physics

1. In which direction do the particles of the medium move in a transverse wave?

A. Perpendicular to the direction of wave travel
B. Parallel to the direction of wave travel
C. In a circular motion
D. Opposite to the direction of wave travel

Correct answer: a

Rationale: In a transverse wave, particle displacement occurs perpendicular to the direction of wave travel.

2. A rectangular bandage measures 5cm by 8cm. What is the area covered by the bandage?

A. 10cm
B. 13cm
C. 40cm^2
D. 64cm^2

Correct answer: C

Rationale: 40cm^2: Multiply the length (5cm) by the width (8cm).

3. He discusses the goal of the department. Which of the following statements is a goal?

A. Increase the patient satisfaction rate
B. Eliminate the incidence of delayed administration of medications
C. Establish rapport with patients.
D. Reduce response time to two minutes.

Correct answer: A

Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.

4. What is the main target organ for insulin, the hormone produced by the pancreas?

A. Liver
B. Kidneys
C. Muscles
D. Brain

Correct answer: C

Rationale: The correct answer is C: Muscles. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. Its main target organs are the liver, muscles, and adipose tissue. Insulin acts on muscle cells to promote glucose uptake and storage as glycogen, helping to lower blood sugar levels. While the liver and adipose tissue are also important targets for insulin, muscles are particularly significant for glucose utilization and storage. Therefore, muscles are considered the main target organ for insulin in the body.

5. What is the unit of measurement for momentum?

A. Newton-second (N·s)
B. Kilogram-meter (kg·m)
C. Joule (J)
D. Meter per second (m/s)

Correct answer: A

Rationale: Momentum is defined as the product of an object's mass and its velocity. The unit of mass is kilograms (kg) and the unit of velocity is meters per second (m/s). Therefore, the unit of momentum is kilogram-meter per second (kg·m/s). By Newton's second law of motion (F = ma), force is measured in Newtons (N), which is equivalent to kg·m/s². Therefore, multiplying the unit of force (N) by the unit of time (s) gives the unit of momentum as Newton-second (N·s).
