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. The peripheral nervous system can be further divided into which two main parts?

Correct answer: A

Rationale: The correct answer is A: 'Sensory and motor.' The peripheral nervous system is divided into two main parts based on their functions. The sensory division (afferent) transmits sensory information from receptors to the central nervous system, while the motor division (efferent) transmits signals from the central nervous system to muscles and glands to produce a response. Options B, C, and D are incorrect as they do not accurately describe the main divisions of the peripheral nervous system. Understanding this division is crucial in comprehending how information is processed and responses are generated in the body.

3. Which of the following is a common property of both acids and bases?

Correct answer: d

Rationale: Both acids and bases conduct electricity when dissolved in water. The other choices are specific to either acids or bases.

4. Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.

Correct answer: C

Rationale: Strong nuclear force. This incredibly powerful force overcomes the repulsive electrostatic force between protons and binds the nucleus together.

5. Which of the following is the main organ responsible for regulating sleep?

Correct answer: B

Rationale: Rationale: The hypothalamus is the main organ responsible for regulating sleep. It plays a crucial role in controlling the body's circadian rhythm, which is the internal clock that regulates the sleep-wake cycle. The hypothalamus receives input from the eyes about light and darkness, which helps in determining when it is time to sleep or wake up. It also regulates the production of melatonin by the pineal gland, which is a hormone that helps control sleep patterns. While the thalamus is involved in relaying sensory information to the brain, the pituitary gland is responsible for producing and releasing hormones, and the pineal gland produces melatonin under the control of the hypothalamus.

6. Which preposition best completes the sentence: "She borrowed money _____ her friend."
