physics
1. What is the law of conservation of energy?
- A. Energy cannot be created, only destroyed
- B. Energy can be created but not destroyed
- C. Energy can neither be created nor destroyed, only transformed from one form to another
- D. Energy is always created in any process
Correct answer:
Rationale: According to the law of conservation of energy, the total energy in a closed system remains constant; it can change forms but cannot be created or destroyed.
2. What is the breakdown product of ATP (adenosine triphosphate) that provides energy for muscle contraction?
- A. Glucose
- B. Creatine phosphate
- C. ADP (adenosine diphosphate)
- D. Lactic acid
Correct answer: C
Rationale: The correct answer is C: ADP (adenosine diphosphate). During muscle contraction, ATP is broken down into ADP and inorganic phosphate, releasing energy that fuels the muscle contraction process. This energy release allows the muscle fibers to contract and perform work. Glucose is a source of energy that is broken down through cellular respiration to produce ATP but is not the direct breakdown product of ATP itself. Creatine phosphate is another energy storage molecule in muscles but is not the breakdown product of ATP. Lactic acid is produced during anaerobic respiration when there is a lack of oxygen, and it is not the primary energy source for muscle contraction. Therefore, ADP is the correct breakdown product of ATP that provides energy for muscle contraction.
3. When she presents the nursing procedures to be followed, she refers to what type of
- A. Process
- B. Outcome
- C. Structure
- D. Criteria
Correct answer: D
Rationale: In this scenario, the person is referring to the specific standards or benchmarks that must be met when presenting nursing procedures, which aligns with the definition of 'criteria'. Criteria are the established principles or requirements that serve as a reference point for evaluation or judgment. It is essential for healthcare professionals to adhere to specific criteria when performing procedures to ensure quality care. The other options, such as 'process', 'outcome', and 'structure', do not directly relate to the standards or benchmarks being referenced in this context.
4. What happens to the density of a gas when its temperature increases at constant pressure?
- A. It increases.
- B. It decreases.
- C. It remains the same.
- D. Information insufficient
Correct answer: B
Rationale: As gas particles gain thermal energy with increasing temperature, they spread out, decreasing the density.
5. Which cartilage type allows for smooth movement at joints and absorbs shock?
- A. Hyaline cartilage
- B. Fibrocartilage
- C. Elastic cartilage
- D. None of the above
Correct answer: A
Rationale: The correct answer is A: Hyaline cartilage. Hyaline cartilage is the most abundant type of cartilage in the body and is found in the joints, providing a smooth surface for movement. It also acts as a shock absorber, cushioning the joints during activities. Fibrocartilage is found in intervertebral discs and provides strength and support, but it is not as effective at absorbing shock as hyaline cartilage. Elastic cartilage is found in the external ear and epiglottis, providing flexibility and maintaining shape, but it does not have the same shock-absorbing properties as hyaline cartilage. Therefore, hyaline cartilage is the best choice for a cartilage type that allows for smooth movement at joints and absorbs shock.
6. What type of figurative language is used in the statement "Her laughter was music to my ears"?
- A. Metaphor
- B. Simile
- C. Hyperbole
- D. Personification
Correct answer: A
Rationale: The statement directly compares laughter to music, forming a metaphor.
