I think it's B
Rule no 01 : The one of is a singular term and generally used to talk about a noun or a pronoun.

Rule no 02 : The noun or a pronoun used after the phrase “one of” is always in the plural form ( as we are talking of one person/place/thing out of many)

Rule no 03 : The helping verb will always be in the singular form, as the helping verb agrees with “one of” and not with the plural noun in the sentence.

This one dey hotoooo.......let the hot physicists here help out abeg...


The acceleration of a body which slides down freely on a smooth plane inclined at 60 degrees to the horizontal is.....
A: 5.00m/s^2
B: 7.50m/s^2
C: 8.66m/s^2
D: 10.00m/s^2


Explanations TO THE CORRECT ANSWER will be highly appreciated.

Hardebaryor:
Fe2O3 contains 2 atoms of the element iron per molecule.
Iron ore contains only 70% of pure Fe2O3.
Fe2O3 will produce 2Fe
i.e [2(56)+3(16)]g of Fe2O3 will produce 2(56)g of Fe

160g of Fe2O3 will produce 112g of Fe

160kg will produce 112kg of Fe

80kg will produce (112×80/160)kg of Fe
80kg will produce 56kg of Fe

Now, 70% of 56kg=39.2kg

I need explanations to the RIGHT answer.

fashmann:
I will be bringing some of the things I promised very soon

But before that, let's see who gets this question





Cl2+O3---->>>ClO +O2


ClO ----->>>Cl2+O2


The catalyst of the above reaction is?

Pes13:
As we proceed, I will be unravelling the tricks I learnt myself in calc in PH, sine of any angle, dividing standard form without the use of calculator, picking correct option when you do not really know the answer and lot more.



No matter how you study, you cannot know all Questions , but if you know your way , you can get all questions


Everyone has a trick that they discover, by the time our bosses start dropping their tricks in various sunject, I am sure, it will really add to our stature.

Xo we only need to take them serious.

Drbabalola:
Lols! You mean scoring 90% in utme english? It's practically impossible, unless you want to be reading only use of english at the expense of other subjects. My brother, the more you understand the 'invisible teacher', the more confused you'll be when you get to utme hall; though your construction will improve significantly. Read the book normally, read your novels and newspapers as well to learn tactics of passing english exams. God bless you.

@ Pes13

Sir,I need the names of the authors of LAMLAD CHEMISTRY and LAMLAD PHYSICS.The books are scarce in my area and any bookshop I visited keeps asking me of the author's names to be able to identify it.

Also,please don't forget the questions I asked you in the other thread about studying smart and secrete to scoring 300 + in JAMB and 95 + in UI PostUME.That is where we need to start because JAMB is already 3 months away,so that we don't waste our time studying amiss.

Thanks and God bless you for the wonderful work you do here.

I can see all the aspirants here scoring 300 + in JAMB and 90 + in UI PostUME.....!!!

Just 'one like' for those entering UI with me next year......
