The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer in three seconds or approximately one mile in five seconds.
In fluid dynamics, the speed of sound in a fluid medium (gas or liquid) is used as a relative measure of speed itself. The speed of an object (in distance per time) divided by the speed of sound in the fluid is called the Mach number. Objects moving at speeds greater than Mach1 are traveling at supersonic speeds.
The speed of sound in an ideal gas is independent of frequency, but it weakly depends on frequency for all real physical situations. It is a function of the square root of the absolute temperature, but is nearly independent of pressure or density for a given gas. For different gases, the speed of sound is inversely dependent on square root of the mean molecular weight of the gas, and affected to a lesser extent by the number of ways in which the molecules of the gas can store heat from compression, since sound in gases is a type of compression. Although, in the case of gases only, the speed of sound may be expressed in terms of a ratio of both density and pressure, these quantities are not fully independent of each other, and canceling their common contributions from physical conditions leads to a velocity expression using the independent variables of temperature, composition, and heat capacity noted above.
Aaron Dontez Yates (born November 8, 1971), better known by his stage name Tech N9ne (pronounced "Tech Nine"), is an American rapper from Kansas City, Missouri. In 1999, Yates and Travis O'Guin founded the record label Strange Music. Throughout his career, Yates has sold over one million albums and has had his music featured in film, television, and video games. In 2009, he won the Left Field Woodie award at the mtvU Woodie Awards.
His stage name originated from the TEC-9 semi-automatic handgun, given to him by rapper Black Walt due to his fast rhyming style. Yates later applied a deeper meaning to the name, claiming that it stands for the complete technique of rhyme, with 'tech' meaning technique and 'nine' representing the number of completion.
Aaron Dontez Yates was born on November 8, 1971 in Kansas City, Missouri. He began rapping at a very early age, and would rap the letters of his name in order to remember how to spell it. He never met his father, and his mother suffered from epilepsy and lupus when he was a child, which emotionally affected him and inspired him to "search for God." He would wander around abandoned buildings with his best friend, Brian Dennis, hoping to catch a ghost on film. In 2003, Dennis was shot and killed by his girlfriend's ex-boyfriend, which further inspired Yates' search for a higher power, as well as giving him the drive to vent his frustrations in his music.
Sir James Paul McCartney, MBE, Hon RAM, FRCM (born 18 June 1942) is an English musician, singer-songwriter and composer. Formerly of the Beatles (1960–1970) and Wings (1971–1981), he has been described by Guinness World Records as "The Most Successful Composer and Recording Artist of All Time", with 60 gold discs and sales of over 100 million albums and 100 million singles. With John Lennon, George Harrison, and Ringo Starr, he gained worldwide fame as a member of the Beatles, and with Lennon formed one of the most celebrated songwriting partnerships of the 20th century. After leaving the Beatles, he began a solo career and later formed the band Wings with his first wife, Linda Eastman, and singer-songwriter Denny Laine.
According to the BBC, his Beatles song "Yesterday" has been covered by over 2,200 artists—more than any other song. Wings' 1977 release, "Mull of Kintyre", became one of the best-selling singles ever in the UK, and he is "the most successful songwriter" in UK chart history, according to Guinness. As a songwriter or co-writer, he is included on thirty-one number one titles on the Billboard Hot 100, and as of 2012 he has sold over 15.5 million RIAA certified units in the United States.
Am I but a coward walking down the yellow brick road?
Where's my megaphone?
Am I but a scarecrow running from the seed that I sowed?
Where's my megaphone? Where's my megaphone?
Truth moves at the speed of sound
Truth moves at the speed of sound
Truth moves at the speed of sound
Am I but a mirror-flattering, the fairest of them all?
Where's my megaphone?
Am I but a princess wearing a disguise to the ball?
Where's my megaphone? Where's my megaphone?
Truth moves at the speed of sound
Truth moves at the speed of sound
Truth moves at the speed of sound
Where's my megaphone? Where's my megaphone?
Where's my megaphone? Where's the megaphone?
Truth moves at the speed of sound
Truth moves at the speed of sound
Truth moves at the speed of sound
i've come far to be here with you
farther than i thought i could
i've more courage now than i have ever
let on to you
and it's in the way you're moving
as uneasy as your smile
i can tell you're slowly dying
can we stop and talk awhile
now as far as i can remember
you've been running all your life
and it seemed you ran forever
'cause i was always left behind
now that i have caught up to you
there are things i have to say
like i'm happy to be near you
but i cannot stay
my love's an ocean
you are the moon
the stars - our windows
the sky is our room
these are more than simple changes
they are painful and profound
and you might consider pacing life
below the speed of sound
no i can't take your wounds from you
things you've done i cannot undo
i can only hope to love you
like the ocean loves the moon
i am an ocean
you are the moon
our life - the morning
Turbine starts, engines whine
Rocket fire, you know it's blast off time
Burning fuel, deadly tool
Break the sky, shock wave blast, ripping fast
The speed of sound, speed of sound
The speed of sound, speed of sound
Sonic boom, machine of doom
The power to fly, bird's eye view,climbing to
The speed of sound, speed of sound
The speed of sound, speed of sound
The speed of sound, speed of sound
The speed of sound, speed of sound
High speed flight, vapour trail
Thunderous thrust, hear the engine's wail
After burn, no return
I remember the first time
You said you loved me
I waited all weekend
You never called me
So you find him attractive
So what if he is
You'd like some excitement
You could count his same kiss
So it goes
On and on
My love grows
And yours is gone
A lonely existence
Well it's just a lie
If there is a reason
I'd like to know why
Something I want you to know
I've told you this once before
Don't want you to see him no more
Once again
You've let me down
Broke my heart
And turned me round
There's a light in the darkness
It doesn't seem far
Is something the matter
? ? ? ajar
The plane goes down
Will not land
Pilot's dead
How long before I get in?
Before it starts, before I begin
How long before you decide?
Before I know what it feels like
Where to? Where do I go?
If you've never tried then you'll never know
How long do I have to climb
Up on the side of this mountain of mine?
Look up, I look up at night
Planets are moving at the speed of light
Climb up, up in the trees
Every chance that you get is a chance you seize
How long am I gonna stand
With my head stuck under the sand?
I'll stop before I can stop
Or before I see things the right way up
All that noise and all that sound
All those places I got found
And birds go flying at the speed of sound
To show you how it all began
Birds came flying from the underground
If you could see it then you'd understand
Ideas that you'll never find
Or the inventors could never design
The buildings that you put up
Or Japan and China, all lit up
The sign that I couldn't read
Or a light that I couldn't see
Some things you have to believe
But others are puzzles, puzzling me
All that noise and all that sound
All those places I got found
And birds go flying at the speed of sound
To show you how it all began
Birds came flying from the underground
If you could see it then you'd understand
Oh, when you see it then you'll understand
All those signs I knew what they meant
Some things you can't invent
Some get made and some get sent, ooh
Birds go flying at the speed of sound
To show you how it all began
Birds came flying from the underground
If you could see it then you'd understand
Oh, when you see it then you'll understand
Block Beaters
Make my dream real
Bl-bl-bl-bl-block Beaters
Moving at the speed of sound
With my head up in the clouds
Moving at the speed of sound
With my head up in the clouds
Yeah yeah, my life's like
[Chorus:]
Moving at the speed of sound
Yeah yeah, yeah yeah
With my head up in the clouds
Yeah yeah, my life's like
Moving at the speed of sound
Yeah yeah, yeah yeah
With my head up in the clouds
My ma keeps telling me
I better stay in school
But when that ends, Lord knows
I don't know what I'm going to do
[Hook:]
Cause everytime I blink now
Another day rolls by
It's getting harder not to think about
All the things on my mind
Like, I remember this time last year
I was all alone
I felt like I was two feet tall
Now there's a hundred million numbers
Inside of my phone
But I still got no one to call
My life's like
[Chorus]
My friends keep telling me
How much they believe in me
I wish that I saw the things that they see in me
[Hook]
[Chorus]
[Big Sean:]
My life's like
My life's like
Ay, do it, ay, music, ay
High rise, elevator life
I'm gone in 60 seconds
Or Talladega nights
I know I'm living wrong
I wish I could make it right
But baby, hold that thought...
Cause I gotta take this flight
When I leave my passport
Overseas passports
Hotels with the glass floors
Everything I ask for
Fast cars, fast hoes
My whole life is fast foward
But if I stop, stop
I might hit that dashboard
And I be, I be
I be, I be always take and choose
In and out relations with
Girls who want relationships
And I can fake a smile
And I end a conversation well
We just can't see eye to eye
We might need that LASIK shit
Cause tomorrow I'll be gone gone gone
Dip into another time zone zone zone
Tryna make my hotel feel like home home home
Phone won't stop ringing but I still feel all alone
My life's like
[Chorus]
(Move it up, bring it up, bring it up, up up
Yesterdays, how quick they change
All lost and long gone now
It's hard to remember anything moving at the speed of sound
Moving with the speed of sound
And yet I'm still holdin' tight to this dream of distant light
in that somehow I'll survive
But this night has been a long one
Waiting on a sun that just don't come
Can I forgive what I cannot forget
And live a lie?
I could give it one more try
Why deny this drive inside, just looking for some peace
Every time I get me some it gets the best of me
I'm not much left, you see
And yet I'm still holdin' tight to this dream of distant light
And that, somehow I'll survive
But this night has been a long one
Waiting on a word that never comes
A whisper in the dark
Is that you or just my thoughts
I'm wide awake and reaching out
It's gone so quiet now
Could it be I'm farther out?
[Chorus:]
If you find love
If you see my love
Say I am not stopping until my heart is found
If you tell me where I could find love
I'll be running faster than the speed of sound
I'll be running faster than the speed of sound [repeats]
Love is a metaphor
Meaning the whole reason that I met her for
She said that she is better than the others are
... tell me more
I let her know when I am close to her
I wanna know everything that I am supposed to
You got my heart beating like a sound pipe
She's... know that she's gonna be a better...
I'll take you to the ground light
I'll take you from the... right
Right now I am all crowd out
I'm... on the stars for the right time
I'm gonna come and find you and let you know
That my love is right here I ain't letting go
But if I do have to let you go
Then I got to let you know
[Chorus]
I'm lost in your love story what a...
What is love got to do with a pay check?
You made me fall hard like a plane crash
My heart... in the flames in the same ash
That's when I keep to going in right
So know I am gone with the red light
Like... on a dead night
I'm going out like...
I wake up just to find you smile
I... right now with the speed of sound
I'm trying to make it all crowd now
Waiting up for the stars and the right time
I'm gonna find you and let you know
My love been here I ain't letting go
If it is you that wanna let it go
There is one thing that I got to let you know
[Chorus]
Please girl let me know if you're gonna wait for me
Cause of not you'll never gonna hear from me
I'm just trying to bring your love back
Tis time... been there done that
... let me know
That your love is right here don't let it go
This is the last I'm gonna let you know
... got to let you go
Hey pull the trigger
I am your bullet
Going to nowhere
I'm shooting up into the sky
The rhythm
Accelerator
This rocket is ready to fly
Goodbye to your slow-creeping days
Nothing will stand in my way!
Racing faster
Breaking out of this mad prison-cell
Faster
Just like a flash out to hell
Ah speed of sound metal heat !
Atomic speed set me free
Speed of sound treat me right
Sonic speed set me free
Red blood and gasoline
We really got to go
This rat-race is getting us down
Child of the rhythm
Don't wait forever
Tonight is the night!
Racing faster
Breakin' out of this mad prison-cell
Faster
Just like a flash out of hell
Speed of sound, metal heat !
Sonic speed set me free
Speed of sound treat me right
Just as fast as the speed of light !
Speed of sound, metal heat !
Sonic speed set me free
Speed of sound metal heat !
Can't you see how i feel
Atomic speed ! Set me free ! Speed of sound !
I've followed traces of the steps before
I've passed away now, into peaceful war
Nearing now I see I have longed to be
Taken by the hand of the faceless one who stands
Now I undergo the change of life foretold
Growing on to me and now I soon shall be
Soaring blindly in a race through borrowed time
And beside me a race of souls who ride
Growing on me the wings of flight in empty space
Is it terror propelling us into the chase
Chorus:
I'm timeless bound from the speed of sound
And the move that's endless all around
And with this space I share all the souls who bare
Heavy weight turning loose falling to the ground
As the sun falls dark we have made our mark
It captures me to know I have doused the final spark
Chorus
It's never ending our lungs have burst with might
Souls of this speed spectors soar through the night
Into stardom then beyond who knows?
The speed of sound is broke and onward we are bold!
Chorus
Do you think I'm gone? Most of this would pleasure you
alone.
It's that I can't even see, there's midnight behind my
eyelids.
No ones home, and I'll lie to everyone, not even my
lovers will see what's wrong.
All my skin is drenched in light, that's what's wrong. I
died in a fire, I died in a fire.
It's already done. I've got ideas I'd never put in word,
but you sparkle when I speak.
How can I resist it, your alone. And I'll lie to
everyone, not even my lovers will see what's wrong.
All my skin is drenched in light. That's what's wrong. I
I remember the first time
You said you loved me
I waited all weekend
You never called me
So you find him attractive
So what if he is
You'd like some excitement

So it goes
On and on
