physics

1. Which property of a wave represents the distance between two successive identical points on a wave?

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. The process of a liquid changing into a gas is called:

Correct answer: A

Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.

3. The innate immune system provides a non-specific first line of defense. What are some physical barriers that contribute to the innate immune system?

Correct answer: C

Rationale: The correct answer is C: "Skin and mucous membranes." The innate immune system consists of physical barriers, such as the skin and mucous membranes, that act as the first line of defense against pathogens. These barriers prevent pathogens from entering the body and play a crucial role in protecting against infections. Antibodies (option A) are part of the adaptive immune response, not the innate immune system. Phagocytes (option B) are cells that engulf and destroy pathogens, which are part of the innate immune system. Memory B cells (option D) are specific to the adaptive immune response and are not considered part of the innate immunity that provides the initial, non-specific defense.

4. Which factor affects the kinetic energy of an object the most?

Correct answer:

Rationale: Kinetic energy is directly proportional to the square of an object's velocity.

5. Based on the information provided, which statement is LEAST likely to be supported by the author?

Correct answer: B

Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.

6. The number of protons in the nucleus of an atom determines its:

Correct answer: B

Rationale: The atomic number (Z) equals the number of protons in the nucleus and uniquely identifies an element. Mass number (A) includes both protons and neutrons, isotopes have different neutron numbers, and valence electrons are involved in bonding, not atomic identity.
