physics
1. What is the relationship between mass and inertia?
- A. Mass is a measure of inertia
- B. Mass has no relation to inertia
- C. Inertia is a measure of weight
- D. Inertia increases with decreasing mass
Correct answer: a
Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.
2. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?
- A. Frequency decreases
- B. Frequency increases
- C. Frequency remains constant
- D. Frequency becomes zero
Correct answer: b
Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.
3. What type of energy is possessed by an object due to its position or configuration?
- A. Kinetic energy
- B. Thermal energy
- C. Potential energy
- D. Electrical energy
Correct answer: c
Rationale: Potential energy is the energy possessed by an object due to its position or state.
4. Kidney stones are formed when:
- A. Excess water is not reabsorbed
- B. Minerals crystallize in the urine
- C. Electrolytes become too concentrated
- D. All of the above
Correct answer: B
Rationale: The correct answer is B: "Minerals crystallize in the urine." Kidney stones are formed when minerals in the urine combine and crystallize, forming solid masses. This process can occur due to various factors, such as high levels of calcium, oxalate, or uric acid in the urine. Options A and C are not directly related to the formation of kidney stones. Option D is incorrect because not all the statements are true; only minerals crystallizing in the urine lead to kidney stone formation.
5. A satellite orbits the Earth at constant speed. Which force is responsible for its circular motion?
- A. Gravitational force from the Earth
- B. Thrust from the satellite's engine
- C. Friction between the satellite and the atmosphere
- D. Normal force from the Earth's surface
Correct answer: A
Rationale: This force acts towards the Earth's center, providing the centripetal force required for the satellite to move in a circle.
6. What is the largest lymphatic vessel in the body?
- A. Jugular vein
- B. Thoracic duct
- C. Subclavian vein
- D. Aorta
Correct answer: B
Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body, responsible for draining lymph from the lower half of the body, the left side of the head and neck, and the left arm. The jugular vein (A) and subclavian vein (C) are both blood vessels, not lymphatic vessels. The aorta (D) is the largest artery in the body, responsible for carrying oxygenated blood away from the heart. Understanding the anatomy of the lymphatic system is crucial for understanding the circulation and immune functions of the body.
