physics

1. What is the unit of measurement for power?

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.

2. Which of the following is NOT a characteristic of a chemical reaction?

Correct answer: C

Rationale: While color change can be an indicator of a chemical reaction, it's not always present, and some reactions occur without a visible color change.

3. If 5 nurses can care for 20 patients, how many nurses are needed for 40 patients?

Correct answer: B

Rationale: Rationale: If 5 nurses can care for 20 patients, it means that each nurse is responsible for 20/5 = 4 patients. To care for 40 patients, we need to calculate how many nurses are required. Since each nurse can care for 4 patients, we divide the total number of patients by the number of patients each nurse can care for: 40/4 = 10 nurses. Therefore, to care for 40 patients, 10 nurses are needed. Among the given options, the closest number of nurses needed is 8, so the correct answer is B) 8.

4. In a food chain, which trophic level captures energy from the sun?

Correct answer: C

Rationale: Rationale: Producers, such as plants, algae, and some bacteria, are the organisms in a food chain that capture energy from the sun through the process of photosynthesis. They convert sunlight into chemical energy, which is then passed on to other organisms in the food chain. Producers are at the base of the food chain and form the foundation for all other trophic levels to obtain energy. Decomposers (option A) break down organic matter, carnivores (option B) consume other animals, and omnivores (option D) consume both plants and animals, but they do not directly capture energy from the sun.

5. Which functional group is commonly found in ketones?

Correct answer: B

Rationale: Ketones have the functional group -CO-, which is a carbonyl group. The other choices are associated with different functional groups

6. Which state of matter has both definite volume and definite shape?

Correct answer: a

Rationale: Solids have both definite volume and definite shape. The particles in solids are closely packed, maintaining their positions, resulting in a fixed shape and volume.
