1. A car is moving in a circle at constant speed. Which of the following is NOT true about its motion?
- A. It has a constant centripetal acceleration
- B. It has a constant tangential velocity
- C. It experiences a force directed towards the center of the circle
- D. It covers the same distance in equal time intervals along its circular path
Correct answer: B
Rationale: In circular motion at a constant speed, the car has a constant centripetal acceleration (choice A), experiences a force directed towards the center of the circle (choice C), and covers the same distance in equal time intervals along its circular path (choice D). However, the tangential velocity of an object in circular motion at a constant speed changes continuously as it moves around the circle, so it is not constant (choice B).
2. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.
- A. table
- B. leg
- C. ouch
- D. stubbed
Correct answer: C
Rationale: Interjections express emotions or sudden feelings. "Ouch" conveys a feeling of pain.
3. What is the term for a group of organisms with the same genetic makeup?
- A. Population
- B. Clone
- C. Genotype
- D. Species
Correct answer: B
Rationale: Rationale: - A population (option A) refers to a group of individuals of the same species living in the same area. - Genotype (option C) refers to the genetic makeup of an individual organism. - Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. This term specifically refers to organisms with the same genetic makeup, making it the most appropriate choice for the question.
4. Which word best synonyms with the word "elated"?
- A. Angry
- B. Sad
- C. Excited
- D. Confused
Correct answer: C
Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.
5. How does friction affect motion?
- A. Friction increases speed
- B. Friction decreases speed
- C. Friction has no impact on speed
- D. Friction causes objects to float
Correct answer: b
Rationale: Friction opposes motion, leading to a decrease in speed or hindering movement.
6. Which of the following is an example of a chemical property of matter?
- A. Boiling point
- B. Flammability
- C. Density
- D. Conductivity
Correct answer: b
Rationale: Chemical properties describe how a substance reacts with other substances, such as its ability to burn (flammability) or react with acids or bases.
