physics

1. What is the relationship between work, force, and displacement?

Correct answer: b

Rationale: Work done is the product of force and displacement in the direction of the force.

2. What property of a wave is measured in Hertz (Hz)?

Correct answer: d

Rationale: Frequency, the number of oscillations per second, is measured in Hertz (Hz).

3. What is the stoichiometric coefficient of nitrogen (N2) in the balanced equation for the Haber process: N2 + 3H2 → 2NH3?

Correct answer: a

Rationale: The coefficient of N2 is 1 in the balanced equation

4. What are the differences between RNA and DNA?

Correct answer: B

Rationale: Rationale: A) This statement is incorrect. RNA and DNA have different structures and functions. RNA is involved in protein synthesis and other cellular processes, while DNA stores genetic information. B) This statement is correct. RNA is typically single-stranded, while DNA is double-stranded, forming a double helix structure. C) This statement is correct. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. D) This statement is incorrect. RNA contains adenine, guanine, cytosine, and uracil, while DNA contains adenine, guanine, cytosine, and thymine.

5. What is the tough, fibrous tissue that connects bones at joints called?

Correct answer: B

Rationale: The correct answer is B: Ligaments. Ligaments are the tough, fibrous tissue that connects bones at joints. They provide stability and support to the joints, preventing excessive movement that could result in injury. Cartilage is a smooth, rubbery tissue that covers the ends of bones and cushions joints. Tendons are fibrous cords that attach muscles to bones, allowing for movement. Fascia is a connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, providing support and protection. Therefore, in this case, the term that specifically refers to the tissue connecting bones at joints is ligaments.

6. How is power related to energy?

Correct answer: b

Rationale: Energy is related to the amount of work done or the capacity to do work, while power measures the rate at which work is done or energy is transferred.
