1. What is the relationship between work and energy?

• A. Work is the rate of energy transfer
• B. Work and energy are the same concepts
• C. Work is the result of energy
• D. Work changes an object's energy from one form to another

Correct answer: d

Rationale: Work is the process that changes an object's energy from one form to another or transfers it from one object to another.

2. Which of the following is a unit of power?

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

Correct answer: c

Rationale: Watt is the unit of power, measuring the rate of work done or energy transfer.

3. Identify the type of clause in the sentence "When the clock struck midnight, the magic began."

• A. Main clause
• B. Subordinate clause
• C. Appositive clause
• D. Noun clause

Correct answer: B

Rationale: The "when" clause introduces additional information about the main sentence and acts as a subordinate clause.

5. What happens to the potential energy of an object as it falls freely near the Earth's surface?

• A. Potential energy decreases
• B. Potential energy increases
• C. Potential energy remains constant
• D. Potential energy becomes zero

Correct answer: a

Rationale: As an object falls freely, its potential energy due to gravity decreases as it gets closer to the Earth's surface.

6. The control center of the cell, containing genetic information (DNA), is the:

• A. Golgi apparatus
• B. Ribosome
• C. Nucleus
• D. Endoplasmic reticulum

Correct answer: C

Rationale: The correct answer is C: Nucleus. The nucleus is the control center of the cell as it contains the cell's genetic material, DNA. It acts as the brain of the cell, regulating gene expression and controlling cell activities. The Golgi apparatus is responsible for packaging and processing proteins, the ribosomes are involved in protein synthesis, and the endoplasmic reticulum is essential for protein and lipid synthesis. However, none of these organelles house the genetic information of the cell, making the nucleus the correct answer in this case.
