physics

1. What is the relationship between work, force, and displacement?

Correct answer: b

Rationale: Work done is the product of force and displacement in the direction of the force.

2. Two experiments investigating the same phenomenon produce conflicting results. What is the most appropriate next step?

Correct answer: C

Rationale: When faced with conflicting results from two experiments, it is important to critically evaluate the methodology of both experiments. By examining the experimental design, variables controlled for, sample sizes, and potential sources of bias, one can better understand the reasons behind the discrepancies. Attacking the methodology of the experiment with conflicting results can help identify potential flaws or limitations that may explain the differences in outcomes. This approach allows for a more informed decision on how to proceed, rather than simply ignoring or accepting one set of results over the other.

3. What can be inferred about the data collected by smart cities?

Correct answer: C

Rationale: The passage specifically mentions concerns about data privacy, implying potential issues for individuals.

4. When light reflects from a surface, what determines the angle of reflection?

Correct answer: C

Rationale: The angle of reflection is always equal to the angle of incidence according to the law of reflection, regardless of the material, wavelength, or intensity.

5. What is the term for an organism with two different alleles for a gene?

Correct answer: B

Rationale: An organism with two different alleles for a gene has a mixed genotype and may exhibit either the dominant or recessive trait depending on the specific gene and its alleles.

6. Lymph nodes are small, bean-shaped structures found along lymphatic vessels. What is their primary function?

Correct answer: C

Rationale: The correct answer is C. Lymph nodes are crucial components of the immune system. Their primary function is to filter lymph, which is a clear fluid containing white blood cells, and to fight off infections. Lymph nodes contain specialized cells that help trap and destroy pathogens, such as bacteria and viruses, that may be present in the lymph fluid. This process helps to prevent the spread of infections throughout the body and plays a key role in maintaining overall immune function. Therefore, option C, 'To filter lymph and fight infection,' is the most appropriate description of the primary function of lymph nodes.
