Correct Answer: B. 0.18

Explanation

a = \(\frac{v^2 + u^2}{2s} = \frac{0^2 + 3^2}{2 \times 2.5}\) = 1.8m/s2

F = ma = 25 x 1.8 = 45N

N = mg = 25 x 10 = 250

but \(\mu = \frac{F}{R} = \frac{45}{25 \times 10} = 0.18\)

Correct Answer: B. slate

Correct Answer: A. broadcast

Explanation

Ever since my return from our village where I spent my last holiday, I have been longing for an opportunity to pay another visit. Life is more pleasurable in the village than in Lagos. The quality of life in the village has forced me to abandon my earlier assumption that there was no life outside Lagos.

To say the least, real life exists only in our villages, if what I experienced in our village is anything to go by Everything about the village is simple. Apart from the fresh air and the vegetation, food and water are fresh. The food is not synthetic as in Lagos. Throughout m stay, I ate fresh food and fruits. My grandmother procured all the ingredients with which she cooked my meals from the e farm. She would grind the pepper on her grinding-stone which makes her soup more delicious and tastier than the ones prepared by my mother because she uses blender. Fruits like pawpaw, orange and pine-apple are allowed to ripe before they are plucked for eating. This is not so in Lagos and other cities as these fruits are plucked unripe and buried to force them to ripe. Food items are in abundance and very cheap unlike Lagos where they are very costly.

The scenery of the village is better imagined than to be told. Unlike in the city where houses are crowded together, huts are built in a way that flow of air is not obstructed. Much more air circulates in the village than in the city. This makes the villagers to be more healthy than city-dwellers. The huts are built wide apart. This makes cross ventilation possible. The whole village is built on a beautiful landscape and naturally in a way that makes the entire scenery of the village more beautiful than the city.

Human lives and property are more secured in my village than Lagos. I can remember that I forgot my clothes which I had washed and spread on the grass beside my grandmother's but and went to sleep one night. The following morning, the clothes were still intact, where I had spread them. My grandmother told me that nobody would steal them even if they were there for months. There was no incident of theft or robbery throughout the period of my stay in the village. The phenomenal incidences of abduction and killing of human beings to make money do not occur in my village. Everybody is a good neighbour as the people live peacefully with one another. They are more contented than those who are living in the city. They are not in a hurry to acquire wealth, though they are very hardworking.

My village people have good conduct and morals. The children do not misbehave unlike in the city where children turn to hooliganism and other immoral acts. They are properly taught and trained in ethics. Every evening before we go to bed, we would gather outside my grandmother's but and she would tell us stories which have good moral lessons.

The elders, unlike those in the city, are never in a hurry to pass by without words of greetings and blessing. They will ask after your family and health endlessly. In the city, this is not obtainable as everybody goes his or her way every morning without caring to utter a word of greeting.

I enjoyed my brief stay in my village because I felt relaxed without any anxiety or fear for anything. I had put on so much weight by the time I returned to Lagos. My health improved greatly as I ate to my satisfaction I was not really happy by the time I had to come back, though I had to because school was about to resume.
