guys, i wish to contribute my own quota too by solvin some posted question frm ya all,bt i havent been able 2 reg up till today,av did coc d day ui reg started,right now im depress a little,anybody with useful info?

I advise that you go complain in person.it will be more effective .

Pls I tried to help my brother correct his mistake because he mistakenly placed his passport where he ought to place his signature but it is still not changing. Pls what can I do?

Please, i just printed my registration slip but my picture isn't showing in it.
what do i do now?

hi everyone.
its been a long time in here

Eben331:
DrBESTJC, u dnt answer questions nowadays, why?? You just dey view without commenting. Help me with my question.

Oh..so sorry for that Boss...
The thing is that something came up lately that gave me a very busy schedule and I was working to relieve myself from it.

I solve every single question posted on this thread. I post only the ones I am 100% sure about......and the ones solved and posted by other Bigger Boses here,I need not stress myself to post them again.

Now back to your question:

Eben331:
A Physics student standing on the edge of a cliff throws a stone vertically downward with an initial speed of 10m/s. The instant before the stone hits the ground below, it is travelling at a speed of 30m/s. If the physics student were to throw the rock horizontally outward from the cliff instead, with the same initial speed of 10m/s, what is the magnitude of the stone just before it hits the ground? (a) 10m/s (b) 20m/s (c) 30m/s (d) 40m/s. PLS SHOW UR WORKINGS!!

I have been ruminating over this question from the very first day you posted it.

But,my problem with the question is in the last sentence which says:
what is the magnitude of the stone just before it hits the ground?
Magnitude of the stone....as in what?
Is it magnitude of the Mass of the stone or Magnitude of the weight of the stone or Magnitude of the final Velocity of the stone ?

I think from the options given that the question should be :
What is the magnitude of the (Final Velocity of) the stone just before it hits the ground?

Please check well and reply....So that I can give you my final answer to your question.

Big Boss!!

Where have you been??....We've missed you here ooooo.....especially in English.

Abeg no leave us here again ooo....

follow the instruction in my previous post,

after do the changing proceed to printing of reg slip even if they refuse to change.

if your passport displays on your slip, that means you are good, but if not, you should keep trying through the week end and if its still the same till monday, I ll advice you mail/call or visit admission office.

Big Boss!!

Abeg no leave us here again ooo....

Who's boss ? una don start again

its preparation that kept me away from here ooo plus my faulty phone.

i missed you all too.

afoobabs Big boss abeg ooo I did C.O.I since 17 of last month and I can't lpgin . Please what can I do??

afoobabs:

hi everyone.

Boss, welcome back! We really need you here for English.

@DrBESTJC, ok, no problem...stop whinning me, who be boss?? I think you are right, the question is supposed to be 'what is the magnitude of the final velocity of the stone just before it hits the ground?' But that is how I dey see the question.

..This UI practice question nah and in d option m/s was there as d unit....I don't think u need anyone to tell u DAT it is the magnitude of d final velocity they were talking abt...U should also know DAT d body will av both horizontal component and vertical component of its final velocity has it hit the ground in the second motion... V =√ Vx² + Vy²....for the first case.... H = (V² - U²)/2g..
H = (30² -10²)/20 ...H= 40m
For second motion... D height is d same....ur Vx= 10ms-¹ DAT does not change throughout d motion....u can calculate ur Vy since u know your height......Vy= 0² + 2gh.no initial vertical velocity..Vy²=2gh...Vy²= 2× 10× 40 = 800m/s
V=√ Vy² + Vx²...Vy² =800
V = √ 10² + 800
V = √100 + 800
V = √ 900
V= 30m/s....

samuelizz:




Vy = final velocity of the vertical component of the velocity.
Uy = initial velocity of the vertical component
Ux = initial velocity of the horizontal component
Vx = final velocity of the horizontal component
when the body was thrown vertically downwards
(Vy)² = (Uy)² + 2gh.
30² = 10² + 2(10)h
20h = 800
h = 40m ( the height of the building )
Now, when the ball was thrown horizontally..
(Vy)² = (Uy)² + 2gh.
but Uy = 0 , since the ball was thrown horizontally.
(Vy)² = 2(10)(40)
(Vy)² = 800
Vy = √(800)ms-¹ (that is the final vertical component of the velocity )
But Ux = Vx (horizontal component is not affected by g)
The velocity it hits the ground V = √[(Vy)² + (Vx)²]
V = √[(√800)² + (10)²]
V = √(800 + 100)
V = √(900)
V = 30ms-¹

dis is d method i use Uv=Vv Uh=Vh 10=30 10=Vh Vh=30*10/10 Vh=30m/s dats d ansa cc eben331

im not in ib,but i have a final yr bro in ui,he even went to d admission office yesterday nd he was told again dat evri thing wil be rectified nextweek tue,he even said he met a guy,dt his sis wanna change frm oau 2 ui,nd d admin officer in charge of complains said she should go ahead.

Please I need Explanations to this:

Thanks boss. I have really forgotten dat dis question had been solved by oga samuelizz on page 60.

Thanks ma. I had forgotten dat dis question had already been solved by oga samuelizz on page 60.

Pls ,
Does anyone has UI's engineering group link ?

Thats was a very close call. Jamb might not have sent your details to UI. I learnt that it takes two to three weeks for JAMB to send COC/COI details.

If you av some other candidate that did C.O.I about the same time you did yours and are able to login now then you should worry and probably visit admission office. If not, you just have to wait and pray UI extends her PUTME reg.

Any UI DE MBBS aspirant should chat me up on whatsapp , let's get to know and share info

yes true talk @babs i did mine on the 16th of july.@Drzay dats d right info u nid now.just knw dat u aint d only one.

A) all their sons will be haemophilic
B) all their daughters will be haemophilic
C) all their daughters will be carriers
D) all their sons will be carriers

Okay. Lemme try:

First and foremost , sex linked characters are usually carried by the X chromosome in humans.
Now that we've established that, we know that males have Chromosome XY, while females have XX chromosome.


Haemophiliacs are usually denoted by 'hh' on their chromosomes;

Carriers of the hemophiliac gene are usually denoted by 'Hh' on their chromosomes;

While Non-carriers of the gene are usually denoted by 'HH'on their chromosomes.


Now, back to the question, it says that the man is haemophilic, Let's see how the man's Chromosomes will look like:
Bearing in mind that hemophilia is sex linked, it will only appear on the X chromosome :
So, the man's chromosomes will look like this:


X^h Y



For the woman,
The question states that she is not an hemophiliac and she doesn't carry the trait, so her chromosomes will look like this :

X^H X^H


Now that we have the chromosome set For the man and the woman let's use a punnet square to cross (In the diagram below) :

From what we have in the diagram, we see:

1. X^H X^h

2. X^H X^h

3. X^H Y

4. X^H Y


This means that:
I. Their daughters will be carriers of the hemophiliac gene

II. Their sons will not be hemophilic and will not carry the gene.

So, Option C Is Correct

This one that OAU is just losing accreditation anyhow, make their aspirants no change to UI oo. Make dem no inflate cut off for us oo

they won't.
if they change their institution to ui,it won't work out considering the fact that ui post utme will soon close
