1. Energy manifests in various forms. Which of the following is NOT considered a fundamental energy type?

• A. Thermal energy
• B. Momentum
• C. Sound energy
• D. Chemical energy

Correct answer: B

Rationale: The correct answer is B. Momentum is not considered a form of energy; it is a property of moving objects. Thermal, sound, and chemical energy are all forms of energy. Thermal energy is the energy associated with the movement of particles within an object. Sound energy is produced by vibrations and travels through materials as waves. Chemical energy is stored within the bonds of chemical compounds. While momentum is a crucial concept in physics, it is not a fundamental form of energy.

2. Which rainforest plant has more than one use?

• A. The Buruti plant
• B. The Banana tree
• C. The Cinnamon tree
• D. The Coconut tree

Correct answer: A

Rationale: The correct answer is the Buruti plant. The passage mentions that Amazonian Indians use the fruit and stem of the Buruti plant for various purposes, such as a drink, making bread, and building houses. The other choices, Banana tree, Cinnamon tree, and Coconut tree, are not specifically mentioned as having multiple uses in the passage. While the passage does mention that bananas and coconuts are available as food in the rainforest, it does not specify multiple uses for these plants as it does for the Buruti plant.

3. Which word is NOT CORRECT? The student did not recognize which backpack was hers.

• A. Backpack
• B. Student
• C. Hers
• D. Recognize

Correct answer: C

Rationale: The correct answer is 'C: Hers.' The possessive pronoun 'hers' does not require an apostrophe. The use of 'her's' with an apostrophe is grammatically incorrect. Choices A, B, and D ('Backpack,' 'Student,' and 'Recognize') are all spelled correctly and are grammatically sound in the sentence provided.

4. What is the meaning of NEBULOUS?

• A. Clear
• B. Vague
• C. Precise
• D. Obvious

Correct answer: B

Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.

5. A pitcher throws a 45-g baseball at a velocity of 42 meters per second. What is the ball’s momentum?

• A. 0.189 kg⋅m/s
• B. 1.89 kg⋅m/s
• C. 1.07 kg⋅m/s
• D. 0.93 kg⋅m/s

Correct answer: B

Rationale: Momentum is calculated by multiplying mass (in kg) by velocity (in m/s). The mass of the baseball is 0.045 kg (45 grams converted to kg), and the velocity is 42 m/s. Momentum = 0.045 kg × 42 m/s = 1.89 kg⋅m/s. Therefore, the correct answer is 1.89 kg⋅m/s. Choice A is incorrect as it incorrectly converts the mass from grams to kg. Choice C and D are incorrect due to calculation errors.
