Physics

1. What is the difference between a real image and a virtual image formed by a lens?

Correct answer: A

Rationale: Real images are formed by the actual convergence of light rays and can be projected onto a screen, while virtual images are formed by the apparent divergence of light rays and cannot be projected.

2. What is the process by which a large, unstable nucleus splits into two smaller nuclei, releasing neutrons and energy?

Correct answer: D

Rationale: Nuclear fission involves splitting a heavy nucleus into smaller fragments, releasing neutrons and energy.

3. Define "friction" in terms of opposing motion.

Correct answer: c

Rationale: Friction acts opposite to the direction of motion, resisting or slowing down the movement of objects.

4. A spring with a spring constant of 100 N/m is stretched 0.2 m from its equilibrium position. What is the potential energy stored in the spring?

Correct answer: B

Rationale: Potential energy in a spring is calculated as 1/2 * k * x², where k is the spring constant and x is the displacement from equilibrium. Therefore, the potential energy is 1/2 * 100 N/m * (0.2 m)² = 4 J.

5. The author most likely included information about the Silk Road to...

Correct answer: C

Rationale: The Silk Road directly impacts Petra's history and prosperity, making it relevant to the historical context

6. A patient weighs 180 pounds. What is their weight in kilograms (1kg = 2.2lbs)?

Correct answer: C
