Answer:
A neutral atom of aluminum has 13 protons and 13 electrons. The ground state electron configuration for aluminum is 1s22s22p63s23p1. A shorthand way to write the electron configuration, called noble gas notation, is [Ne]323p1.
Explanation:
#6 - Lower frequencies correspond to <em>longer</em> wavelengths.
#7 - To change the pitch of a sound, you have to change its <em>frequency</em>.
Answer:
Vibrations of electric and magnetic fields.
Vibration of air particles
Vibration of the water particles.
Explanation:
We have here two groups of waves. Electromagnetic wave and mechanical waves.
- For the first one, electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
- For the second group, mechanical waves as a sound, for instance, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. Or In water waves, energy is transferred through the vibration of the water particles.

anything that contains one cell of life is considered a living thing, a fire however does not contain any cells so it is not considered a living thing/organism
hope this helped you :)
