Correct Answer: C. the name of a bank is written across it

Correct Answer: C. Berlin conference

Explanation

Berlin Conference of 1884/85 laid a strong foundation for colonial intervention in Africa.

Explanation

(a)

A mass of dry air is entrapped in a uniform capillary tube, sealed at one end, by means of a mercury pellet. Both the tube and thermometer are then firmly attached a half-meter rule and placed in a water bath as shown above. The water is stirred and its temperature \(\theta_{1}\) at a steady state is noted. The corresponding length, \(L_{1}\) of the entrapped air is also noted and recorded. The water is gradually heated and stirred uniformly until another steady temperature, \(\theta_{2}\) is attained and recorded. The corresponding length, \(L_{2}\) of the air column in the capillary tube is again read and recorded. The experiment is repeated to obtain more sets of readings. A graph of L against \(\theta\) is plotted as shown.

Deduction: Since the volume V of the tube is proportional to its length, L the graph shows that the volume of the entrapped air increases (directly) with increase in temperature at constant pressure.

Precautions: Dry air must be used. Also, error of parallax in reading thermometer and meter rule avoided.

(b) \(S = \frac{V_{1} - V_{0}}{V_{0} \theta}\)

= \(\frac{18.7 - 13.7}{13.7 \times 100}\)

= \(\frac{5}{1370}\)

= \(3.65 \times 10^{-3} K^{-1}\)

(c) As temperature increases the kinetic energies the molecules increase and they bombard the wall the container at a faster rate since their velocities has increased. To keep the rate of change of momentum per unit area (i.e pressure) the same, the molecules will have to travel longer distances betweon collision This implies increase in volume.

Correct Answer: C. Epic

Explanation

In literature, an epic is a long narrative poem, which is usually related to heroic deeds of a person of an unusual courage and unparalleled bravery.

Correct Answer: B. resolution

Correct Answer: C. tropics of cancer and capricorn

Correct Answer: D) issuing currency notes

Explanation

Currency notes are the paper money that we use to buy goods and services. They come in different denominations, such as Naira, Dollar, Euro, etc. The Central Bank ensures that there is enough supply of currency notes to meet the needs of the economy.

By issuing currency notes, the Central Bank helps to maintain the stability of the currency and ensures that there is enough money in circulation for people to use in their daily transactions.

So, in summary, the service rendered by the Central Bank is issuing currency notes. This is an important role that helps to facilitate economic activities in the country.

Please note that this explanation is based on general knowledge and may vary slightly depending on the specific country and its Central Bank.

Correct Answer: A. currency

Explanation

Political and economic integration can be hindered by powerful colonial ties, religion and political instability but currency should not be an obstacle because there should be an established exchange rate.

Correct Answer: D. Orsino

Correct Answer: D. 194
