Chemistry
1. ch element shares the same group (family) on the periodic table with helium (He)?
- A. Neon (Ne)
- B. Boron (B)
- C. Carbon (C)
- D. Oxygen (O)
Correct answer: A
Rationale: Elements within the same group share similar electron configurations in their outermost shells, resulting in comparable chemical properties. Helium and Neon both belong to Group 18 (Noble Gases), explaining their similarities.
2. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?
- A. 4:00 PM
- B. 6:00 PM
- C. 8:00 PM
- D. 10:00 PM
Correct answer: B
Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.
3. Which property of matter refers to the measure of the force of gravity acting on an object?
- A. Mass
- B. Weight
- C. Density
- D. Volume
Correct answer: b
Rationale: Weight is the measure of the force of gravity acting on an object. It is calculated as mass multiplied by the acceleration due to gravity.
4. Which sentence uses strong verbs to create a more vivid image?
- A. The car moved slowly down the street.
- B. The car drove sluggishly down the road.
- C. The car inched down the avenue.
- D. The car traveled down the thoroughfare.
Correct answer: C
Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."
5. What is the principle behind optical fibers used in communication?
- A. Reflection of light within the fiber
- B. Refraction of light due to different densities within the fiber
- C. Total internal reflection guiding light through the fiber core
- D. Diffraction of light around bends in the fiber
Correct answer: C
Rationale: Optical fibers used in communication rely on the principle of total internal reflection guiding light through the fiber core. When light enters the fiber at a certain angle, it reflects off the boundary between the core and cladding, ensuring that the light remains trapped within the core and travels along the fiber without significant loss of signal. This total internal reflection allows for efficient transmission of light signals over long distances in optical communication systems.
6. What is the name of the muscle responsible for pumping blood throughout the body?
- A. Bicep
- B. Tricep
- C. Deltoid
- D. Cardiac muscle
Correct answer: D
Rationale: The correct answer is D: Cardiac muscle. The cardiac muscle, also known as the heart muscle, is responsible for pumping blood throughout the body. Unlike voluntary muscles like the bicep, tricep, and deltoid, the cardiac muscle is involuntary and works continuously to pump blood to all parts of the body. It is crucial for maintaining circulation and delivering oxygen and nutrients to tissues. Understanding the role of the cardiac muscle in the circulatory system is essential for grasping the importance of heart health and overall well-being.
