physics

1. Define the term "momentum" in physics.

Correct answer: c

Rationale: Momentum is the product of an object's mass and velocity, describing its motion and resistance to changes in motion.

2. A table shows the blood pressure readings for different age groups. How do you determine the patient with the highest systolic pressure?

Correct answer: A

Rationale: The best way is to compare the average systolic pressure values for each age group to identify the highest.

3. Which sentence uses the passive voice correctly?

Correct answer: A

Rationale: Option a clearly identifies the object (letter) acted upon and the agent (Mary) performing the action in the passive voice.

4. What is the acceleration of an object moving at a constant speed of 20 m/s if it comes to a complete stop within 5 seconds?

Correct answer: C

Rationale: The acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 0 m/s (as the object comes to a complete stop), the initial velocity is 20 m/s, and the time taken is 5 seconds. Plugging these values into the formula, we get acceleration = (0 m/s - 20 m/s) / 5 s = -20 m/s / 5 s = -4 m/s². Therefore, the acceleration is -4 m/s².

5. The primary function of the respiratory system is to:

Correct answer: B

Rationale: The correct answer is B: 'Deliver oxygen to the bloodstream and remove carbon dioxide.' The primary function of the respiratory system is to facilitate gas exchange. When we breathe in, oxygen is inhaled and transported to the bloodstream, where it is delivered to cells for energy production. Simultaneously, carbon dioxide, a waste product of cellular metabolism, is removed from the bloodstream and exhaled. This process is vital for sustaining life and maintaining proper oxygen levels in the body. The respiratory system does not primarily regulate body temperature, produce antibodies, or break down food molecules for energy, making options A, C, and D incorrect.

6. Which condition is characterized by inflammation of the inner lining of the stomach?

Correct answer: D

Rationale: The correct answer is D, gastritis. Gastritis refers to the inflammation of the inner lining of the stomach, which can be caused by various factors such as excessive alcohol consumption, prolonged use of NSAIDs, or bacterial infections like H. pylori. Gastroesophageal reflux disease (GERD) is characterized by the backflow of stomach acid into the esophagus, not inflammation of the stomach lining. Diverticulitis is inflammation of small pouches that can develop in the colon, while ulcerative colitis is inflammation in the large intestine. Therefore, gastritis best fits the description of inflammation in the inner lining of the stomach.
