Physics

1. What is the acceleration of an object moving at a constant speed of 20 m/s if it comes to a complete stop within 5 seconds?

Correct answer: C

Rationale: The acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 0 m/s (as the object comes to a complete stop), the initial velocity is 20 m/s, and the time taken is 5 seconds. Plugging these values into the formula, we get acceleration = (0 m/s - 20 m/s) / 5 s = -20 m/s / 5 s = -4 m/s². Therefore, the acceleration is -4 m/s².

2. Which of the following substances is typically a good conductor of electricity when dissolved in water?

Correct answer: b

Rationale: Ionic compounds like sodium chloride dissociate into ions in water, making the solution conductive. The other choices do not typically conduct electricity in water.

3. What is the name of the tough, fibrous connective tissue that attaches muscle to bone?

Correct answer: C

Rationale: The correct answer is C: Tendon. A tendon is the tough, fibrous connective tissue that attaches muscle to bone. Fascia (A) is a connective tissue that surrounds muscles, while perimysium (B) is the connective tissue surrounding bundles of muscle fibers. Ligaments (D) are tough bands of tissue that connect bones to other bones. Understanding the function and structure of tendons is crucial for biomechanics and movement as they play a vital role in transmitting forces from muscles to bones, allowing for movement and stability in the body.

4. The author expresses concern about the...

Correct answer: B

Rationale: The passage's focus on managing the intermittency of renewable energy due to weather conditions implies concern about B.

5. During embryonic development, most vertebrates exhibit structures called pharyngeal pouches. These pouches eventually develop into different structures in various vertebrate groups, such as the human jaw and inner ear. Pharyngeal pouches are an example of:

Correct answer: B

Rationale: Rationale: Pharyngeal pouches in vertebrates are an example of homologous structures because they share a common evolutionary origin. Despite developing into different structures in various vertebrate groups, such as the jaw and inner ear in humans, these structures originated from the same ancestral feature. This concept of homology highlights the evolutionary relationship between different species and how structures can be modified over time to serve different functions while retaining a common origin.

6. What is the main topic of the passage?

Correct answer: B

Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.
