1. The primary function of the strong nuclear force is:

• A. Binding electrons in atomic orbitals
• B. Binding protons and neutrons within the nucleus
• C. Mediating the attractive force between opposite charges
• D. Mediating the repulsive force between like charges

Correct answer: B

Rationale: The strong nuclear force is responsible for binding protons and neutrons within the nucleus. This force is crucial for overcoming the electrostatic repulsion between positively charged protons in the nucleus, holding the nucleus together. Option A is incorrect as it refers to the role of the electromagnetic force in binding electrons in atomic orbitals. Option C describes the electromagnetic force that mediates the attraction between opposite charges, while option D refers to the electromagnetic force mediating the repulsion between like charges. Understanding the primary function of the strong nuclear force helps explain the stability and structure of atomic nuclei.

2. The body's first line of defense against pathogens is the innate immune system. Which of the following is NOT a component of the innate immune system?

• A. Physical barriers like skin and mucous membranes
• B. Phagocytes that engulf and destroy pathogens
• C. Inflammatory response to isolate and contain infection
• D. Production of antibodies specific to a particular pathogen

Correct answer: D

Rationale: The innate immune system is the body's first line of defense against pathogens and includes physical barriers like skin and mucous membranes, phagocytes that engulf and destroy pathogens, and the inflammatory response to isolate and contain infection. However, the production of antibodies specific to a particular pathogen is a function of the adaptive immune system, not the innate immune system. The innate immune system provides immediate, nonspecific defenses, while the adaptive immune system generates specific responses to target pathogens. Therefore, option D is NOT a component of the innate immune system, making it the correct answer in this question.

3. Which phrase best describes the relationship between smart grid technologies and renewable energy integration?

• A. Competitive and incompatible, hindering each other's effectiveness.
• B. Neutral and independent, neither impacting nor relying on each other.
• C. Complementary and synergistic, enhancing each other's functionality.
• D. Substitutable and interchangeable, offering equivalent solutions.

Correct answer: C

Rationale: The passage highlights the mutually beneficial relationship between smart grids and renewables, with both working together to optimize integration.

4. As a manager, she focuses her energy on both the quality of services rendered to the patients

• A. Country club management
• B. Organization man management
• C. Team management
• D. Authority-obedience management

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

5. What is the formula to calculate acceleration?

• A. Acceleration= Mass Force ​
• B. Acceleration= Force Mass ​
• C. Acceleration= Time Distance ​
• D. Acceleration= Time Change in Velocity ​

Correct answer: A

Rationale: Acceleration is calculated as the change in velocity divided by the time taken.

6. What is the relationship between work and the displacement of an object?

• A. Work depends only on the force applied, not displacement
• B. Work is directly proportional to displacement
• C. Work is inversely proportional to displacement
• D. Work is unrelated to displacement

Correct answer:

Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.
