1. What effect does doubling the net force applied to an object have on its acceleration, assuming mass remains constant?

• A. Acceleration doubles
• B. Acceleration is halved
• C. Acceleration remains the same
• D. Acceleration quadruples

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass remains constant and force doubles, acceleration also doubles.

2. Which of the following sentences uses the most formal language?

• A. The movie was awesome!
• B. The film did not meet my expectations.
• C. I found the cinematic experience to be unsatisfactory.
• D. The flick was pretty bad.

Correct answer: C

Rationale: The sentence uses more complex vocabulary ("cinematic experience") and avoids slang ("awesome," "flick").

3. Which of the following is a functional group commonly found in alcohols?

• A. Carbonyl
• B. Hydroxyl
• C. Amine
• D. Ester

Correct answer: B

Rationale: The hydroxyl functional group (OH) is commonly found in alcohols. The other choices are associated with different functional groups.

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. A kite has a top base of 20cm, a bottom base of 30cm, and two equal side lengths of 15cm. What is its perimeter?

• A. 55cm
• B. 65cm
• C. 70cm
• D. 80cm

Correct answer: C

Rationale: Add the lengths of all sides: perimeter = top base + bottom base + 2 * side length = 20cm + 30cm + 2 * 15cm = 70cm.

6. You need to paint a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m. Considering only the interior walls and floor (not the top), how much paint do you need (assume one can of paint covers 10 sq m)?

• A. 56 sq m
• B. 72 sq m
• C. 88 sq m
• D. 104 sq m

Correct answer: C

Rationale: Calculate the areas of each wall and the floor, sum them up, and subtract the area of the water surface (top). Divide the final area by the coverage area per can to determine the number of cans needed.
