PHYSICS

1. Marching soldiers crossing a suspension bridge are usually advised to break their steps to avoid damaging the bridge owing to
A. oscillation
B. resonance
C. swinging
D. vibration

See the Answer

The correct answer is B.

Explanation
Marching soldiers crossing a suspension bridge are usually advised to break their steps to avoid damaging the bridge owing to resonance. The steps of the marching soldiers can set the bridge into vibration, and when the frequency of the bridge is equal to that of the steps of the soldiers, the resonance occurs, and at this resonance, the bridge vibrates violently with maximum amplitude and can collapse.

2. Particles of mass 10−2kg are fixed to the tip of a fan blade which rotates with an angular velocity of 100rad-1. If the radius of the blade is 0.2m, the centripetal force is

A. 2 N
B. 20 N
C. 200 N
D. 400 N

See the Answer

The correct answer is B.

3. A thin converging lens has a power of 4.0 diopters determined by its focal length.

A. 2.50m
B. 0.03m
C. 5.00m
D. 0.25m

See the Answer

The correct answer is D.

EXPLANATION

the power of a lens is defined as the reciprocal of the focal length, expressed in meters. Mathematically, the power of a lens in dioptres is given by:(1)/f(in cm).
thus for lens of power of 4.0 dioptres we have that: (1)/(f) = +4.0
f= (1)/(4.0)
= 0.25cm

4. A real image three times the size of an object is formed 24cm from a converging mirror. what is the focal length of the mirror?
A. 16cm
B. 6cm
C. 8cm
D. 12cm

See the Answer

The correct answer is B.

EXPLANATION

for a real image 3 times the size of the object, it implies that the magnification 3 = v/u, 3 = 24/u, therefore 3u = 24, u = 8cm thus we have from the relation:m = (f)/(u)-f; that 3 = (f)/(8) – f. therefore f = 3(8-f) f = 24 – 3f ∴4f = 24; f = 6cm OR: (1)/(u) + (1)/(v) = (1)/(f).
(1)/(8) + (1)/(24) = (1)/(f)
therefore (3+1)/(24) = (1)/(f)
4/24=1/f;therefore 4f = 24
f = 6cm

5. The pair of physical quantities consisting of vectors only are
A. momentum and power
B. velocity and distance
C. displacement and torque
D. acceleration and speed

See the Answer

The correct answer is C.

MATHEMATICS

1 A group of market women sells at least one of yam, plantain, and maize. 12 of them sell maize, 10 sell yam, and 14 sell plantain. 5 sell plantain and maize, 4 sell yam and maize, 2 sell yam and plantain only while 3 sell all three items. How many women are in the group?

2. A group of market women sells at least one of yam, plantain, and maize. 12 of them sell maize, 10 sell yam, and 14 sell plantain. 5 sell plantain and maize, 4 sell yam and maize, 2 sell yam and plantain only while 3 sell all three items. How many women are in the group?

A. 25
B. 19
C. 18
D. 17

See the Answer

The correct answer is A.

EXPLANATION

Let the three items be M, Y, and P.
n{M ∩ Y} only = 4-3 = 1
n{M ∩ P) only = 5-3 = 2
n{ Y ∩ P} only = 2
n{M} only = 12-(1+3+2) = 6
n{Y} only = 10-(1+2+3) = 4
n{P} only = 14-(2+3+2) = 7
n{M∩P∩Y} = 3
Number of women in the group = 6+4+7+(1+2+2+3) as above =25 women.

3. A trader bought 100 oranges at 5 for N1.20, 20 oranges got spoilt and the remaining were sold at 4 for N1.50. Find the percentage gain or loss.

A. 30% gain

B. 25% gain

C. 30% loss

D. 25% loss

See the Answer

The correct answer is B.

EXPLANATION

Cost price (cp) = (100/5) x N1.20 =N24.00
Selling price (sp) = 100-20 = 80
(80/4) x N1.50 = N30.00

Gain = SP-CP = N30.00-N24.00 = N6.00
Gain% = (gain/CP) x 100 = 25%

4. Tope bought X oranges at N5.00 each and some mangoes at N4.00 each. if she bought twice as many mangoes as oranges and spent at least N65.00 and at most N130.00, find the range of values of X.

D. 8≤X≤10

See the Answer

The correct answer is C.

5. The sum of two numbers is twice their difference. If the difference between the numbers is P, find the larger of the two numbers

A. p/2

B. 3p/2

C. 5p/2

D. 3p

See the Answer

The correct answer is B.

EXPLANATION

Let the numbers be x and y
x+y = 2p…..(i)
x-y = p……(ii)
2x = 3p
x = 3p/2
