lolzzz u Ehn,neva knew MDCN will b d one to mark our mb exams oo,,av been kul,u?

miss, how is prep for skul..... @

horpeyemmi66:
@PrOton, o su mi ooo

U know Buhari story you know our story

Holamarncy:
lol ..me and sleep no dey lydown open teeth ..we no friends....

you guys dey scare person ooooo...... What was your last year jamb score

evening guys , someone ones said here tha he has the ui post utme past que..... Pls let here from you if you are the one

Tholuwaniey:
What about dentistry??

dentistry is in college of medicine

hollamancy

Na wa o! I just called Chams City Abuja branch and was told directly that;

"JAMB 2015/16 reprinting has been postponed until further notice, but you can call back within the week to know about developments".

This i think might be after waec, the development discourage potential readers, thereby encouraging sporadic parambulating(e.g Pr0ton), which is not ideal for students.

so this one of the improvemnt u saw in jamb I guess .......... Estijaz am waiting for your solution on horpheyemi half math que, anything from u is always correct

holluwahdharmie:
am also aspiring physiology 2015 and MBBS 2016

may I join ? Are you planning to cross or write 2016 JAMb ?

horpeyemmi66:
, shoo Tobi you wicked oo. So Whales2020 go ©hop am abi?. Okay am awaiting your answer @tobillionaire twisted the question to get humour outta it, show me w@ you gat, Yimu.

u mean que 3 and 4 am just leaving church

whales2020:
To me,ocen of unknown;land of no return!!!

naso bro

I cannot say specifically your score now, am waiting for Proton and others @ Estijaz, Dsurgeon, Sir XavierG, FunkySilver, SegunFlames, Kumpharm, Pes13,Bhuumite, Professor1234 et al. And Tobiloba work on the 3 and 4, Check 1 and 2 again. If Jonathan rows his boat North-East while the river is flowing east, under normal circumstances what will happen to him... Putting aside sentiments stemming from Physics?

he would be heading to atlantic ocean

sorry didnt see d ratio in d front of velocity in que 1 so weight and momentum i.e c and 2 south west

From mancity newcastle game .......1 d 2 d nt sure navigation is my weakest give me time for 3 and 4 5 a 6e 7 b 8 a 9 d 10 b 11 a 12 c

horpeyemmi66:
How you go feel if you jam two or three of my questions for your exam?

sweet ques will try to get time 2 , 3 que requires calc and am nt with it...... How is ur side bro #saibuhari

cassyrooy:
They've improved so are we gonna sit up and improve too. But WURUWURU? Hmmm!

what improvement sir ? Jamb scores are no longer a real reflection of candidates performance

Bhuumhite:
which tym estijaz bcome ur prop?

since when she stopped commenting here or na sin ?......... Pes I respect you sir..... @whales are u doing what am doing ?

Where is prof ? #bringbankmyestijaz

[quote author=Pes13 post=30948958)almost 3000 candidates scored above 300 in 2011, it reduced drastically to 3 candidates in 2012 and 10 candidates in 2013, xo dey are telling me less dan 10 candidates outa over 1 million is capable of scoring 75% in dere exam.

I hail jamb wuruwuru to d answer.[/quote]jamb has lost her credibility....... I salute u oooo need to knw u

Is this the whales that I know ?

Holamarncy:
#scratching head#haha...

boss how jacking ?..... @ proton talk to oneself na selfie God....... Everything go to accreditated centres am guessing result checking go to accrd centre, admission status go to accred centre.... Dibu and his propaganda have lost touch with reality cuz they even know the examination date and time can change over night how do u xpect us to keep abreast with this their incosistencies when u cant check on ur own and this centres are too far and the cost is unbearable to be handling on daily bases .......what do u guys think

Pr0ton:
Lol. When last did I pray sef

hmmmm it Good to do

dara319:
Bin followin in d ghost mode all along,..lolzz...buh am done wit dat...hello...peepz...

wellcome ma

lolzz u n am nor really get work,I hate korea movies more dan Abacha,u know wat I mean

Going bk to d problems,question 2 ansa is 4,8,16 but u made a mistake, u rote 'there' instead of 'three'

question 1 is incomplete,gimme d value of sinZ n I can finally give u d ansa

question 3 is quite tricky,I got 3 ansas after further simplication,ur textbook myt give d ansa in any of dese forms but all r correct anyway
1/{√[(1+x)/(1-x)](1-x)^2} OR 1/√[(1-x)^3*(1+x)] OR 1/[(1-x)√(1-x2)]

I only hope u understand d jargons I gave as number 3 ansas but wait 1st o,JAMB dor get Fmath as e own subject?

#cant upload d working cos itx just too long n complex#

I am suspecting you guys we dey murder math and it bro for this thread..,. U look like the ogbanjes tht killed Yaradua....... I dey envy you

Pr0ton:
Everyone is battling Physics today. And yeah, the formula can extend to other calculations not directly under Power. It's always interesting when formular links to other calculations but very annoying when it turns out to be almost impossible to figure out. I would advise you get used to those power formulars. They are really helpful; they would ease your stress.

Power = IV
" " = I²R
" " = V² / R

But then I'm confused with the introduction of sin and cos to calculations involving power. What topic can I find a typical calculation of that?

that not whaat I meant.... I was using power as an example of interrelation of physics topics which will be bogus to cram..... My sin cos was referring to ques on momentum, triangle of forces, force and etc..... And where tan son cos is use under circuit power that can b found R L circuit , capacitor circuit impedance..,,.. And e.t.c

Professor1234:
av seen it lol

hmmm oga..... Dat one na first class cheating @proton I think one dont appreciate his or her knowledge of phy until we find relationship btw d topics....... Imagine thinking of cramming d dIff formulars of power from d.e to a.c, machine, heat and d rest it hard but imagine co relating it...... D confusing for me is where to use sin or cos atimes I feel confuse

I saw a Francistony comment it not d one of last year thread or is he ?

V.R of an incline plane 1/sinΘ or the apparent distance covered / actual dist cover i.e 400/3 133.3 or using 1/sinΘ gives same

Goodmoring and happy new week ahead..........

hey guys,try dis one

An air column 10cm in length is trapped into the sealed end of a capillary tube by a 15cm column of mercury with the tube held vertically.On inverting the tube,the air column becomes 15cm long. What us the atmospheric pressure during the experiment(a)76cm (b)75cm (c) 60cm (d) 70cm

A vehicle of mass m is driven by an engine of power P from rest.Find the minimum time it will take to acquire a speed v.(a)mv2/p (b) mv2/2p (c) mv/p (d)mv/2p

dis look like oau pst que.... I will go for B B
