Optimist1998:
I. Its velocity is constant
II. No work is done on the body
III. It has constant acceleration directed away from the centre
IV. The centripetal force is directed towards the centre

Which combination of the above is true of a body moving with constant speed in a circular track?
A. II and IV
B. I and IV
C. II and III
D. I and III

Am sure it is not 3 cos the acc is always directed to towards the center and can't be one also.. I mean its direction is constantly changing I think. Inshort it should be A

a rainbow is viewedthrough a blue sheet of glass. the rainbow will appear. a. white b yellow c. blue d none of the above. explain

I think it is C... All the colour apart from blue absorbs d blue light but can not reflect it. Only blue reflects. I don't know it might be nonsense but that's what I think

Optimist1998:
Guys let's try this....
A catapult used to hold a stone of mass 500g is extended by 20cm with an applied force F. If the stone leaves with a velocity of 40m/s, the value of F is
A. 4.0 x 10²N
B. 2.0 x 10³N
C. 4.0 x 10³N
D. 4.0 x 104N

I noticed there's a gross misconception about this question.

Dist=0.2m mass=0.5 V=40m/s
V^2=U^2 + 2as. V=0
-U^2=2as
(-40)^2=2(0.2)xa
1600=0.4a
a=4000
F=ma
F=0.5x4000
F=2000.
Ans=B

Nuel25846:
when will they send the result self??

will they? Wat are u expecting?

Nuel25846:
ur type will be expecting to score 400 and above.

Most people on myschool.com.ng said the venue didn't change. They only altered the date.

. Did they do it on a system or a phone

Optimist1998:
I thought that problem was for people that did not indicate their interest during registration
I'd I've said exercise patience but the mock is in 3 days. Just keep trying or you could mail jamb if it persists.

Maybe am doing it the wrong way.. Have u seen anyone reprint his/her own.. Maybe u can give me some tips on how to check it

Optimist1998:

Optimist1998:
I assumed they're typos 'cause m/hr looks strange to me

same here but I think u shld let him correct that

✅Head wind opposes the motion of the plane, resultant velocity = 80-10 = 70km/hr
✅Tail wind from behind= 80 + 10=90km/hr
✅10km/hr crosswind (Pythagoras rule) = √(10²+80²) =80.62km/hr
✅60km/hr crosswind(thesame method above) =100km/hr

.
Dude the options are in m/hr not km/hr

who have reprint his/her own jamb slip for the mock

Abeg who av reprint his/her jamb slip for the exam center stuff

For a concave mirror to serve as dentist mirror, the object must be placed btw the_________ and_________ of the mirror

I think for it to serve as a wateva mirror it must be enlarged and erect.. So there is only one spot u get dat kind of combo I.E btw the pole and principal focus of the mirror.

Optimist1998:

castrokiller:
The following events take place during conjugation in spirogyra 1. The protoplasm of each of the conjugating cell separate from the cell wall to form a Gamete; the gamete of one filament passes through the conjugation tube to meet the gamete of the other filament 2. The zygote soon become surrounded by thick brown wall to become zygospore which burst after a short rest and germinate to produce a new filament 3. The nuclei of the gametes fuse to form a zygote 4. The protuberance meet and where they touch the cell-wall disappear so that a conjugation tube joining the two cell is formed 5. protuberance appear on the wall of the cell of two filament of spirogyra lying side by side opposite one another. Now what is the correct sequence in which the above sequence occur?

A. 1,2,3,4,5
B. 1,2,4,5,3
C. 3,4,5,2,1
D. 5,4,1,3,2
E. 5,4,3,1,2

But guy why... How do u expect us not to cheat

The solubility of a salt of molar mass 101g at 20°C is 0.34 mol dm-3. If 3.40g of the salt is dissolved completely in 250cm3 of water in a beaker, the resulting solution is
A. A suspension
B. Saturated
C. Unsaturated
D. Supersaturated

C I think

Optimist1998:
Most likely precipitate.
The only colloidal solutions I know are Sols, gels and emulsions that's glue, starch, syrup etc.

I don't get... How is it a ppt

kristian98:
wao!!! To think someone who wants to study pharmacy will say this baffles me. What happened to your dreams and aspirations Or you have none Are u really going to study pharmacy in uni based on your passion or u just need a certificate. Well, i guess u have set a path for yourself already. You have limited yourself to think pharmacists are chemist so i wish u a happy life dispensing drugs

Dude am being realistic not limiting... U can keep living in dream land till u graduate and know how it is going in NIGERIA. I also have a cousin dat is a phamacist and dat is wat she said they do »»»» DISPENSE DRUG

kristian98:
not my fault. His comment irritated me. Its even pharmacists that produce drugs that doctors use sef

Pharmacist in Nigeria kind of dispense drug only. At least that's what I know from d people I ask.
So phamacist are educated version of chemist I think

kristian98:
so u think thats what pharmacy is all about Your comment really made me furious.
Check google about achievements of pharmacists and i bet u, it will leave u agog. You're implying pharmacy is not something worth learning whereas, its even a professional course. Pls avoid controversies

Kristian is taking it personal

Calcium tetraoxosulphate(VI) dissolves in water sparingly to form A solution B suspension C precipitate D colloid. Pls explain

Optimist1998:
I think it's A too

. U are not even sure... No be u post question?

Adebunmiemmy:
1.A 2.B
A z correct cz NaCl z an ionic compound,,so it exists as aggregate of ions in solid state
It cnt b D cz its mostly covalent compounds dat exist as discrete molecules and cnt b C cz it has an high meltn pt due to d strong electrostatic force
E z entirely out

.
Take a bow... U are right about d first one

Optimist1998:
Which of the following statements is correct about sodium chloride in the solid state?
A. it exists as aggregates of ions
B. it conducts electricity
C. its melting point is below 100oC
D. it exists as discrete molecules
E. its ions are linked by metallic bonds

Which of the following reactions is not feasible?
A. Cl2 + 2Kl → 2KCI + I2
B. Cl2 + 2NaF → 2NaCI + F2
C. Zn + CuCI2 ZnCl2 + Cu
D. Zn + 2AgNO3 → Zn(NO3)2 + 2Ag

.Regarding d first one, it should not be A I tink B is out it, I don't tink it shld be C or E. So am going with D

Optimist1998:
What will happen if an aluminium spoon is used to stir a solution of iron (II) trioxonitrates (V)?
