The pollutant that may induce the condensation of water vapour in the atmosphere is....
(A) dust
(B) soot
(C) oxides of nitrogen
(D) chlorofluorocarbons


Please,I need only the CORRECT ANSWER to this question.The two past-questions I use gave different answers to them.

The salt formed from a weak acid and a strong base hydrolyzes in water to form....
(A) a saturated solution
(B) an acidic solution
(C) a buffer solution
(D) an alkaline solution

I think the answer is D sir.
I stand to be corrected chiefly.

(A) dust
(B) soot
(C) oxides of nitrogen
(D) chlorofluorocarbons


Please,I need only the CORRECT ANSWER to this question.The two past-questions I use gave different answers to them.

The answer is C

When fossil fuels are burned, sulfur dioxide and nitrogen oxides are released into the atmosphere. Both of these air pollutants dissolve in water vapor to form acid

I might be wrong sha

BrightForYou:
Guys, JAMB's "Use Of English" used to be 100 questions. But now,it has been truncated to 60. Definitely some topics or aspects have been scrapped. I guess "REGISTER" is part of this. Please can those who sat for the MOCK exam tell us how the subject like now. In other to know what to read on and neglect. Thanks. Happy New Week.

Thanks Am so grateful. Can you also help me with this.
What is the force required to move a load of 50kg through a distance of 1000cm in 5s? (a)5N (b)10N (c)20N (d)30N (e)40N

Just saw my exam details now.

What is the force required to move a load of 50kg through a distance of 1000cm in 5s? (a)5N (b)10N (c)20N (d)30N (e)40N

SOLUTION

m = 50kg,

s = 1000 cm = 10 m

t = 5s

F = m a, s = ut + ½at² where u = 0m/s

s = ½at²

10 = 0.5 x 5² x a

10 = 12.5a

a = 0.8 m/s²

F = m a = 0.8 x 50

F = 40N

Using: F=ma
But, a=v/t
And V=s/t
therefore: F=ms/t^2.
Convert 1000cm to meters
1000cm=1000/100meters=10m
Therefore: F= 50kg (times) 10m (over) 5squared=20N.


Na nokia torch I de use .I hope you understood my explanation...

Abeg,I still need help here...

DrBESTJC:

B

Orezy5:

SOLUTION
m = 50kg,
s = 1000 cm = 10 m
t = 5s
F = m a, s = ut + ½at² where u = 0m/s
s = ½at²
10 = 0.5 x 5² x a
10 = 12.5a
a = 0.8 m/s²
F = m a = 0.8 x 50
F = 40N

I support this solution.
