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).
