TEAS Physics: Key Concepts for Exam Success

ATI TEAS 7

physics

1. What is the term for the distance between the center of a lens or curved mirror and its focal point?

A. Aperture
B. Focal length
C. Refractive index
D. Lens thickness

Correct answer:

Rationale: The focal length of a lens or curved mirror is the distance between its center and the focal point, where parallel light rays converge or appear to diverge from.

2. The phrase "survival of the fittest" refers to:

A. Organisms with the most complex anatomical structures are more likely to survive and reproduce.
B. Organisms that demonstrate the best adaptations to their environment have a higher chance of survival and reproduction.
C. All organisms have an equal probability of survival and reproductive success regardless of their traits.
D. Only the strongest and most aggressive individuals within a population will survive and reproduce.

Correct answer: B

Rationale: Rationale: The phrase "survival of the fittest" is often associated with the concept of natural selection, which was proposed by Charles Darwin. Natural selection is the process by which organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. This process does not necessarily favor the most complex anatomical structures (option A) or the strongest and most aggressive individuals (option D). Instead, it emphasizes the importance of adaptations that enhance an organism's ability to survive and reproduce in a specific environment. Option C is incorrect because natural selection results in differential reproductive success based on an organism's traits, meaning that not all organisms have an equal probability of survival and reproductive success.

3. In a single displacement reaction, one element takes the place of another element in a compound. Which of the following is an example?

A. 2H2 + O2 -> 2H2O
B. Zn + 2HCl -> ZnCl2 + H2
C. CaCO3 -> CaO + CO2
D. CH4 + 2O2 -> CO2 + 2H2O

Correct answer: B

Rationale: In a single displacement reaction, one element replaces another element in a compound. Option B, 'Zn + 2HCl -> ZnCl2 + H2,' is an example of a single displacement reaction where zinc (Zn) replaces hydrogen (H) in hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2). The other options do not involve one element displacing another in a compound. Option A is a synthesis reaction, option C is a decomposition reaction, and option D is a combustion reaction. Therefore, option B is the correct answer as it demonstrates the concept of single displacement reactions.

4. In technical writing, it's crucial to:

A. Use informal language to connect with the audience.
B. Emphasize your expertise with complex jargon.
C. Explain concepts clearly and concisely for diverse readers.
D. Prioritize creativity and artistic flair in your writing style.

Correct answer: C

Rationale: Technical writing aims to convey information accurately and understandably to various audiences, requiring clear and concise language.

5. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

A. Advise her staff to go on vacation.
B. Ignore her observations; it will be resolved even without intervention
C. Remind her to show loyalty to the institution.
D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.
