BBDA Is correct!!!
1. How does nanotechnology help engineers make products for the future?
- The correct answer is b. By changing a material's atomic structure, its physical properties can also be changed.
- Nanotechnology involves manipulating matter at the atomic and molecular scale to create new materials and devices with enhanced properties.
- By altering a material's atomic structure, engineers can improve its strength, conductivity, reactivity, and other properties, allowing them to create products with improved performance and functionality.
2. How are nanoparticles being used today?
- The correct answer is d. Nanoparticles are already being used in some sunscreens.
- Nanoparticles, which are particles at the nano scale, are currently utilized in various fields due to their unique properties.
- In the case of sunscreens, nanoparticles are used to improve the product's ability to block harmful UV rays without leaving a visible residue on the skin.
3. What possible solution are engineers investigating in case Earth's resources are depleted?
- The correct answer is a. mining near-Earth asteroids.
- While the development of new materials through nanotechnology (option b) is a possible solution, mining asteroids near Earth is also being investigated as a potential source of essential resources.
- Asteroids contain valuable minerals and metals that could potentially be extracted in the future to supplement Earth's diminishing resources.
