Correct Answer: B. increasing population

Explanation

Underdevelopment in Africa is as a result of many contributing factors which include poverty, illiteracy, very large extended families, corruption and lack of accountability. Poverty is one of the causes of underdevelopment in Africa. Unfortunate events such as slave trade, wars and other bad incidents

Correct Answer: D. defective

Correct Answer: C. 0.00247

Correct Answer: B. regressive

Explanation

Indirect taxes; An indirect tax is a tax levied on goods and services rather than on income or profits. indirect taxes are regressive in nature. They are consumption based taxes. Service tax, value added tax,customs and excise duty etc are examples of

Taxes are regressive when they impose a harsher burden on the poor than on the rich.

Correct Answer: C. 5cm

Explanation

Volume of a cube with side a cm = a\(^3\)

a\(^3\) = 64 \(\implies\) a = 4cm

Base area of a cube = a\(^2\)

= 4\(^2\)

= 16 cm\(^2\)

\(\implies\) Base area of the cuboid = 16 cm\(^2\)

Volume of cuboid = Base area x height

80 = 16 x h

h = \(\frac{80}{16}\)

= 5 cm

Explanation

a) Average velocity = \(\frac{u + u}{2}\)

From equation V = u + at

Aeverage velocity = \(\frac{u + u + at}{2}\) = \(u + \frac{1}{2} at\)

Distance covered = Ave. vel. x time

x = (u + \(\frac{1}{2}\)at)t

x = ut +s

(b)i) Newton's second law of motion states that the of change of momentum is proportional to the lied force and takes place in tho direction of the force.

(ii) The principle of conservation of energy es that energy is neither created nor destroyed can be changed from one form to another. The law of floatation states that an object wil t in a fluid when the upthrust exerted upon it by fluid in which it floats equals the weight of the

(c) Mass of air displaced = mass of ballon on and contents V x density of A air

= V x density of gas + content

V x 1.29 = v x 0.54 + 0.030

V = \(\frac{0.03}{0.75}\) = 0.04m\(^{3}\)
