1. What happens to the force of gravity between two objects when the distance between them is doubled?
- A. ) The force increases by a factor of 2
- B. The force increases by a factor of 4
- C. The force decreases by a factor of 2
- D. The force decreases by a factor of 4
Correct answer: d
Rationale: According to the inverse square law of gravity, the force of gravity decreases by a factor of 4 when the distance between two objects is doubled.
2. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."
- A. "My biggest fear"
- B. "that I wouldn't live life to the fullest"

- A. Solubility
- B. Miscibility
- C. Immiscibility
- D. Reactivity
Correct answer: A
Rationale: Solubility refers to the extent to which one substance can dissolve in another to form a homogeneous solution.
4. If the mass of an object remains constant and its velocity doubles, how does its momentum change?
- A. Momentum doubles
- B. Momentum halves
- C. Momentum quadruples
- D. Momentum remains the same
Correct answer: a
Rationale: Momentum is directly proportional to velocity when mass is constant.
5. Which of the following is a weak acid commonly found in citrus fruits?
- A. Sulfuric acid (Hâ‚‚SOâ‚„)
- B. Hydrochloric acid (HCl)
- C. Citric acid
- D. Nitric acid (HNO₃)
Correct answer: c
Rationale: Citric acid is a weak acid commonly found in citrus fruits. The other choices are strong acids.
6. Which of the following numbers is the greatest common factor (GCF) of 12 and 18?
- A. 2
- B. 3
- C. 6
- D. 9
Correct answer: C
Rationale: The GCF is the largest number that is a factor of both 12 and 18. We can factor each number to find common factors: 12 = 2 x 2 x 3 and 18 = 2 x 3 x 3. The greatest common factor that appears in both factorizations is 6 (2 x 3).
