physics

1. What term describes the phenomenon of two waves canceling each other out when they meet?

Correct answer: C

Rationale: Destructive interference occurs when two waves meet and their amplitudes are such that they cancel each other out, resulting in a wave with a smaller amplitude or no wave at all. This is in contrast to constructive interference, where two waves combine to produce a wave with a larger amplitude. Refraction and diffraction are phenomena related to the bending of waves as they pass through different mediums or obstacles, respectively.

2. Which of the following is the neutral subatomic particle found in the nucleus of an atom?

Correct answer: C

Rationale: Neutrons are subatomic particles found in the nucleus of an atom that have no charge. They have a mass of approximately 1 atomic mass unit (amu). The number of neutrons in an atom's nucleus contributes to the mass number of the atom, which is the total number of protons and neutrons in the nucleus.

3. Diabetic nephropathy, a complication of diabetes, affects the:

Correct answer: D

Rationale: The correct answer is D: Nephrons. Diabetic nephropathy is a type of kidney disease that occurs as a complication of diabetes. It specifically affects the nephrons, which are the functional units of the kidneys responsible for filtering waste and excess fluids from the blood to produce urine. Damage to the nephrons can lead to kidney failure and other serious complications in individuals with diabetes. Therefore, understanding the impact of diabetes on the nephrons is crucial for managing diabetic nephropathy effectively.

4. Where does bile, a substance that helps digest fats, come from?

Correct answer: C

Rationale: Rationale: Bile is a substance that helps digest fats by emulsifying them, which means breaking down large fat globules into smaller droplets to increase the efficiency of fat digestion by enzymes. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to aid in the digestion and absorption of fats. The stomach (option A) is responsible for the initial digestion of food through the action of gastric juices, but bile is not produced in the stomach. The pancreas (option B) secretes digestive enzymes such as lipase to further break down fats in the small intestine, but it does not produce bile. The gallbladder (option D) stores and concentrates bile produced by the liver but does not actually produce bile itself.

5. What is the difference between a real image and a virtual image formed by a lens?

Correct answer: A

Rationale: Real images are formed by the actual convergence of light rays and can be projected onto a screen, while virtual images are formed by the apparent divergence of light rays and cannot be projected.

6. After discussing the possible effects of the low patient satisfaction rate, the staff started to list

Correct answer: B

Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.
