Can Neco results be released before August 20 please to meet Unilorin deadline?

when will Neco results be released please? We were asked to upload our results on or before August 20 and I'm really counting on Neco

08185078180

it's out and I've checked mine!

Ui oo...don't kill someone with hypertension now...is it until we start using hypertensive drugs before you will release our results?
#day 5#

can it still be today?

when will these results be released now??

pls, add me to any whatsapp group available 08185078180

where are the science aspirants that did today..? how was it?

Eben331:
14/9.8 will give 1.4 and nt 1.6 Check again.

yeah, you are right
t is 1.4 sec
v equals u+at which is 14+(9.8*1.4) which gives 27.7m/s
will still go for C

Eben331:
Pls bosses in the house, help me with this question: A ball is thrown vertically downward with an initial velocity of 14m/s. Calculate the final velocity. g=9.8m/s^2 (a) 36m/s (b) 38m/s (c) 30m/s (d) 40m/s PLS SHOW YOUR WORKINGS!

answer is C, I think
the question is a bit tricky, U isn't equal to zero, from d question, it's clearly stated, g is positive. I guess
to get t, it will be U/g, which means
14/9.8 which gives 1.6secs
so, final velocity (v) equals U+at, which means
V equals 14+(9.8*1.6), which gives 29.6m/s, approximately 30m/s, which is B.

pabostt:


Don't be confused

1/f = 1/u + 1/v

However, in calculation the value of v is negativeand the value of F is negative because most images formed in a concave lens always give virtual, erect, and diminished image wherever the object is placed.

I prepared a free preparatory physics guide in pdf for students who want to download https://servantboy.com/category/physics-for-a-level-&-utme/

we are saying d same thing Sir, since V will eventually turns out to be negative, since it is diverging
so, it is safer to represent it directly with d negative notation from d formula to prevent time wasting

DrBESTJC:
Please bosses here...

What is the lens formula for a concave or diverging lens ? ...Two textbooks I have are saying different things and I am confused..

1/u-1/v equals 1/f
Since v is negative, I guess

boyejo123:

I don't really get this sir where did you get 20 for object

it was a mistake I mean 120, not 20 since we said v equals u and v is 120cm, therefore u also equals 120cm so, 1/120+1/120 equals 1/f therefore, 2/120 is 1/f f equals 120/2, which is 60cm

odumzy:
Please I need the PDF of
chemistry past question for ui

that's it
click on it to download it,ma

Eben331:
An object gives a real image, magnified four times at 120cm from the second principal focus. Find the focal length of the lens (a) 30cm (b) 40cm (c) 60cm (d) 80cm PLS SHOW UR WORKINGS!!

I got 60cm(c)...
for the image to be at 2F, that mean the object is also from d extreme 2F1.
therefore U equals V
1/v+1/u equals 1/F
I/120+1/120 equals 1/F
2/120 equals 1/F
therefore, F equals 120/2
which is 60cm
I think the magnification is just there to cause confusion or so
I'm open to correction, bosses in the house

Bigboy289:
Argon is used in gas-filled electric bulbs because it : A.is light B.gives coloured light C.prolongs the life of the filament D.catalyzes the burning of the filament ??

[C] It prolongs the life of the filament, since it is inert and it's not easily oxidized.. I think

Someone help has re-uploading of O'level ended on Ui portal?

Eben331:
That is why we humans are infallible. We are all here to learn. It is better we make those mistakes now than in the exam hall.

yeah boss! only God is perfect
can I have your Number, please?

Bigboy289:
D

yeah you are right it is flooding as a result of constant climatic changes noted boss

freshsteph:



C

please explain boss
thought it's air pollution
I wanna learn, sir
I thought global warming involves d release of poisonous gases like co2, so2, CFC into d atmosphere
and some of these gases reduces d level of ozone in d atmosphere, which help to absorb and reduce d UV rays reaching s earth, but since it has now been reduced, the amount of UV reaching d earth will increase..

Bigboy289:
what is the decrease in volume of air when pyrogallol is shaken with 30.00cm3 of air.
A.0.63cm3 .B.0.06cm3 .C.15.00cm3 .D.6.30cm3

Alkaline pyrogallol is used to remove oxygen from air
since d composition of air is 21%
therefore:
21/100*30 equals 6.30cm3

Gracy3535:
But it causes flooding

not really..Global warming is as a result of d release of poisonous gases into d atmosphere, which pollute d air or so.

please somebody should help me out what weight of HCL is present in 155ml of a 0.540 solution?? thanks

155*0.540*36.5/1000 gives 3.055g
please, I'm open to corrections

[quote author=freshsteph post=70734531]






30.5505g[/quote,)

I calculated it as well
got 3.06g
u might recheck it
