Physics
1. What is the difference between a real image and a virtual image formed by a lens?
- A. Real images can be projected onto a screen, while virtual images cannot.
- B. Real images are always upright, while virtual images can be inverted.
- C. Real images are formed by converging lenses, while virtual images are formed by diverging lenses.
- D. All of the above are true.
Correct answer: A
Rationale: Real images are formed by the actual convergence of light rays and can be projected onto a screen, while virtual images are formed by the apparent divergence of light rays and cannot be projected.
2. Which structure connects a muscle to a bone, allowing movement to occur at a joint?
- A. Tendon
- B. Ligament
- C. Cartilage
- D. Bursa
Correct answer: a
Rationale: The correct answer is A: Tendon. Tendons are fibrous connective tissues that connect muscles to bones. They play a crucial role in allowing movement to occur at joints by transmitting the force generated by the muscle to the bone, resulting in movement. Ligaments (option B) connect bone to bone, providing stability to joints. Cartilage (option C) is a smooth, flexible tissue that covers the ends of bones and acts as a cushion. Bursa (option D) is a small fluid-filled sac that reduces friction between tissues. Therefore, tendons are specifically designed to connect muscles to bones for movement at joints.
3. What is the meaning of the idiom "to bite off more than one can chew"?
- A. To be overly confident
- B. To take on more than one can handle
- C. To be easily discouraged
- D. To be meticulous in planning
Correct answer: B
Rationale: The idiom warns against undertaking a task exceeding one's capabilities.
4. The final sentence highlights the need for
- A. Public funding for scientific research and development of climate-friendly technologies.
- B. Individual lifestyle changes and responsible consumption habits to reduce carbon footprints.
- C. International partnerships and collaborative efforts to implement effective climate action plans.
- D. Educational campaigns raising awareness about the urgency of addressing climate change.
Correct answer: C
Rationale: The emphasis on "international cooperation," "robust scientific research," and "adapting" suggests a focus on collaborative and multi-faceted solutions, aligning with C.
5. Two objects with different masses collide. What happens to their momentum after the collision?
- A. Increases for both objects
- B. Decreases for both objects
- C. Remains the same for both objects
- D. Can increase for one and decrease for the other
Correct answer: C
Rationale: In an isolated system (no external forces), the total momentum
6. Which of the following is NOT a route of transmission for a sexually transmitted infection (STI)?
- A. Unprotected sexual contact
- B. Sharing contaminated needles
- C. Deep kissing
- D. Mother to child during childbirth
Correct answer: C
Rationale: Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.
