Physics

1. Nuclear forces are much stronger than electromagnetic forces at the nuclear level. What property best describes this characteristic?

Correct answer: A

Rationale: Nuclear forces operate within a very small range compared to electromagnetic forces, impacting only nucleons directly touching each other.

2. How does the amplitude of a wave relate to its intensity or loudness?

Correct answer: B

Rationale: Higher amplitude corresponds to larger displacement from equilibrium and translates to higher intensity or perceived loudness in sound waves.

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. The term "goiter" refers to a condition characterized by:

Correct answer: B

Rationale: The term 'goiter' specifically refers to the abnormal enlargement of the thyroid gland. This can be due to various reasons such as iodine deficiency, Hashimoto's thyroiditis, or Graves' disease. Options A, C, and D are incorrect as they describe conditions related to other glands and hormones in the endocrine system. It is important to differentiate between different endocrine disorders to accurately diagnose and treat patients. Therefore, the correct answer is B, as a goiter is characterized by the excessive growth of the thyroid gland.

5. Which component of the nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles?

Correct answer: c

Rationale: The correct answer is C, the somatic nervous system. The somatic nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles. This system consists of motor neurons that send signals from the central nervous system to the skeletal muscles, allowing us to consciously control our movements. The autonomic nervous system (A) controls involuntary actions like heart rate and digestion, the peripheral nervous system (B) includes all nerves outside of the brain and spinal cord, and the sympathetic nervous system (D) is a division of the autonomic nervous system responsible for the fight-or-flight response. Therefore, the somatic nervous system is specifically involved in voluntary movements.

6. A rocket blasts off from Earth. What is the main force propelling the rocket upwards?

Correct answer: C

Rationale: Thrust from the rocket engine. This force is produced by the action-reaction principle and pushes the rocket upwards against the exhaust gases.
