1. What is the unit of measurement for power?

• A. Joule (J)
• B. Newton (N)
• C. Watt (W)
• D. Kilogram-meter (kg·m)

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.

2. He likewise stresses the need for all the employees to follow orders and instructions from

• A. Scalar chain
• B. Discipline
• C. Unity of command
• D. Order

Correct answer: B

Rationale: The correct answer is B: 'Discipline.' In a business context, discipline refers to the adherence to rules, orders, and instructions to ensure smooth operations and efficiency. The concept of discipline is essential in maintaining order, consistency, and productivity within an organization. It encompasses obeying rules, following instructions, and respecting authority. While the other options like 'Scalar chain,' 'Unity of command,' and 'Order' are important principles in management, they do not directly address the importance of employees adhering to orders and instructions, which is the central focus in this question. Therefore, 'Discipline' is the most suitable answer in this context.

3. What is the pH value of a neutral solution?

• A. 0
• B. 7
• C. 14
• D. -7

Correct answer:

Rationale: A neutral solution has a pH of 7. The pH scale ranges from 0 to 14, with 7 being neutral.

4. Which term describes the ability of a substance to conduct electricity?

• A. Reactivity
• B. Density
• C. Conductivity
• D. Viscosity

Correct answer: c

Rationale: Conductivity refers to a substance's ability to conduct electricity. Substances that conduct electricity well are known as conductors.

5. What is the periodic table?

• A. A table of elements that are arranged in order of increasing atomic number.
• B. A table of elements that are arranged in order of increasing atomic mass.
• C. A table of elements that are arranged in order of their reactivity.
• D. A table of elements that are arranged in order of their color.

Correct answer: B

Rationale: The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties. Elements are arranged in rows (periods) and columns (groups) with similar properties. The elements are listed in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement reveals a periodic repetition of chemical properties, which is the basis of the periodic law.

6. Nuclear fusion powers the sun and other stars. What is the main obstacle to achieving controlled nuclear fusion on Earth for energy production?

• A. Lack of suitable materials to handle high temperatures and pressures.
• B. Limited availability of fusion fuels like deuterium and tritium.
• C. Difficulty in containing the plasma where fusion occurs.
• D. All of the above.

Correct answer: D

Rationale: The main obstacle to achieving controlled nuclear fusion on Earth for energy production involves a combination of factors. A) Lack of suitable materials to handle high temperatures and pressures is a significant challenge due to the extreme conditions required for fusion reactions. B) Limited availability of fusion fuels like deuterium and tritium can pose a constraint on the scalability and sustainability of fusion energy. C) Difficulty in containing the plasma where fusion occurs is another critical issue as plasma instabilities and heat losses can hinder the efficiency of fusion reactions. Therefore, all of the options (A, B, and C) contribute to the challenges in achieving controlled nuclear fusion for energy production on Earth.
