physics
1. Which of the following is an example of static friction?
- A. Sliding a heavy box across the floor
- B. A car moving around a curve
- C. Pushing a stationary object
- D. Braking a car to stop
Correct answer: c
Rationale: Static friction occurs when an object is at rest and prevents it from moving when a force is applied.
2. What term describes the bending of waves around obstacles or through openings?
- A. Reflection
- B. Refraction
- C. Diffraction
- D. Absorption
Correct answer: c
Rationale: Diffraction occurs when waves bend around obstacles or spread after passing through small openings.
3. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?
- A. Human papillomavirus (HPV)
- B. Chlamydia
- C. Gonorrhea
- D. Syphilis
Correct answer: D
Rationale: The correct answer is D: Syphilis. Syphilis is a sexually transmitted infection that can potentially cause infertility in both men and women if left untreated. In men, untreated syphilis can lead to damage to the testicles and epididymis, affecting sperm production. In women, syphilis can result in pelvic inflammatory disease (PID) which can lead to scarring and blockages in the fallopian tubes, causing infertility. While other STIs like chlamydia and gonorrhea can also lead to infertility if left untreated, syphilis is particularly known for its severe impact on reproductive health in both genders.
4. Which of the following is NOT a type of intermolecular force?
- A. Hydrogen bonding
- B. Dipole-dipole interactions
- C. Ionic bonding
- D. London dispersion forces
Correct answer: C
Rationale: Ionic bonding is a type of intramolecular force, holding ions together within an ionic compound. Intermolecular forces are responsible for the interactions between individual molecules.
5. Which group of elements is known for their reactivity and ability to form strong bonds with other elements?
- A. Noble gases
- B. Halogens
- C. Alkali metals
- D. Transition metals
Correct answer: B
Rationale: Rationale: Halogens are a group of elements in the periodic table that are known for their high reactivity and ability to form strong bonds with other elements. They have seven valence electrons, which makes them highly reactive as they only need one more electron to achieve a stable electron configuration. Halogens readily form compounds with other elements by gaining an electron to achieve a full outer shell, resulting in the formation of strong covalent bonds. In contrast, noble gases (option A) are known for their inertness and stable electron configurations, alkali metals (option C) are highly reactive but not as strong bond formers as halogens, and transition metals (option D) are known for their variable oxidation states and ability to form complex ions but are not as reactive as halogens in terms of bond formation.
6. 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
