Physics

1. A prism separates white light into its constituent spectral components because:

Correct answer: B

Rationale: The correct answer is B because different colors experience varying speeds when passing through a prism due to their differing wavelengths. This causes them to refract at different angles, resulting in the separation of white light into its constituent spectral components. The phenomenon of dispersion occurs as a result of this wavelength-dependent refraction, allowing us to see the full spectrum of colors. Absorbing certain colors (option A) or reflecting specific colors (option D) would not explain how a prism separates white light. Additionally, if a prism were to bend all colors with the same magnitude (option C), it would not result in the distinct separation of colors that we observe.

2. What literary device is used in the phrase "a heart of gold"?

Correct answer: A

Rationale: The phrase directly compares someone's good nature to gold, making it a metaphor.

3. Classifications of human tissues exclude:

Correct answer: D

Rationale: The correct answer is D: 'Bony tissue.' Classifications of human tissues typically include four main types: epithelial, connective, muscular, and nervous tissue. Bony tissue, also known as osseous tissue, is a specialized form of connective tissue that forms bones in the skeletal system. While bony tissue is an essential component of the human body, it is not typically categorized separately as a distinct tissue type in general tissue classifications. Therefore, it is the exception from the list provided in the question, making it the correct answer.

4. What is the name for the mixture of reactants and products present during a chemical reaction?

Correct answer: C

Rationale: This mixture contains both the starting materials (reactants) and the newly formed substances (products) during the reaction process.

5. Which of the following is an example of a secondary alcohol?

Correct answer: C

Rationale: Isopropanol is an example of a secondary alcohol, as the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. The other choices are primary alcohols.

6. She knows that there are external forces that influence changes in his unit. Which of the

Correct answer: A

Rationale: The correct answer is option A: 'Memo from the CEO to cut down on electrical consumption.' This choice represents an external force that can influence changes in the unit by setting a directive from top management to reduce electricity usage, impacting operations and decisions within the unit. While options B, C, and D may also affect the unit to some extent, they are not as directly tied to external influences as the CEO's memo. The demands of the labor sector (option B) and low staff morale (option C) are internal factors, while regulatory and accreditation standards (option D) are more overarching guidelines rather than specific external forces impacting the unit. Therefore, the most direct and relevant external force in this scenario is the directive from the CEO, making option A the correct choice.
