Okay...CDL asked most pple to bring their jamb slip esp those who didn't pick oau in jamb...xo frm nxt week there shud be changes

ok oooo.....let hope so

chisombenedicta:
Avnt u gotten ur adm...I tot cmpite av seen their names

have not oooo......but some have been given

HIGHLIGHTS OF PROPOSED AMENDMENTS TO
THE APPROVED ACADEMIC CALENDAR FOR
2014/2015 SESSION
so one month break no go reach dem nii??

chisombenedicta:
Yea I know...Buh there's a probability w'ld resume early April...u know they had Nasu issh,nd that disrupted their calendar a bit

it doesnt affect because the strike was used as their mid semester break

cdl should just do fast ooooo

chisombenedicta:
Naaa not yet..its jes that last set wer to resume May 3rd nd they extended it to 17

that was last set.....quiet different from this set....what happened last set does not necessary mean it must happen the set.......

HighIQ:
what of if the rapture should take place b4 then

that will make things better.......we just forget about school and husle tins and go flex for heaven ........FTC.....happy new page and new month

chisombenedicta:
Hmmmm don't be rest assured....

i believe God will avert any isue that might cause any further extension in resumption date,be it strike

Funshorrh:
sori dear... Some situation are just inevitable

presently, we are scheduled to resume march 27 according to the calendar......i assure u, nothing will change that......no strike by God's grace

Abuhaneefah21:
oooorrr..I am an intending predate sire

oooh....ok.....wish u best of luck.....hmmm....pre degree is survival of the fittest......God help u.

Abuhaneefah21:
CMP

have u been given admission?......and what ur course......am a CMPite too

pls house,a friend of mine did not chose uniosun but obtained their post ume form....and scored 203 in jamb.........what is the chance of getting admitted ?thanks in anticipation of ur kind response...

sazy:
Maths guru plenty here ooo [quote.....i hail whona ooo boss them......

osas, se you de that wattapp group nii?.........i asked one of the guys in chharge to add me...he was asking some unnecessary questions

on behalf of sholay hostel i greet all predite merry exmas and happy new year in advance .........

pls is there anyone who knows sholly hostel..........and how far is it from campus? thankss in anticipation

kunlexic.........observing u

modewap: lol, i wished but i don't know God wish for me. Boss, me self expecting 300+ from you and all Nairalander.. Wishing everybody a successful exam and Good result.

choiiiii

choiiiii na ur face be this

Swagalord18: it is correct

yep

Swagalord18: according to Dalton's law,
total pressure = sum of partial pressures
so 752(total pressure) = 32(water pressure) + x(oxygen pressure)
x = 752 - 32 = 722mmHg(oxygen pressure)
^p1V1/^T1 =
^p2V2/^T2 (gas equation)
p1 = 722 mmHg
V1 = 500 cm³
T1 = (30 + 273)K = 303K
p2 = s.p = 760 mmHg
V2 =
T2 = s.t = 273K

v2 = ^p1V1T2/_p2T1
= ^{722 x 500 x 273}/_{760 x 303}
=
426.78 cm³

P1 = 720 mmHg and not 722 mmHg......typographical error

[quote author=Ai-bi-ke]In d below reaction,.what is d value of x?Cr2O7^2- + 14H^+ + xe^-=2cr^3+ + 7H2O
pls waht I need most is aw u get dat value,...xo ur workings is all I need[/quote]balance the charge at both sides.....
Total no of charge in the RHS=> +14 + (-2)= +12
total no of charge in the LHS=> 2 *(+3)= +6
: . RHS must be equal to LHS
i.e +12 + 6e^- = +6
x=6
thus, we have the equation as:
Cr2O7^2- + 14H^+ + 6e^-=2cr^3+ + 7H2O

Swagalord18: [color=grey]+yawns+ ......and thats the reason why the magnification is always 1.0, ..it neither magnifies nor diminishes, ....the object distance is 10, so the image distance will be 10, ....
Magnification = ^10cm/_10cm = 1.0, ....its that simple[/color]

i agree with swagalord.......but the fact still remains that plane mirrors don't magnify...

More power to your elbow @ dr. Laz and all other gurus in da house.
Let quickly take our brush with these;

[quote author=Dr. Laz'Devitan]Dear sir...u are wrong......i saw so many errors that got u a bad landing![/quote]oh!! It was an error of the first order....never to make that again...i should have used H20 and H^+ for the balancing....a slap on ma face

aysuccess99: this looks like a further maths question, but I will do answer it.
solution
x=4t^4-3t^3
V=dx/dt=16t^3-9t^2
therefore, V is velocity, and it is 16t^3-9t^2
and acceleration=velocity/time
a=dv/dt
a=48t^2-18t
therefore, when t=3seconds, acceleration would be.
a=48(3)^2-18(3)
a=48(9)-18(3)
a=432-54
a=378m/s^2
therefore,:::::::: the acceleration after 3seconds is 378m/s^2
to the bosses and ogas in the thread, my answer is subjected to correction. Thanks.

correct

Find the acceleration after 3 seconds of a body moving in a straight line with this equation y=4t^4 - 3t^3

[quote author=Dr. Laz'Devitan]......Let me again pinch u all with a good chemistry question

Balance the following REDOX REACTIONS

1)[CLO(3)]^(-1) + Zn ---> Cl^(-1) + Zn^(+2)[/quote]i belive,you forgot to tell us the medium we should use....but i'll use acidic medium..
Cl03^-1 => Cl^- ( reduction)
zn => Zn^2+ (oxidation)
Cl03^-1 + 3H + 6e^- => Cl^- + 3OH
Zn => 3Zn^2+ + 2e^-
finally: Cl03^- + 3H^+ + 3Zn => Cl^- + 30H^- + 3Zn^2+

aysuccess99: Let's continue with the question and answer series. someone should answer this physics question:
1. The magnification of the image of an object placed in front of a convex mirror is 1/3. If the radius of curvature of the mirror is 24cm, what is the distance between the object and its image......
A8cmB16cmC24cmD32cm
2. when a yellow card is observed through a blue glass, the card would appear:
A. black B green Cred D white.
3. Three resistors with resistance 250n,500n,1kn are connected in series A 6v battery is connected to either end of the combination. Calculate the potential difference between the ends of the 250n resistor.
A.0.20vB 0.86v C1.71v D3.43v

waiting for correction

Kunlexic: 1.
usin pythagoras theorem:F2^2=13^2-5^2
F2^2=169-25
F2^2=144
F2=12
Ansa is C.12.0N

2.f=60Hz,/\=45cm=0.45m
v=/\f=0.45x60=27
the ansa is A.27m/s.

wat of if i predicted 54 m/s......just guessing.

[quote author=Ai-bi-ke]U can as well use dis as a shewing stick,.....The sides of a regular polygon are produced so that evry pair of exterior angle and interior angle is ratio 1:4. Calculate
a.the size of an exterior angle
b.number of sides of d polygon[/quote]it has been some time now i've been contemplating over this question since you posted it initially.......but within my own knowledge, i resulted into this:
let exterior angle be x and interior angle be 4x.......then x + 4x = 180.....
X=36 degree
thus,
1)size of exterior angle=36
2) 2n-4)90/n=144
n = 10
pls my answer is subject to any correction.....
