In a perfectly competitive market, there are many buyers and sellers who are all selling identical products, and there are no barriers to entry or exit. This means that no individual seller or buyer has any control over the market price.

The correct answer to this question is Option C: firm

Correct Answer: A. is handy but not readily available for all citizens

Correct Answer: C. obvious

• Imperceptible means impossible or very difficult to perceive, see, or notice (subtle, undetectable).

• Obvious means easily perceived, seen, or recognized, which is the direct opposite in meaning.

*(Note: Negligible and obscure are closer in meaning or related to imperceptible, while significant usually serves as an antonym to negligible or insignificant.)*

Correct Answer: (B) compound sentence

Correct Answer: A. motion, the field and the induced current

Explanation

Fleming's Right-Hand Rule is used to determine the direction of induced current when a conductor moves in a magnetic field. When the thumb, forefinger, and middle finger are held mutually at right angles:

• Thumb: Represents the direction of Motion (or Thrust/Force) of the conductor.

• Forefinger: Represents the direction of the Magnetic Field.

• Middle Finger: Represents the direction of the Induced Current.

Therefore, the correct representation is:

• Thumb: Motion

• Forefinger: Field

• Middle finger: Induced current

Comparing this to the options:

A. motion, the field and the induced current - This matches perfectly.

B. induced current, the motion and the field

C. field, the induced current and the motion

D. induced current, the field and the motion

The correct answer is A.

Dear Chioma,

I don't think that I can ever be happy again until we settle our quarrel and become friends again. I never thought that the little misunderstanding caused by mischievous Ngozi could make us not to be on speaking terms for almost two years now. I referred to Ngozi as being mischievous because what she told me about you as regards the stolen money in our dormitory has been revealed to be untrue. She made me to believe that you were the one who stole the money. I a m very sorry to have joined others to accuse you wrongly which had made you to vow not to be on speaking terms with me again.

Chioma, I want to let you know that the quarrel has caused me a lot of things. In fact, it has strained my good relationship p with my mother. She keeps asking after you. wondering why you've not be visiting me during holidays. I didn't know that she loves you so much until she pestered me to tell her what happened between us. She promised to come and see you and she refused to give me money when I was coming back to school because of the quarrel between us.

In addition to this, I missed your companionship and the friendship that has been built over a period of five years. If you could recollect we got admitted into this school the same day and since then we have been known to be friends. We did many things together and because of the quarrel. many people. including some of our teachers, have been wondering what has come between us. I think we should not allow any quarrel to separate us and I sincerely desire that we become friends again.

Furthermore, what begins well must end well, We are known to be friends right from our junior secondary school and we should pass out of the senior secondary school as friends. It won't be good for us to meet after our stay in this school and refuse to greet each other. We should be able to burry the hatchet so that our friendship could go beyond our stay in secondary school. Don't you think that I will still need your inestimable companionship and advice after we must have left the school?

My mother will be very happy to hear that we have put the quarrel behind us and I am sure that your parents must have been asking you about me. Let us put an end to the quarrel and malice and restore our friendship. How are you? I hope that you are doing well academically. I am looking forward to when you are going to pay me a visit in my dormitory.

Yours sincerely.

Oluchi.
