Correct Answer: D. reveled in Arabic

Correct Answer: C. to increase farmers'incomes and improve the farming techniques

Correct Answer: D) Dividend received on behalf of customer

Explanation

(a)(i) Cost-push inflation; occurs when increases in cost of production are passed on to consumers in form of high prices while Demand — pull inflation occurs when consumers have high purchasing power, aggregate demand increases without corresponding increase in supply.

(b) Inflation can be controlled in the following ways:

(i) It can be controlled by increasing the output to bring down the prices.

(ii) It can be controlled with the use of fiscal measures to reduce the amount of money in circulation e.g. increase in direct taxation.

(iii) The use of contractionary monetary measure, by increasing the bank rate, open market operation, etc. can also control inflation.

(iv) The use of price control by government officials and the application of rationing to maintain the price level is also another inflation control measure.

(v) Another way is by granting subsidy to enterprises and companies producing essential products to reduce cost of production and the products' prices.

(vi) Removing bottlenecks in the distribution system i.e. provision of good roads, storage facilities, etc is another means of controlling it.

(vii) Government should discourage importation from countries already experiencing inflation, as a way of controlling it.

(viii) Use of income policies such as wage freeze, delay in promotions, etc. is a way of controlling inflation.

Explanation

(a)Vertebrae with corresponding location

(ii) Vascular bundle

- Contains xylem for transport of water/mineral salts/phloem for translocation of manufactured organic substances/hormones;

- Provides mechanical support;

(iii) Epidermis

- It keeps the leaf’s shape;

(c) Function of

(i) Sieve tube

- Translocates/transports manufactured foods to other parts of the plant;

(ii) Cortex

- The cells of cortex store starch;

- Outer cortex cells of green stems contain chloroplasts and make food by photosynthesis/chlorophyllus cortex cells manufacture food;

(iii) Pith

- Cells of pith act as packing/food storage tissues;

- Supports the stem;

(d) Structural differences

(i) External structural differences between stem and root of a maize seedling

(ii) Internal structural differences between stem and root of a maize seedling

Correct Answer: B. 225 cm3

Explanation

ai. Electric potential at a point is defined as the work done in bringing a unit positive charge from infinity to that point against the electrical forces of the field.

ii. Process of Charging:

Induction: Involves redistributing charges within an uncharged body without direct contact with a charged object.

Contact: Requires direct physical contact with a charged object to transfer charges.

- Nature of Final Charge:

Induction: Results in a charge of opposite polarity to the charged object initially brought close.

Contact: Results in a charge of the same polarity as the charged object with which contact is made.

b. - Safety: Opening the circuit prevents current from flowing, which reduces the risk of electric shock. This is especially important when working with high voltages or currents.

- Conservation of battery power: If the circuit is left closed, the current will continue to flow even when no readings are being taken. This can drain the battery and shorten its lifespan.

- Accurate readings: If the circuit is left closed, the current flowing through the circuit can cause the components to heat up. This can affect the accuracy of the readings.

- Protection of equipment: If the circuit is left closed, a surge of current could flow through the circuit if there is a fault. This could damage the equipment or even cause a fire.

c. \(Z^2 = R^2 + X{_L}^2\)

\(Z^2 = R^2 + (2πf_L)^2\)

\(Z^2 = R^2 + 4π^2f^2L^2\)

\(Z^2 = 4π^2f^2L^2 + R^2\)

∴ \(Z = \sqrt{4π^2L^2f^2 + R^2}\)

ii. from the equation

\(Z^2 = 4π^2f^2L^2 + R^2\)

using y = mx + c = y = \(Z^2\), x = \(f^2\)

m = \(4π^2L^2\) = slope of the grape

m = \(\frac{ Z_2^2 - Z_1^2}{f_2^2 - f_1^2} = \frac{ 700 - 200 }{ 800 - 140 }\)

\(4π^2L^2 = \frac{ 500}{ 660}\)

\(L^2 = \frac{ 500}{ 660} \times \frac{1}{ 4π^2} =\frac{ 500}{ 660} \times \frac{1}{4 \times 10}\) ( since \(π^2\) = 10)

\(L^2 = 0.0189\)

∴ L = \(\sqrt{ 0.0189}\) = 0.138H = 138mH

Correct Answer: C) Elijah

Explanation

The question is asking who said the statement, There shall be neither dew nor rain this year except by my word. The options to choose from are: Moses, Pharaoh, Elijah, Esther, and Paul. The correct answer is option C, which is Elijah.

Elijah was a prophet in the Old Testament who spoke for God. He lived during a time when the Israelites were worshiping false gods and had turned away from God. Elijah warned the people to turn back to God, but they did not listen. As a result, God punished them by sending a drought upon the land. Elijah then told King Ahab that there would be no rain or dew until he said so.

This statement shows that Elijah had great faith in God and was confident in his ability to speak for God. It also demonstrates that God has power over nature and can use it to show his displeasure or favor towards his people.

In summary, Elijah said the statement, There shall be neither dew nor rain this year except by my word, as a warning to the people of Israel to turn back to God.
