1. Which type of energy is possessed by an object in motion?

• A. Potential energy
• B. Kinetic energy
• C. Thermal energy
• D. Chemical energy

Correct answer: b

Rationale: Kinetic energy is the energy possessed by an object in motion.

2. Frequent, painful urination is a common symptom of:

• A. Diabetes
• B. Urinary tract infection (UTI)
• C. Kidney stones
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Frequent, painful urination can be a symptom of various conditions affecting the urinary system. In diabetes, high blood sugar levels can lead to increased urine production. UTIs often cause painful urination due to the infection in the urinary tract. Kidney stones can also result in frequent and painful urination as they obstruct the flow of urine. Therefore, all three options can present with the common symptom of frequent, painful urination, making 'All of the above' the correct choice.

3. What happens to the wavelength of a wave when its frequency increases while the speed remains constant?

• A. Wavelength increases
• B. Wavelength decreases
• C. Wavelength remains the same
• D. Wavelength becomes zero

Correct answer: b

Rationale: When the frequency of a wave increases while the speed remains constant, the wavelength decreases.

4. Which of the following types of muscle tissue is found attached to bones and allows for voluntary movement?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Connective tissue

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is the type of muscle tissue that is attached to bones and allows for voluntary movement. This type of muscle is under conscious control, meaning we can choose to contract or relax these muscles to produce movement. Smooth muscle (option A) is found in the walls of internal organs and is not under voluntary control. Cardiac muscle (option B) is found in the heart and also functions involuntarily. Connective tissue (option D) primarily provides support and structure to the body but does not directly enable movement like skeletal muscle does.

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

• A. Sensory and motor
• B. Sympathetic and parasympathetic
• C. Myelinated and unmyelinated
• D. Central and peripheral

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.

6. What is the momentum of a car with a mass of 1500 kg moving at a speed of 20 m/s?

• A. 30,000 kg m/s
• B. 1500 kg m/s
• C. 20 kg m/s
• D. Momentum cannot be determined without knowing the direction of motion.

Correct answer: A

Rationale: Momentum is defined as the product of mass and velocity. Momentum = mass x velocity = 1500 kg x 20 m/s = 30,000 kg m/s.
