Example or Analogy
Think of this sample paper as your exam rehearsal. Just as athletes train before the big race, solving these sample papers builds speed, accuracy, and conceptual strength. Each question you practice now reduces stress during your final board exam.
Sample Example Question
Q: Why is sound considered a form of energy? Give one example to support your answer.
Answer: Sound is produced by vibration, and these vibrations transfer energy through the medium. For example, when a tuning fork vibrates, it sets the air molecules into motion, transferring energy that our ears perceive as sound.
Important Facts / Formulas (For Quick Revision)
- Density = Mass / Volume
- Force = Mass × Acceleration (F = ma)
- Work = Force × Displacement
- Speed = Distance / Time, Acceleration = (v − u)/t
- Photosynthesis Equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
- Ohm’s Law: V = IR
- Power: P = Work / Time = VI
Quick Quiz (2 Questions)
- State Newton’s third law of motion and give one everyday example.
- Define photosynthesis and write its balanced chemical equation.
Answer Key
- Newton’s Third Law: For every action, there is an equal and opposite reaction. Example – A rocket propels forward as exhaust gases push backward.
- Photosynthesis: The process by which green plants prepare food using sunlight, CO₂, and water. Equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
