Hahaha.. Our teacher wasn't that "good" (we would correct him in class. I remember when he marked "rubbish" in my exam [Bio] I had to report him to his close friend (another teacher) He was taking us Bio and Chem then. Because of his poor teaching I'm not that good in Chem (In fact, I can say most what of I know in Chem now is "self-learned"). Biology is easier to understand than any other sub (to me sha). In class then, we would prefer Bio lectures to any other.

I don't even take Bio that serious in my current Jamb preparation. My main concern is how to cope with those two BIG guys; Phy and Chem (Physics especially)

wait truf b told,u n Holamarcy dey confuse me,which one of u is presently at OAU studying agric n wishes to apply for med at UI

lolxxxx na really BIG guys,to me eng is d biggest guy,don't b scared cos of dose 1980+ physics,it wil b much simpler cos dose years wen JAMB likes wrecking pple is far beyond us.Compare d 2000+ n 1978-2000 past questions n u wil c wat am tokin abt,don't develop phobia for JAMB,ok?

Hehehe you fell in love with the gate.

By God's grace, I shall meet you there

which course did u apply for?

Spam bot let me off the hook. Ban expired!

Boss PrOton, I'm back!

@Estijaz, pls forward ur future posts to this username..im bout to delete the other account.

wat was ur initial username

Holamarncy:
nope m nt

hmmm datx surprising u r too gud to just b an aspirant

Bhuumhite:
what course are u in for?

mbbs,u?

felixyiga:
in idia some blocks called flats are 3 per room while odas are 6 and Awo is 4 per room

I just hope I get into Awo hall,itx a very nice hall from d pix av seen

MockinJay40:
I don't even know why...i guess Im attracted to UI than any Deltan University.

Why did you abandoned all our univs n choose UI sef?

Are u from Ossissa too?

#NdokwaEastLGA

Nope from Oghara Ethiope West LGA,,cos itx beta dan d ones here na p.s I fell in love wit d sch gate d moment i saw it

Pr0ton:
It is not stated that way.

hmmm k

Pr0ton:
Almost everyone I meet likes Biology, you are exceptional. What's about it that you don't like?

d diagrams n itx just too complex for my brain to comprehend.contrary to wat u said,everyone in my school hates bio maybe becos d man teaching u is a sadist sha,dont really knw

Pr0ton:
I should also ask why you used all the 100% when only 5% was give off as light.

If you read the question closely you'll see that its context is about non-luminous heat produced.

wat I see weneva i read d que is dat only question 1 is abt d non-luminous energy y d rest r talking abt both

Pr0ton:
It's annoyingly interesting. I offered it late in high school (ss3)

lol@choice of adverb.I love Fmath so much dat I can fail math but no fmath,don't knw y n Math is suppose to b simpler.As for biology,I dread dat subject so much,am not gud at it atall

felixyiga:
it depends 3-6 as regards the hall/hostel

how many in awolowo's hall n Idia's hall?Thanx in adv

I was about objecting when I forced myself to recheck the past question I thought I saw simple present (3rd person singular)/ present perfect, and then I realized I had, in the first place, checked wrongly...

It is actually simple present (3rd person plural)/ present perfect i.e "sell/has" (Jamb past question, page 146, no. 72)

Forgive my mistake Cassyrooy, Preciousjoz, Estijaz, DrHost, Holamarncy, Bhuumhite, Pes13, Dsurgeon and co.

Thanks for the correction

dont mention.English is harder dan all subjects sha,no1 can just b perfect in it

Pr0ton:
Futher what Mehnnnn

don't u like it or didn't u offer it in sec sch?

Pr0ton:
True that the unit of heat is Joules. But if you were very conversant with the topics: Energy and Power; and Cost of Electrical Energy, you would notice that "Joule is too small as a unit for dealing with the energy demands of households and commercial ventures", so PHCN doesn't use Joule. They use a large unit instead, i.e the Kilowatt-hour (KWh)



Your calculation is based on the SI unit Joule. Mine is KWh. If I converted mine to Joule I would get the same answer as the above.



Error. You should use 95% which caused your no.3 error.

Gimme one reason y u had to use 95%,datx d amount of non-luminous energy not d whole energy produced by d bulb na.Wel nobody is all dat perfect,I myt b rong,who knows

Pes13:
I'm confused, but in invisible teacher, it was stated that who will refer to the noun or pronoun that comes before it and that noun or pronoun must become subject

example they used is this
One of the girls who________impregnated_________died (a) was/have (b) were /have (c) was/has (d) were /has

Option d was choosen

don't b confused,wat u read is d tru tin,let dem argue for a while,dey will c reasons wit us lata

Pr0ton:
Exactly....

hmmm datx wat u guys fail to understand n I don't knw hw I can make u guys c reasons wit me,wel letx forget abt it all together

Bhuumhite:
electrical energy is measured in KWh

dey r talking abt heat energy n besides datx hw PHCN measures electrical energy,datx not d S.I unit

DrHost:
the first thing is pressure decreases with height at d height of 80 d pressure is 760 to get d rate of decrease divide 760 with 80 u have 9.5 i.e for each km rise d pressure drop by 9.5 so when a dis of 20km is covered d pressure as reduce by 9.5 * 20 which gives 190 so to get d pressure at 20km we deduct d lost pressure from the total pressure 760~ 190 u get 570``` Hope am right

yeah absolutely ryt,kudos

I got banned by Anti-spam bot for posting the answer..maybe it couldn't figure out the post

I had to embed it on the pic below.

@Estijaz, yeah I'm from Delta state too. (Ossissa)

#myNewAcctTill2maro

wow datx nice,meeting a fellow deltan in a land dominated by d yorubas,I think we will get along real fine but I must y did u abandon all our univs n choose UI na

Holamarncy:
..
both av interval of 760 and 80
760mmHg =80km

1km=760/80 = 9.5
so for every 1km increase z 9.5mmHg decrease.
so 20km increase Z 20*9.5= 190mmHg decrease
soooooo
760-190= B

wait remind me again,aren't u already a fresher?

Abeg dis one na for science aspirants only abeg make d gurus dem nor murder d question for me.here it comes

the height at which the atmosphere ceases to exist is about 80km.If the atmospheric pressure in the ground level is 760mmHg,the pressure at a height 20km above the ground level is (a) 380mmHg (b) 570mmHg (c) 190mmHg (d) 180mmHg

Na wa o! No hot chicks for this thread sef.. Decided to frolick down the 34pages and I am utterly disapointed. Which kind School be this Ibadan sef Thread 's just dominated by scary dudes whose mental faculties 've been totally fried by formulars and chemical equat_ns..

Mo gbé

Them don tell me before say this U.I dey boring i no believe..

I was hoping 4 a wonderful campus experience

....guess i'm in 4 a rude awakening!!!

Where's this bros? @ geedot ...i greet u o!
Tell me its not that terrible in sch.

Cassyrooy, i see you!

But seriously ehn UI na boring sch but we nor complain,leave am for us biko

I was referring to you d boss doing this and d ans for proton que is were

hmmm I c,but am not a boss oo just a humble learner at Jesus' feet,we all r except d muslims ofcourse

Even d boss is solving d que for boys..... Proton since those arrested then it were ...

I don't get

Pr0ton:
Anyone on Physics?

Of the energy expended in an electric light bulb, only 5% is given off as light. A typical 40-watt bulb costs 60 Kobo and has a life of 1 000 hours.

1. How much non-luminous heat is developed in the lamp?

2. If PHCN charges 6 Kobo per unit, what is the cost of operating the lamp?

3. What fraction of the cost of operation is the cost of the lamp?

1)Heat is a form of energy n d SI unit for energy is joule na,y r all ur answers in kwh?It is d unit PHCN uses.To me d solution is this

w=pt = 95/100[40 * (1000*60*60)]=1.368*10^8J

2)PHCN total power consumed weda it was converted or not.So we use d entire 100%
cost=(40/1000)* 1000 *6=#2.4

3)Dis is d simplest of all
fraction =60k/240k=1/4

hmmm but nothing is hard nor is there anything that simple..... When u create d passion u find things simple

not necessarily but itx somewhat tru
