FIGHTING

I will get bk to u on dis,lemme go n sort d questions out.
besides do u love korean movies?

Pr0ton:
Estijaz where are you?

lol,I dey here o,fmath dey find me?

Pr0ton:
Hoho. Now I get. That's why I said I hate Physics So many things I learnt in Jan/early Feb, but due to their complication I've forgotten majority of them. I don't think I'll ever cover the whole Physics syllabus before Jamb, as I'll still take some time to revise those I've forgotten. I just hate Physics. Too broad and tedious to enjoy life studying it. But it happens to be a fate I've got to accept however. It's a must I face it. I have no choice. Who brought Physics sef?!

lolzz,e nor reach to ask but I still prefer am to eng n bio sha

tobillionaire:
. Yea

no wonder math is ur best subj,I wish u luck o in d jamb n pume

hey guys! happy sunday. there has been some contradictory information in this thread. whats is real date for slip reprinting. @ preton @cassyrooy @ estijaz etc

I av no idea but I will find out for u real soon

tobillionaire:
No... Buh it doesnt matter, i cn count on u as ma maths tutor in school

hmmm wat r u aspirin for den?Lol,too bad cos I wud av lose all my math knowledge wen zoology stats clocking my brain but don't worry u wil find very gud tutors,dose dat r beta dan in abundance at UI

tobillionaire:
so on point... Dis babe na ogbanje o

lolxxxx,r u a mbbs aspirant?

mattdasalt:
Yeah,you're right.

hmmmm *heaves a sigh of relief*
wat r u aspirin for,engr?

tobillionaire:
A circle with radius 5cm has it's radius increasing at the rate of 0.2cm/s . What is the corresponding increase in the area ?

dr/dt=0.2cm/s
r=5cm
A=πr2
dA/dr=2πr
dA/dt=dA/dr * dr/dt
dA/dt=2πr * 0.2
dA/dt=2π * 5 * 0.2
dA/dt= 2πcm2/s
dA/dt= 2*22/7=6.284cm2/s

therefore the rate of increase in the area is 6.284cm2/s.
If d tym was stated b4,u can calculate a new area but itx not so datx as far as d solution can go

mattdasalt:
(maths). X-2 is a factor of 2x^3+ax^2+bx-2 and when
the expression bounded by x+3 the remainder is
-50.find a and b and the remaining
factors

a=-1,b=-5,remaining factors=(x+1) and (2x+1)

Please who knows if d Egbegohon scholarship scheme is authentic cos am afraid it myt b scam seeing dat dey said we should apply wit #1000 n dat dey wil b no written exam just oral interview.Please any past beneficiary of d scheme should please say so dat I will not b deceived by scam.Tanks for ur future assistance.

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

(2) Power=p,mass =m, speed =v,time =?
p=(Ma * d)/t
p =(mv/t) * d/t
p =(mv/t) * v
p= mv2/t
t = mv2/p

(1) p =?,x=15cm,y1=10cm,y2=15cm
(p+x)y1 = (p-x)y2
(p + 15 )10 = (p-15)15
10p + 150 = 15p - 225
5p = 375
p = 75cm

Dsurgeon:
hw fr d physics questions wen u post?

Hmm sorry I forgot to post d ansas
(1)75cm (2) mv2/p

Awo might not be good for you, especially in 200 level.pray for Idia or queens

Hmmm okk I surely wil

nice info but itx for 2014 not 2015
