2. What are the characteristics of a wave?

3. How can black holes be detected?

4. What are the components of an atomic nucleus?

5. According to Einstein's theory of general relativity, if two objects have a gravitational pull on one another, and one changes its mass or distance from the other, how quickly does the effect of this change travel to the other object?
