physics

1. Which property of a wave determines its loudness in sound waves?

Correct answer: a

Rationale: Amplitude in sound waves relates to the loudness or intensity of the sound.

2. 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.

3. The unit for measuring luminous flux, which describes the perceived brightness of a light source by the human eye, is:

Correct answer: A

Rationale: The correct answer is B: Lumen. Luminous flux is the measure of the total quantity of visible light emitted by a source per unit time, measured in lumens. The candela (A) is the unit for luminous intensity, lux (C) is the unit for illuminance (luminous flux per unit area), and Hertz (D) is the unit for frequency. Therefore, in this question, the unit for measuring luminous flux is the lumen, as it specifically quantifies the perceived brightness of a light source by the human eye.

4. Which of the following is NOT true about fossils?

Correct answer: D

Rationale: Rationale: A) This statement is true. Fossils can provide evidence for the order of appearance of different species through the study of the fossil record. B) This statement is true. Fossils can be used to estimate the age of rocks and layers through relative dating methods such as stratigraphy and absolute dating methods like radiometric dating. C) This statement is true. Fossils can provide information about the behavior of extinct organisms through the study of their preserved remains and traces. D) This statement is NOT true. Fossils are not always perfectly preserved. In many cases, fossils are incomplete, fragmented, or altered over time due to geological processes. The level of preservation can vary depending on factors such as the type of organism, the environment in which it lived, and the processes involved in fossilization.

5. A car is accelerating down a hill. Which of the following forces is NOT acting on the car?

Correct answer: B

Rationale: Normal force from the road. The normal force acts perpendicular to the surface of contact and does not contribute to the acceleration down the hill.

6. Reactions requiring light energy to proceed are classified as:

Correct answer: C

Rationale: The correct answer is C: "Photochemical reactions." Photochemical reactions are a type of chemical reaction that requires light energy to proceed. During a photochemical reaction, light energy is absorbed by a substance, leading to changes in its chemical structure or properties. This process is different from combustion reactions (A), which involve the rapid combination of a fuel with oxygen to release heat and light energy. Endothermic reactions (B) absorb heat energy, not light energy, to proceed. Double displacement reactions (D) involve the exchange of ions between reactants, but do not specifically require light energy to occur. Therefore, the most appropriate classification for reactions requiring light energy is photochemical reactions.
