Optimist1998:
Wow your method is even better.
I calculated the area of the two triangles within the 2nd and 5th second then summed them up.

Optimist1998....something abt u got my attention....is there any way we can talk privately??

Optimist1998:

I calculated the area of the two triangles within the 2nd and 5th second then summed them up.

either way I still got it wrong.

Optimist1998:

Close but not correct
How did you get 2?

I have seen my mistake....it suppose to be 3*1/2 and I did 4*1/2..........displacement=average velocity * time.

Optimist1998:
Basic velocity Time graph from SS1
Calculate the displacement between t = 2s and t = 5s of an object that moves along an axis and has the speed characterized below.

The answer is D.d=2m

yeah it isn't that sensitive bro, and it's just the best cos I can last as long as I want and enjoy any pussy like I desire..

maybe I was circumcised properly.

femolala001:

Pls hw did u register? U registered tru bank or where? Pls reply my msg??

I did my registration at one of the approved cyber cafe,it is located in surulere.....Knowledge ware technologies,87,Itire road,Ojuelegba,Lagos.

My dick cap is very,very sensitive....if it enters into anything soft like a mouth.....I will just enter into another realm....maybe ur dick cap ain't sensitive like that.

Water does not drop through an open umbrella of silk materials unless the inside of the umbrella is touched. This is due to A. capilarity B. osmotic pressure C. viscosity D. surface tension

If an object just begins to slide on a surface inclined at 30o to the horizontal,the coefficient of friction is

A. √3
B. √3/2
C. 1/√2
D. 1/√3

The property which makes alcohol
soluble in water is the A. boiling point B. hydrogen bonding C. ionic character D. covalent nature

The substance least considered as a
source of environmental pollution is A. Lead compounds B. Organophosphorous compounds C. Silicate minerals D. Uranium

Three drops of a 1.0 mol dm-3 solution of NaOH are added to 20 cm3 of a solution of pH 8.4. The pH of the
resulting solution will be A. Close to that of pure water B. Unaltered C. Greater than 8.4 D. Less than 8.4

pls kindly fold this list.... and shove it up ur ass.

I can totally relate,I've worked in a hotel before...but this ur story is so real... like i was there with u... but what kind of blow did the guy give u?

If the load at the end of a sonometer wire is immersed in a bucket of water, the original fundamental frequency of the wire could be restored by A. decrease the length of the wire B. increasing the length of the wire C. increasing the mass per unit length of the wire D. changing the temperature of the wire I would go with A.

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

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 slove questions correctly under tension or pressure?.... Donpre and Optimist1998

Donpre:
which formula did you use?

Mass*Acceleration due to gravity+mass*Acceleration

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

Optimist1998:
parallelogram law....That's even better.
I wanted to create a mental picture before applying laws. From the rope analogy, you'll definitely feel more pain when your arms are wide apart. Why? You're spreading your arms at an angle.

But when your arms are straight up, just your weight is pulling you down. Now this cancels out option C.

What's next? Now that we know the answer is between A and B. You can now apply any law you wish to apply to find out which case has the highest tension.


Either ways Tension would be greatest in Y...option B

Yeah, true.....pls more questions.

All these questions are so confusing....

Optimist1998:

Try to imagine this; you're holding a rope like the one below with both hands . Lets say it's tied to two tall buildings and you're stuck on top. What position would be more comfortable;
>>Hold the rope with your arms straight up or
>>Spread your arms
(piture attached)




Ps: by comfortable I mean less strain/pain on your muscles/hand

I kinda used the parallelogram law of vector.

Optimist1998. The fig above shows three different ways of hanging a heavy picture from a hook. the tension in the string will be A. Greatest in X B. Greatest in Y C. Greatest in Z D. Same in each one.....the answer should be C.

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 The answer is A.4.01....MA=Load/Effort.

Where is Donpre?? I like the guy...he is a genius.

Hydration of ions in solution is
associated with A. absorption of heat B. reduction of heat C. conduction of heat D. liberation of heat

Donpre:

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

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.

Donpre:

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

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

Donpre:

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

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