I am invincible For my girls The fighters, the warriors
Broken glass inside
Won't cut
Through me
Pain behind my eyes
I turn
Into strength
Oh I will fight
I will survive
I am invincible
I am unbreakable
I am a diamond cut to last
I am unstoppable
I am a hero
Like a phoenix from the ash
Woah
Invincible
Cracks run through these walls
But they still stand strong
Oh, heart covered in scars
But my fear
Is gone
Oh I will fight
I will survive
I am invincible
I am unbreakable
I am a diamond cut to last
I am unstoppable
I am a hero
Like a phoenix from the ash
Woah
Nothin' gonna make me break or shatter
No one's gonna tell me I don't matter, no
I won't let you
Time is runnin' out, keeps gettin' faster
Gotta find a way, rewrite the answers
'Till I can say
I am invincible
I am unbreakable
I am a diamond cut to last
I am unstoppable
I am a hero
Like a phoenix from the ash
I am invincible
I am unbreakable
I am a diamond that will last
Woah
Woah
Invincible

Explanation:

b.a device that inputs heat into a cool object

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
