Reading
To calculate the focal length of a reading glass (convex lens), we can use the lens formula:
1/f = 1/v - 1/u
Given:
v = -75 cm (distance of distinct vision, negative because it's on the same side as the object)
u = -25 cm (normal near point, assume)
However, since the normal near point is not given, we'll use the formula for a simple magnifier:
f = D / (D/d - 1)
where D = 25 cm (normal near point) and d = 75 cm (distance of distinct vision)
f = 25 / (75/25 - 1)
f = 25 / (3 - 1)
f = 25 / 2
f = 37.5 cm
The focal length of the reading glass is 37.5 cm.
Hello,
It's completely normal to feel a bit anxious after reading mixed reviews online. However, AME CET (Aircraft Maintenance Engineering Common Entrance Test) is a recognized exam for admission to various AME institutes. It's not a scam, but like any other exam, there can be some negative experiences shared by candidates.
Hope it helps !

Question : Which of the following is an example of on-the-job training?
Option 1: Attending a university course
Option 2: Participating in a workshop
Option 3: Reading a book
Option 4: Learning from colleagues at work
Correct Answer: Learning from colleagues at work
Solution : The correct answer is (d) L
earning from colleagues at work. On-the-job training refers to the process of acquiring knowledge, skills, and experience while performing job duties and tasks within the actual work environment. It involves learning from more experienced colleagues, supervisors, or mentors who provide guidance, instruction, and hands-on training.
On-the-job training, on the other hand, occurs within the work setting and involves learning from colleagues who have practical experience and can provide guidance, support, and hands-on instruction related to the specific job requirements.
Question : Comprehension: Read the given passage and answer the questions that follow. Plato is the earliest important educational thinker, and education is an essential element in 'The Republic' (his most important work on philosophy and political theory, written around 360 B.C.). In it, he advocates some rather extreme methods: removing children from their mothers' care and raising them as wards of the state, and differentiating children suitable to the various castes, the highest receiving the most education, so that they could act as guardians of the city and care for the less able. He believed that education should be holistic, including facts, skills, physical discipline, music, and art. Plato believed that talent and intelligence are not distributed genetically and thus can be found in children born to all classes, although his proposed system of selective public education for an educated minority of the population does not really follow a democratic model.
Aristotle considered human nature, habit, and reason to be equally important forces to be cultivated in education, the ultimate aim of which should be to produce good and virtuous citizens. He proposed that teachers lead their students systematically, and that repetition be used as a key tool to develop good habits, unlike Socrates' emphasis on questioning his listeners to bring out their own ideas. He emphasized the balancing of the theoretical and practical aspects of subjects taught, among which he explicitly mentions reading, writing, mathematics, music, physical education, literature, history, and a wide range of sciences, as well as play, which he also considered important.
Question: Which of these statements is NOT true?
Option 1: Socrates encouraged the listeners to come up with original ideas.
Option 2: The Republic was written around 360 A.D.
Option 3: Socrates considered music and physical education as important aspects of learning.
Option 4: Plato's methods of education can be called 'extreme'.
Correct Answer: The Republic was written around 360 A.D.
Solution : The second option is the correct choice.
The statement the Republic was written around 360 A.D. is not true.
Explanation: The Republic, Plato's most important work on philosophy and political theory, was written around 360 B.C., not 360 A.D. The use of B.C. (Before Christ) and A.D. (Anno Domini) helps specify the historical period. Plato lived in ancient Greece, and his influential work was composed in the 4th century B.C., making the correct time reference.
Question : Select the most appropriate antonym to substitute the bracketed word in the given sentence. They are virtually unimpeachable in the (unbiased), invariably correct reading of a race.
Option 1: captivity
Option 2: stranger
Option 3: prejudiced
Option 4: ceasing
Correct Answer: prejudiced
Solution : The third option is correct.
Unbiased means not showing prejudice or favouritism and being fair and impartial. The antonym of unbiased is prejudiced, which means showing favouritism or a preconceived opinion based on incomplete information or stereotypes.
The meanings of the other words are as follows:
Captivity: It denotes the state of being captive or imprisoned; it is the condition of being held against one's will.
Stranger: It denotes a person whom one does not know or with whom one is not familiar; someone who is not a relative, friend, or acquaintance.
Ceasing: It denotes the act of coming to an end; the termination or stopping of something.
Therefore, the correct answer will be prejudiced.
