Answer: knowing what you spend".
Explanation:
The reason to use cash for making purchases is to know how much one has spent.
When we use cash rather than using credit card, it's easier for one to know how much that has been spent. Also, one can easily know when he or she need to stop spending. Therefore, the correct answer is "knowing what you spend".
Answer:
The code to this question can be given as:
Code:
public interface Test //define interface
{
public abstract Duration getDuration(); //define method
getDuration.
public abstract Result check(int a);
//define method
check .
public abstract double getScore();
//define method getScore.
}
Explanation:
In the above code, we define an interface that is "Test" inside an interface, we define three methods that can be defined as:
- First, we define a method that is "getDuration" that method returns Duration as an object.
- Second, we define a method that is "check" this method accepts an integer parameter that is a and return Result.
- The third method is "getScore" this method will return a double value.
Answer:
The correct answer to the following question will be "Adaptive Optics".
Explanation:
- AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
- It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.
- It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.
- Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.
Therefore, Adaptive Optics is the right answer.
