two individual monopoles, they're only a few mm apart, so at several cm there's almost perfect cancellation of the fields.</span>

This image sums it up
The electron cloud is split up in 3 areas.
1) Inner Electron Cloud
2) Outer Electron Cloud
3) Valence Electrons
Your inner cloud is the electrons CLOSEST to the nucleus.
Your outer cloud is the electrons in the MIDDLE of the Inner and Valence.
Your valence electrons are the OUTER LAYER of electrons. These electrons are important to bonding, and also are what decide where on the periodic table of elements. For example:
197
Au
79
This element is GOLD. It has 1 valence, therefor it is where it is in the period. Ionization could change this number however.
Answer:
We know that loudness is directly proportional to amplitude and SI unit of amplitude is Decibel So unit of loudness is decibel
