The correct Answer is:
To solve the question "A big explosion on the moon cannot be heard on the earth because," we need to analyze the nature of sound and the conditions in space. ### Step-by-Step Solution: 1. **Understanding Sound Waves**: Sound is a mechanical wave that requires a medium (like air, water, or solids) to travel. It cannot propagate through a vacuum. 2. **Condition of Space**: The space between the Earth and the Moon is a vacuum. There is no air or any other medium present in space. 3. **Implication of a Vacuum**: Since there is no medium in space, sound waves produced by an explosion on the Moon cannot travel through the vacuum to reach the Earth. 4. **Conclusion**: Therefore, the reason a big explosion on the Moon cannot be heard on Earth is that sound waves require a material medium for propagation, and there is no such medium in the vacuum of space. ### Final Answer: A big explosion on the moon cannot be heard on the earth because sound waves require a material medium for propagation, and there is no medium in space.
