Physics

1. A car is accelerating down a hill. Which of the following forces is NOT acting on the car?

Correct answer: B

Rationale: Normal force from the road. The normal force acts perpendicular to the surface of contact and does not contribute to the acceleration down the hill.

2. What is the functional group present in amines?

Correct answer: C

Rationale: Amines have the functional group -NHâ‚‚. The other choices are associated with different functional groups.

3. The patella, commonly known as the kneecap, is an example of a:

Correct answer: A

Rationale: The patella, or kneecap, is a sesamoid bone. Sesamoid bones are small bones that develop within tendons, typically where they pass over joints. The patella functions to protect the knee joint and enhance the leverage of the quadriceps muscle. Its location and function align with those of a sesamoid bone, making option A the correct choice. Long bones, such as the femur, are characterized by their elongated shape and serve as levers for movement. Short bones, like those in the wrist and ankle, provide support and stability. Irregular bones, such as the vertebrae, have complex shapes and functions. Therefore, option A is the most appropriate answer in this context.

4. Which element is used in jewelry due to its malleability and resistance to tarnish?

Correct answer: C

Rationale: Gold's properties make it ideal for crafting durable and aesthetically pleasing jewelry

5. How does the amplitude of a wave relate to its intensity or loudness?

Correct answer: B

Rationale: Higher amplitude corresponds to larger displacement from equilibrium and translates to higher intensity or perceived loudness in sound waves.

6. What potential consequences can chromosomal nondisjunction have on offspring?

Correct answer: D

Rationale: Rationale: - Chromosomal nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to an abnormal number of chromosomes in the resulting cells. - Down syndrome is caused by an extra copy of chromosome 21, resulting from nondisjunction during meiosis. Individuals with Down syndrome have three copies of chromosome 21 instead of the usual two. - Turner syndrome is characterized by the absence of one X chromosome in females, leading to a variety of physical and developmental features. - Klinefelter syndrome features one or more extra X chromosomes in males, typically resulting in infertility and other physical characteristics. Therefore, chromosomal nondisjunction can lead to various genetic disorders such as Down syndrome, Turner syndrome, and Klinefelter syndrome, making option D the correct answer.
