Explanation

(a) \(d = 15 cm \implies r = \frac{15}{2} cm\)

\(V = \frac{4\pi r^{3}}{3}\)

\(V = \frac{4}{3} \times \frac{22}{7} \times (\frac{15}{2})^{3}\)

\(V = \frac{1125 \times 22}{7 \times 2}\)

\(V = 1,767.857 cm^{3}\)

(b)(i) Longitude difference : 105° + 35° = 140°

Distance along the parallel of latitude = \(\frac{140}{360} \times 2 \times \frac{22}{7} \times 6400 \cos 28\)

= \(\frac{140 \times 44 \times 6400 \times 0.8829}{360 \times 7}\)

= \(13812.48 km\)

\(\approxeq 13800 km\)

(ii) Distance from the equator : \(\frac{28}{360} \times 2 \times \frac{22}{7} \times 6400\)

= \(3128.89 km\)

\(\approxeq 3130 km\)

Correct Answer: A. General Murtala Muhammed

Explanation

(a) Eli, a priest at Shiloh, had two worthless sons. They committed acts of immorality with female worshippers at Shiloh and they also desecrated sacrifices offered to God. The report eventually came to Eli and prophesied doom on his family, but Eli did nothing more to stop the unholy act. A man of God also came to Eli and prophesied doom on his family. And even when God confirmed the prophecy through Samuel, Eli just said "It is the Lord, let Him do what seems good to him."

(b) As a result of Eli's parental irresponsibility, Israel suffered in the following ways:

(i) God sent the Philistines to fight Israel.

(ii) Israel was defeated in the war.

(iii) About three thousand Israelites died in the war.

(iv) Hophni and Phinehas, the two sons of Eli, the priest, were among those killed.

v) Those who survived in the battle fled.

(vi) The Ark of the Lord was captured by the Philistines.

(vii) When Eli heard that the enemy captured the Ark of the Lord, he fell backwards, broke his neck and died.

(viii) When Eli's daughter-in-law heard the bad news, she had a premature baby and she died.

(ix) That baby was named "Ichabod", meaning, "glory has departed from Israel".

(c) The lessons that can be derived from the attitude of Eli are:

(i) Parents should take time to teach their children the word of God.

(ii) There is need to pray together-the use of the family altar should be of paramount importance.

(iii) Parents should inculcate in their children the spirit of fear of God in all they do.

(iv) There is need to heed the warning of prophets/men of God.

(v) The consequences of evil relationship between men and women must be pointed out to children.

(vi) Disobedience to the commandments of God could bring adverse consequences.

Explanation

(a) Differences between Weather and Climate

— Weather is the atmospheric condition of a place over a short period (days, weeks, hours, months) but climate is the average weather conditions of a place over a long period of time (35yrs).

— Weather changes very often, but climate does not change very often.

— Weather cannot be generalized but climate can be generalised.

— Weather describes the atmospheric condition of a small area, while climate describes the atmospheric condition of a large area.

(b)Some Weather Elements and the Instruments for Measuring them

— Wind speed

— anemometer,

— Sunshine - sundial / recorder, campbell stroke,

— Pressure

— barometer

— Rainfall

— rain gauge.

(c) How Wind Speed is Measured

— Measured with anemometer

— Placed in an open space

—Anemometer consists of four metal cups fixed to a metal arm

— The shaft is connected to a meter

—The cups rotate freely on a vertical shaft as the wind blows.

— The number of rotation is indicated on a meter to give the speed of the wind in kilometer per hour. How Wind Speed is Recorded

— Reading is taken twice daily e.g 9.00 hours and 1500 hours

— Is recorded in a note book

— Stating the date of recording

— The record is signed by the observer.
