A boy observes a cricket ball move up and down past a window 5m high. If the total time of the ball in sight is 3s. Find the height above the window that the ball rises. PLS SHOW YOUR WORKINGS!!

Adolak:

This is wrong. The question is to find mass. Not mass conc. Then you used the H conc instead of OH concentration as it is NaOH.
I got 0.0202g though. Don't know if I'm correct

xcelentattitude:
Please, I need to know about total fees to be paid for the direct entry, subsequent school fee etc (please the real one, not the one different people are posting online) just finished my NCE with 4.something GP(the result is being uploaded now) in physics -mathematics.

Please,bosses in d house.What are the advantages & disadvantages of picking UI as 1st choice for medicine & surgery.?..What is another alternative university to UI for MBBS.?

TeflonBlixx:


Ph + Poh = 14

Poh = 14 - 10.5

= 3.5

Poh = -(log10OH)

3.5 = -LogOH

OH = Antilog -3.5

= Antilog 0.5 x Antilog -4.0
= 3.162 x 10^ -4

Since concentration = 3.16x 10 ^-4
Mass is unknown
Molar mass = 40g
Volume = 0.8dm3
C = n/v

Where the terms take their usual meaning.

3.16x 10^-4 x 0.8 = amount
amount = 2.528 x 10^-4

Amount = mass/molar mass

mass = amount x molar mass

= 2.528 x 10^-4 x 40g

mass = 101.12 x 10 ^-4

= 0.0101g..

Rursh:
UI post UTME past questions (2012-2017). newly added is the last year's questions.
before hurling jabs and inflammatory comments, why not take look at the screenshots below or better still, show it to those you wrote last year so as to confirm its authenticity.
for enquiries, call 08037737245.

Sulegee:
Guys pls how true is did??
Last year's aspirants needed pls

Dikachi483:


Well I think the advantage of picking UI as 1st choice is that if you have the requirements (high score in Jamb and post UTME... U r sure that there would be no foul play once you hit the cutoff... �

Bigboy289:
thanks,what about the disadvantages ?

Dikachi483:


As with other top universities, the competition is tough due to the large amount of qualified applicants apply for mbbs at UI... Both for Direct Entry and also through UTME

Bigboy289:
please,is there a solution to that problem ??

Dikachi483:

The solution bothers on the candidate for UI to prepare adequately and try as much as possible to beat competition by securing high scores in the UTME and Post UTME...... You need to challenge yourself, study hard and believe you can do it.... Learn from other people's mistakes and never fail to ask questions when u feel confused... (that's my pep talk)�

Bigboy289:
Thanks,are u in ui ?

Dikachi483:

Nope..... Also an aspirant for UI Mbbs.... Am applying through direct entry

TeflonBlixx:

Maximum height = 1/2 x g x t^2
= 1/2 x 10 x 1.5 x 1.5
= 11.25
Maximum height - Height of the window
11.25 - 5
= 6.25m above the window

Sofia01:

v=0 at maximum height
v=u- at
0=u -10*3
0=u-30
u=30m/s
: to get the maximum height
v'2=u'2 -2aS
(0*0)=(30*30)-2*10*S
0=900-20S
-900=-20S
divide by -20
S=45m
: distance above window =45-5
=40m

Can u pls gimmie yur number so i can dm u.... Wud like to knw if yur a law student or an aspirant as well....tnks

@DrBESTJC ANSWERS TO THE BIOLOGY QUESTIONS (1) A (2) C (3) D (4) C (5) A (6) A (7) D (8 ) A (9) D (10) C (11) A

TeflonBlixx:


1. Arboreal. . They 'live' on trees

2. Hermophrodite. . Monoecious flowers are not capable of self pollination

3. Cryptic colouration

4. Pancreas. .

5. Fatty foods cause obesity. . Magarine and butter

6. Prevents water logging. . Clayey soils are known for their soil water rententivity. . Adding of slake lime, Caco3 or gypsum helps loosen up the texture thereby reducing water logging

7. Occupy different ecological niches

8. Chisel like front teeth. .

9. C

10. Pericycle. . I'm not well versed in supporting tissues in plant...

11. Soil is already present. . From my soil science knowledge, primary succession is mostly slow due to weathering process of parent materials. . Believe me bro, weathering is a slow process..
