Karleb: If u don't have a reliable source to backup ur claim, why create a topic in the first place?

What ur prob man??....he jst needs to acquire some information so dat conclusion will be drawn from it...if u dnt hav smtin to render exhibit a centre of mass...mtcheeew..

hadizadeezy: watch ur ungrammatical sense of reasoning owk.....neva u in ur live quote my post....do we sounds like mate? Bekiaful..

No vex,forgive am o,one love,united we stand united 4 lyf

IMPORTANT INFORMATION TO ALL EXPDITES THAT HAS
NOT BEEN ADMITTED!!! expdites should fair not or still
sceptical if he or she would not be admitted because of
low jamb score of 179 &below. report reaching now is
that so far you have gotten a minimum of 250 in your
pds exam..YOU WILL DEFINITELY BE ADMITTED. but you
will be made to undergo REGULARISATION by paying #
5500 after you are been admitted.... the admission list
will be out on the school site after d e screening has been
done...please share for others to be informed!!!! I REST MY
META TARSAL....

Meta tarsal or carpals whch u used 2 type!

brownbest:
I wonder what's in that wallet!

Maybe condom hahahhaaaa!

Odilop: What's the name of this compound (CH3CO)2O ?

ethanoyl ethanoate

Odilop: The reduction potential of two electrode are
X2+ +2e- =X E=0.042v
Y+ + e-=Y E=O.012 v

Calculate the free energy change for the cell that is made up of the electrodes(f=96500coulumb /mol)

Ev=-change in G/nF whr n is d no of electron and
G energy(gibbs free)
F is faraday k(constant)
Ev volt involve.

Odilop: What's the hybridization of ethene and ethyne?

for ethene the carbon ar sp2 hybridized(double bonded c's) and
ethyne carbon ar sp hybridization(triple bonded C's)

ChocolateBarbie: just dey jae

Owk! O kip enjoying!

STORM2:
My guy, you're not supposed to spend "sleepless nights" reading. You're meant to spend months preparing diligently. Not spend a few "nights" crash reading. As for the ppl who u say didn't read and yet scored 250....they're simply more intelligent than average. E dey happen. I scored 204 on my first attempt...and I didn't solve even a single question...I did not prep. E dey happen. Don't hate the playa. On my second attempt I scored 244 cos I spent MONTHS PREPARING not "sleepless nights" forming activity a week to the paper. Nobody can blame JAMB for mass failure. Some ppl are just better at taking tests than others. And ofcourse, some ppl take time to do the work required to pass. People like u that have decided "malpractise" is the way forward...hmmm I reserve my comment. God bless all who work hard abeg.

storm,hw va??

ChocolateBarbie: instead of yu tew solve problem yu dey dre dey smile

abi nw hw va Choco babe!

mgb4reel: 50cm^3 of CO is mixed and sparked with 0.2dm^3 of air containing 21% of O2. If all the volumes are measured at s.t.p. Calculate the total volume of the residual gas.

........

mgb4reel:
Read between d lines bro. Total energy is 600j. Potential energy at 1/3 of d height is 400j and i already stated dat Total energy = P.E + K.E
do i need to show u again aw d K.E = Total energy - P.E ?
We are sharing, we are learning, we are growing.

.....

mgb4reel:
why d rhetorical question? Lookin at d question, d potential energy at d given height of 15m is 600j, which implies d total energy at any point can not b more dan 600j since d conversation of mechanical energy is constant in gravitational field.(hop u kno this);so ur answer is obviously wrong. Now, d question says when its at 1/3 of d height which means at 10m height. Here, d object is comin down, so we hav P.E and K.E. Which implies Total energy = P.E + K.E. P.E at dat point is 4*10*10 =400j. Hence, K.E at dat point will be 600 - 400 = 200j. U can read more on conservation of mechanical energy. WE ARE SHARING, WE ARE LEARNING, WE ARE GROWING.

the velocity at that point is wat??why is it negative and nt positive

250,000m/s

Odilop: no boss

Owk! Hmmm Warh abt dis 250,000m/s

mgb4reel:
i tink its C.

U calculated only 4 mgh warh abt d velocity It's 4 decoration

Odilop: A man drove his car north west for a distance of 10km then east for 40km and then south for 60km determine the overall displacement of the car from the starting point?

110,000m/s

Odilop: A man drove his car north west for a distance of 10km then east for 40km and then south for 60km determine the overall displacement of the car from the starting point?

110,000m/s

Odilop: No2 what single velocity is equivalent to the velocities 20m/s along the posite x-axis and 30 m/s along the positive y-axis?

36m/s

Hmmmm,I wonder why evry one jst dey choose UI,dis would be surviver of d fittest! Gbam!

buzyguy: Electrons wil singly occupy itz orbitalz b4 pairing quoted by who?

Fredrich hund in 1927

buzyguy: Sorry 4da absenc,phne flex prbm...yeah,pertainin to da questn u all tried wit concrete reasnz bt da kinetic energy the at the point 1/3 of da original height z jst da difrnc btwn da origan nd presnt height wich z 2/3 of 15=10 as da height,substitutn to Mgh we wil our desired ansa,so far da kinetc z convertd to da potential energy.U ALL knw kinetic energy z alwyz zero at any givn height unlez itz convertd to potential energy*note:dat velocity z jst 4 decoratn.apy readn nd roundn off.

hmm,bt we were ask what is d k.e,thr is a way 2 calculate it inwhich d answer will be,dat mgh+1/2mv2 will giv us our answer which is D or d ques is nt frame well
