physics

1. What happens to the wavelength of a wave when its frequency increases while the speed remains constant?

Correct answer: b

Rationale: When the frequency of a wave increases while the speed remains constant, the wavelength decreases.

2. Which of the following terms refers to the degeneration of nerve tissue?

Correct answer: B

Rationale: The correct answer is B: 'Demyelination.' Demyelination is the term used to describe the degeneration of the myelin sheath, the protective covering of nerve fibers. This process can lead to impaired nerve signal transmission and potential nerve damage. 'Potentiation' refers to the strengthening of neural connections, 'Reuptake' is the reabsorption of neurotransmitters by the presynaptic neuron, and 'Neurogenesis' is the generation of new nerve cells. In this context, demyelination is the most appropriate term related to nerve tissue degeneration.

3. Which of the following sentences uses figurative language?

Correct answer: B

Rationale: This sentence uses a simile, comparing the child's speed to a cheetah's.

4. Which property of a substance refers to the force exerted on an object due to gravity?

Correct answer:

Rationale: Weight is the measure of the force exerted on an object due to gravity. It is calculated as mass multiplied by the acceleration due to gravity.

5. Which statement best summarizes the main argument of the passage?

Correct answer: C

Rationale: The passage acknowledges both the potential and concerns surrounding smart cities, making it the most accurate summary.

6. Which part of the respiratory system is responsible for gas exchange between the blood and inhaled air?

Correct answer: C

Rationale: The correct answer is C, 'Alveoli.' The alveoli are tiny air sacs located at the end of the bronchioles in the lungs where gas exchange occurs. Oxygen from the inhaled air diffuses through the thin walls of the alveoli and into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The trachea (A) is the windpipe that carries air to and from the lungs; the larynx (B) contains the vocal cords and helps with swallowing; and the pharynx (D) is the part of the throat that connects the mouth and nasal cavity to the esophagus and trachea, but it is not directly involved in gas exchange.
