VERTEX1:
HI All,
I've been following the thread starting from the day it's creation.
but due to insufficient resources I couldn't chat then,
I must say this is the best thread for now on nairaland. Have learnt a lot already. Donpre very familar name, Optimist Good job guys, God will actually see us through , its our year!!!

seriously? how very familiar?

castrokiller:
See question o... I go slap person o..
Which of the following statements about protoplasm of a cell is not correct? It
A. irony B. euphemism C. none of the above D. meterphor.
Explain your answer

C... reason: Biology doesn't have relations with literature terms

Optimist1998:
Far away jos

Unijos then?

Optimist1998:
Seems they compensated the otherwise dumb move by reducing the number of questions

Not too shabby if you ask me

Yea, just seeing that... not bad at all. Infact I think 2 hours would be too much

castrokiller:
unizik

funny enough, we almost ended up in the same school. Last minute change of heart tilted me the path of uniport

wish ya success bro

@Optimist1998... which destination you headed?

Nuel25846:
how abt uniuyo... is choosing uniuyo a good idea?? even if it is not in my catchment

Sure! number of aspirants is low, which increases your chances.

Have you guys seen this?

This is crazy!... so a mandatory use of keyboard keys wasn't bad enough, now this.

They are giving stup!d excuses while forgetting that a reduced time would lead to increased pressure, tension and anxiety, hence another inglorious year of mass failure

Well all I can do now is laugh engineering aspirants... maths, phy, chem and English under 2 hours? it sucks to be them right now

GrandFinale2017:
an institution that'll solely use UTME scores as her sole criteria for admission and also favors my state as catchment consideration. E.g uniben.

How about you?

Same idea buh uniport.... I'm just hoping they stick to last year's method

Nuel25846:
I keep getting most of the questions wrong cos I mis-use the formulas.. this happens when am under tension or pressure.... i need HELP!!!!
how can i solve questions correctly under tension or pressure?.... Donpre and Optimist1998

Its simple(maybe not so simple). Add more tension, and solve more past questions till your brain gets use to the pressure. Or you can practice being 'detached'(i.e emotionless) throughout the exercise.


sadly, neither of them is easy

GrandFinale2017:
no.. I had C6 parallel and twas rejected at the University of Ibadan.. They adopted o level grades which favoured those with A's and B's

since you're not rewriting, then you probably choosing another uni then... Which do you have in mind?

Why not keep both methods and let the candidates decide which they prefer.

Now someone will be solving physics and also be bothered about not a mistake and pressing S.... God the Stress!!!!

GrandFinale2017:
unfortunate too. O level grading ish knocked me off. Pray this year culminates me to success

Sorry about that... I do hope the year brings us all success.
@O'level, That means you're rewriting ryt?

GrandFinale2017:
same last year's utme thread.
What happened?

wasn't good enough I guess... Wah bout u? undergraduate yet?

Optimist1998:
Ok I'll wait till you revise it.
That should clear up the confusion.

Sadly my textbook isn't anywhere close, but then I realize you are right. A capacitor can store charges hence reducing sparks created by the inductor.... My bad!

GrandFinale2017:
guy I remember you from last year's thread...
Are you writing this shiit again?

Haba! remember me. Damn! I'm now a popular jambite(Lol!)

Anyway, yea I'm writing again... and which thread exactly do you remember me from?

castrokiller:
What are u applying for... Mine is med%surg

Same bro... which uni?

I'm also totally against the WhatsApp idea, the inefficiency of WhatsApp groups cannot be overemphasized

Optimist1998:
Kk
For that of capacitors.

I don't understand, I thought capacitors store charge which it used by inductors to produce sparks. Now you're saying, capacitors reduce the number of charges and brings about less or no sparks

Maybe I gotta go revise that topic

Optimist1998:
I. Mass
II. Density
III. Temperature
IV. Nature of substance
which of the above affect diffusion?

A. I and II only
B. I,II and IV only
C. II, III and IV only
D. I, II, III and IV

Past question thinks C is the answer
I think D is the answer
What do you think is the answer?

Since density is directly dependent on mass and volume, C is definitely wrong... I'd go with D

Optimist1998:
I really do hope it's a typo

Where you able to complete your jamb reg today?

yea I was

Optimist1998:

Still Pressure
A rectangular tank contains water to a depth of 2m, if the base is 4m x 3m, calculate the force on the base (Density of water = 10 3 kgm -3 , g = 10ms -2 )
A. 1.4 x 10 2 N
B. 24 x 10 4 N
C. 2.0 x 10 4 N
D. 1.7 x 10 3 N

B

Nuel25846:
Tension A 1000kg elevator is descending vertically
with an acceleration of 1.0ms -2 , if the
acceleration due to gravity is 10ms -2 ,
the tension in the suspending cable is
A. 1.0N
B. 10.0N C. 9000.0N
D. 11 000N
1000kg*1.0ms+1000kg*10ms=11000N ans D

which formula did you use?

Optimist1998:
Which of the following is true of sounds?
A. sound travels faster in air at 20 o C than at 30 o C
B. the frequency of a given sound wave changes when it crosses the boundary seperating two media
C. the wavelength of a given sound wave in air decreases as the temperature increases
D. sound waves cannot be reflected

Please lets discuss this......
Why is C the answer, I don't agree with any of the options above. Maybe I'm missing something.

I think there isn't a correct option too

@Option C, Since velocity increases as temperature increases, and frequency remains constant, then wavelength should also increase and not decrease... could be a typo or a mistake. I'll Google search just to be sure

Optimist1998:
I just recently discovered that the collision of molecules with each other is not perfectly elastic as some energy is transferred to the next molecule causing that molecule to move (Kinetic energy). Sadly our textbooks didn't stress this point...........

ermmm... I thought all molecules in gaseous state are already in continual motion due to kinetic energy already acquired

it could be plausible that molecules that collided with the container lose their kinetic energy and have to regain it from another molecule

Optimist1998:
Physics

-The resultant force of a couple is ………?
A. Infinity
B. Zero
C. One
D. Half

B

- Capacitors are used in the induction coil to
A. control circuits
B. prevent distortion of electric fields
C. prevent electric sparks
D. dissipate energy

I'd go with D

- If the mechanical advantage of a machine is 4. What is its ratio for LOAD to EFFORT?
A. 4:01
B. 1:04
C. 5:01
D. 2:01
_

Most Def A

-If a projectile has maximum range of 36m, find the speed of projection (Take g = 9.8m/s 2 )
A. 27m/s 2
B. 2m/s 2
C. 4m/s 2
D. 7m/s 2

I'm assuming there isn't an angle. using the formula for range, there wasn't a correct option but using the formula for maximum height, A would be correct

Are you sure the question is correct?... and the S.I unit of the answers is also wrong

Nuel25846:
let's say the answer is B....as for the E when molecule of gases hit the vessel in which they are contain kinetic energy is is not conserved,the energy will convert to another form of energy.....so the typo is not in the question but the answer.

"E. The collisions of molecules with each other are inelastic"

You should pay attention to details. it clearly stated collision with each other.

The question is correct, just the "inelastic" typo

Xup pals, I was expecting to meet questions. kinda disappointed

As for my absence, I was busying entering queues after queues unto jamb reg wahala. Still didn't do my reg

@"he is a genius" you kidding ryt?. I'm averagely intelligent jor

Nuel25846:
. Charls's law is V=P not V=T

you mean Boyle's law which is actually V=k/p or PV=K

Nuel25846:
I got the question from JAMB past question and the answer is 'D'.

the id!ots that answer jamb past questions tho... How can Charle's law be incorrect?

Nuel25846:
Which of the following statements is
NOT correct? A. The average kinetic energy of a gas is directly proportional to its
temperature B. At constant tempearture, the volume of a gas increases as the
pressure increases C. The pressure of a gas is inversely proportional to its volume D. The temperature of a gas is directly proportional to its volume E. The collisions of molecules with each other are inelastic

B & E are both incorrect... unless in option E you mean gas molecules and the 'inelastic' was a typo

An organism that exhibits viviparity is
a.termite b.Pisces c.Tse-tse fly d.Aphid

Hemoglobin is a/an
a. Hormone b.Enzyme c.Protein d.lipid

vicstiqs95:
arachinada dnt hv antennas . nt all classes under anthropoda has antenna. insecta is correct.

The only class under arthropoda without antenna is arachnida.. crustaceans, myriapoda and insecta all posses antenna.

antenna can be said to be a feature of arthropoda instead of just insecta.
