A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Relays were used extensively in telephone exchanges and early computers to perform logical operations.
A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective relays".
The Honourable Usain St. Leo Bolt, OJ, C.D. ( /ˈjuːseɪn/; born 21 August 1986), is a Jamaican sprinter and a five-time World and three-time Olympic gold medalist. He is the world record and Olympic record holder in the 100 metres, the 200 metres and (along with his teammates) the 4×100 metres relay. He is the reigning Olympic champion in these three events, and is one of only seven athletes (along with Valerie Adams, Veronica Campbell-Brown, Jacques Freitag, Yelena Isinbayeva, Jana Pittman, Dani Samuels) to win world championships at the youth, junior, and senior level of an athletic event.
Bolt won a 200 m gold medal at the 2002 World Junior Championships, making him the competition's youngest-ever gold medalist at the time (since surpassed by Jacko Gill). In 2004, at the CARIFTA Games, he became the first junior sprinter to run the 200 m in less than 20 seconds with a time of 19.93 s, breaking the previous world junior record held by Roy Martin by two-tenths of a second. He turned professional in 2004, and although he competed at the 2004 Summer Olympics, he missed most of the next two seasons due to injuries. In 2007, he broke Don Quarrie's 200 m Jamaican record with a run of 19.75 s.
Rolling mad blunts, that's my origami
All my verses fire, niggas spit wasabi
Join your'put you on designers
Started here with nothing, now a nigga grinding
Now a nigga grinding, niggas getting shows
Now I hit these shows and start demanding roles
Once I get the roles, back to backing hoes
Couple hundred for a verse, even more a show
Know some ATL business, hope a nigga blow
Audio dope, they stuff it in they nose
Real street nigga, bought it from the cold
Cops come knocking, you tell 'em you don't know
'hear my lines, say they love my flow
Rappers hit my phone, say they verse is dope
Please don't kill my vibe, I'm in a certain mode
Spraying when a fallen nigga about his dough
Nigga bout his dough
A nigga about his dough
A nigga 'bout his dough
You're breaking bones or breaking barriers, I'm breaking them, too
When we flip the switch then half a year it's taking them two
We know your role, we know your type, you're playing missed me, too
We don't know you, we don't owe you, take a picture, be cool
I see the ways they tryna pay, read the scripture, be you
Or grab a ratchet, get to tagging, rip a pistol in two
I'm hardly speaking on the subject when she all in my ear
You know your role, baby girl, you just part of my peers
Look, I'm gritty like eight was the section
Your Phantom doors hit the floor when we hit a recession
I'm headed overseas, all your flights are domestic
We'll jump a nigga out the gym, all your fights are domestic
You wanna go, throw your hands up, we gonna celebrate
Look, I need to focus more, watch me meditate
I hit him high as the sky now watch him levitate
You say you begging to differ then we can set a date
Nigga, I got bread to make
On my mark, I'm setting my squad already, place they bets
I take on fight 'cause PTO you more than new ATB4
Finna blow, we that C4, bomb wrap, we like Iraq
In the building like two planes, boy, you know I play no games
There it grows, I'm stunting on hoes, doing Brooklyn shows
Since my shit was in the sauce, my dropping like'
Shit, you lying here, my nigga, everything you hear is raw
I'm a lion's den, my nigga
Still a new jack, all my verses call a pooky
Nobody firing shots at the general, they salute me
A veteran in a year, Visine, my sight is clear
Your facing a side mirror, it's closer than it appears
Too legit, you should quit, watch me redefine hammer time
And let your bitch blow me like 30 mil' before my deal
It got too real and I forgot to have some fun with this
Kelso and Shome, the track team, know we running shit
You can hear it in the street, see it in the dragging feet
The word is gettin' out about control
Spies they've come and gone, the story travels on
The only quiet place is inside your soul
From tree to tree, from you to me
Travelin' twice as fast as on any freeway
Every single dream, wrapped up in the scheme
They all get carried on the relay
Relay, things are brewin'
Relay, something's doin'
Relay, there's a revolution
Relay, relay
(Hand me down a solution, yeah)
Pass it on, come on, a relay
Someone disapproves, what you say and do
I was asked to see what I could really learn you
Don't believe your eyes, they're tellin' only lies
What is done in the first place don't concern you
From tree to tree, from you to me
Travelin' twice as fast as on any freeway
Every single dream wrapped up in the scheme
They all get carried on the relay
Relay, things are brewin'
Relay, something's doin'
Relay, there's a revolution
Relay, relay
(Hand me down a solution, yeah)
Pass it on, pass it on, pass it on, hey you, pass it on
We're on the relay, get a movin'
Get on a movin' on
The relay, the relay
