physics

1. Which of the following best describes a balanced force acting on an object?

Correct answer: b

Rationale: When balanced forces act on an object, the object remains in a state of constant velocity (including at rest).

2. How does an increase in surface area affect the force of friction between two surfaces?

Correct answer: b

Rationale: Increasing surface area reduces the force per unit area, decreasing friction.

3. The phrase "echo chambers" refers to

Correct answer: C

Rationale: Echo chambers occur when individuals primarily encounter information that confirms their existing biases, potentially limiting their exposure to alternative perspectives.

4. In the reaction 2Na + 2H2O → 2NaOH + H2, what is the limiting reactant when 3 moles of sodium react with 2 moles of water?

Correct answer: a

Rationale: Sodium is the limiting reactant because it runs out first in a 1:1 ratio with water.

5. What is the process by which the body reabsorbs water from the large intestine?

Correct answer: B

Rationale: Rationale: - Dehydration (Option A) refers to the condition of having insufficient water in the body, not the process of water reabsorption in the large intestine. - Osmosis (Option B) is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In the large intestine, water is reabsorbed through osmosis to maintain the body's fluid balance. - Filtration (Option C) is a process where a liquid or gas passes through a filter to separate the components. It is not the primary mechanism for water reabsorption in the large intestine. - Secretion (Option D) is the release of substances from cells, but it is not the process by which the body reabsorbs water from the large intestine. Therefore, the correct process by which the body reabsorbs water from the large intestine is

6. The term that refers to the specific role and position an organism occupies within an ecosystem is called a:

Correct answer: B

Rationale: Rationale: A) Habitat refers to the specific physical environment where an organism lives, including the biotic and abiotic factors present. While the habitat is important for an organism's survival, it does not encompass the specific role and interactions of the organism within the ecosystem. B) Niche refers to the specific role and position an organism occupies within an ecosystem, including its interactions with other organisms and its physical environment. This includes the organism's feeding habits, behavior, preferred habitat, and how it obtains resources. The niche of an organism is crucial in determining its impact on the ecosystem and its relationships with other species. C) Population refers to a group of individuals of the same species living in a specific area and interacting with each other. While populations play a role in ecosystems, they do not specifically describe the role and position of an individual organism within the ecosystem. D) Biome refers to a large geog
