Physics

1. A water wave approaches a shallow beach. What happens to its speed, wavelength, and frequency?

Correct answer: B

Rationale: As waves enter shallow water, they slow down due to increased interaction with the bottom. This causes the wavelength to decrease to maintain the constant wave energy (E = hf). Frequency remains constant as it's determined by the source, not the medium.

2. Stephanie is often seen interacting with the medical intern during coffee breaks and after duty

Correct answer: B

Rationale: The correct answer is 'B: Informal.' Stephanie's interactions with the medical intern during coffee breaks and after duty suggest a casual and friendly relationship, rather than a formal or official one. 'Informal' describes interactions that are relaxed, personal, and not bound by strict professional protocols. In contrast, 'formal' interactions would involve more structured and official communication, such as meetings or professional discussions. 'Staff' and 'line' are not relevant in this context, as they do not describe the nature of the relationship between Stephanie and the medical intern.

3. The spleen, an organ associated with the lymphatic system, plays a crucial role in:

Correct answer: B

Rationale: The correct answer is B: 'Filtering blood and destroying old red blood cells.' The spleen is part of the lymphatic system and acts as a blood filter, removing old or damaged red blood cells and helping to fight infections. It does not play a role in regulating blood sugar levels (A), producing digestive enzymes (C), or secreting hormones (D). Understanding the function of the spleen in filtering blood and removing old red blood cells is crucial for grasping its role in maintaining overall health and immunity.

4. 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

5. What is the general formula for an alkyl halide?

Correct answer: C

Rationale: The general formula for an alkyl halide is \(C_nH_{2n-1}X\), where X represents a halogen (e.g., F, Cl, Br, I).

6. What is the molar mass of Ca(NO3)2?

Correct answer: b

Rationale: Calculate the molar mass: Ca(40.08) + 2N(14.01) + 6O(16.00) = 132.1 g/mol.
