Dear brother,

How are you doing? I hope that you are doing very fine. Health-wise we are alright, but we are facing a lot of hardships here in Nigeria. This is what spurred me to write this letter to you. As you are aware, there are severe economic difficulties in Nigeria and our family is not spared.

We are passing through a hard time now. In the last eight months, things have gone bad for daddy and mummy. Daddy was retrenched August last year and since then, he has not been able to get another job. Four months after hrs. retrenchment, he sold the land that he bought few years back with the aim of setting up a soap business. He actually started the soap-making business but the harsh economic situation snuffed life out of the business. That was how the big sum of money daddy invested in the business went down the drain.

Daddy's misfortune has really affected mummy's business badly. Can you believe that mummy's shop which was usually filled to the brim with wares is now a shadow of its former self? All the capital that mummy used to re-cycle into the business has been used to feed the family since daddy can't provide money for feeding again.

Bimbo and Tunde have been withdrawn from the private primary school they were attending before to the public school near our house. I was offered an admission to read Accountancy at the Ogun State Polytechnic last year and I couldn't register because there was no money. The experiences are terrifying and traumatic. There is always bickering and quarreling in the family nowadays; a bad and ugly thing that was never given a chance in the family in the past. Daddy feels touchy and, in most cases, visits his frustration and anger on mummy and us.

Brother Kunle, the family needs your assistance financially now more than ever before. I know that you'll not be happy to see the family in shambles and to save daddy from developing hypertension, you should send some money to assist him. Mummy too needs your assistance to revamp her business. Her shop will soon be closed totally unless you send some financial assistance to her.

We shall be expecting your assistance very soon. Extend my greetings to your wife and the children.

Yours sincerely.

Kola.

Correct Answer: D. 6 : 1

Explanation

\(\frac{V_1}{V_2}\) = \(\frac{I_1R_1}{I_2R_2}\)

\(\frac{I_1}{I_2}\)V₂ = 3V₁ and R₁ = 2R₂

\(\frac{V_1}{3V_1}\) = \(\frac{I_1 \times\ 2R_2}{I_2\times R_2}\)

\(\frac{I_1}{I_2}\) = \(\frac{6}{1}\)

Correct Answer: A) debited to the asset account and credited to the hire purchase vendor

Correct Answer: B. 0.0084N

Explanation

\(F = mass \times acceleration\) but \(accl = \frac{v - u}{t}\)

\(\therefore F = m(\frac{v - u}{t})\)

\(Mass = 28g = 0.028kg\)

\(v = 5.4 ms^{-1}; u = 0; t = 18secs\)

\(\therefore F = 0.028(\frac{5.4 - 0}{18}) = 0.028 \times 0.3 = 0.0084N\)

Correct Answer: D. structures and systems for decision-making in society

Explanation

(a) Differences between Local time and Standard time

1. Local time varies from one longitude to another at the rate of 4 minutes per degree of longitude whereas standard time varies from one time zone to another on hourly basis of 15° of longitude to 1 hour.

2. Standard time maintains the central time for time zone in which they are, whereas local time varies from one place to another within a time zone.

3. Standard time falls within 24 time zones whereas local time varies irregularly from longitude to longitude within each time zone.

4. Standard time is associated with Greenwich Mean Time, whereas local time is not.

(b) Calculations of Longitude

Time in town A is 7.46 p.m

Time in town B is 5.30 a.m

Time difference is 19.46 hours — 5.30 hours

Time difference is 14 hours 16 minutes

If 1 hour = 15° or 1° = 4 minutes

Therefore, 14 hours 16 minutes 7:- 214°

If town A is on longitude 70°E so town B's time is behind

Therefore, subtract 70° from 214° = 144°W.

Correct Answer: B) Secchi Disc.

Explanation

Turbidity is a measure of how cloudy or murky water is due to the presence of suspended particles. To determine the turbidity of water, an instrument is needed. In this Biology question, we are asked to identify which instrument is used to determine the turbidity of water. Option A, thermometer, is not the correct answer. A thermometer is used to measure temperature, not turbidity. Option C, rain gauge, is also incorrect. A rain gauge is used to measure the amount of rainfall, not the turbidity of water. Option D, hygrometer, is also not the correct answer. A hygrometer is used to measure humidity, not the turbidity of water. The correct answer to this question is option B, Secchi Disc. A Secchi Disc is a circular disk typically painted white and black or white and red, which is lowered into the water until it disappears from sight. The depth at which it disappears gives a measure of the turbidity of the water. In conclusion, the instrument used for determining the turbidity of water is the Secchi Disc. Other instruments such as thermometer, rain gauge, and hygrometer are used to measure different environmental variables.

Correct Answer: B) rainfall

Explanation

The question is asking about what God did in response to Elijah's prayer after the contest on Mount Carmel. The options are thunder, rainfall, a whirlwind, and a heavy storm. The correct answer is option B, rainfall.

After Elijah had challenged the prophets of Baal and proved that the God of Israel is the true God, he prayed for rain to end the three-year drought in Israel. God answered his prayer by sending a heavy rainfall, ending the drought and bringing fertility to the land. Rainfall is a symbol of God's blessing and provision.

As Christians, we believe in the power of prayer and that God still answers prayers today. Elijah's story teaches us to trust in God and to pray with faith, knowing that He hears us and will answer in His own time and way.

Correct Answer: C. 0.80ms^-2

Explanation

S = ut + \(\frac{1}{2}\)at\(^2\)

40 = 0 x 10 + \(\frac{1}{2}\)a x 10\(^2\)

50a = 40

a = \(\frac{40}{50}\)

= 0.8m/s\(^2\)
