Answer:
- Transform binary or unary M:N relationship or associative entity with its own key.
Explanation:
Transform binary relation is described as the method through which a decimal can easily be converted into binary while the unary relationship is described as a relationship in which both the two participants occurs from the same entity.
In the given case, 'transform binary or unary M:N relationship' can be created using 'the primary key linked with the relationship plus any non-key aspects of the relationship and the primary keys of the related entities' as it displays the existence of a relationship between the occurrences of a similar set of the entity i.e. associative entity here.
 
        
             
        
        
        
Answer:
a. quantum computing and telecommunications 
Explanation:
Both quantum computing and telecommunications need materials with specific optical, electrical, and magnetic properties to advance, and nanotechnologies open the opportunity for nanomaterial with incredible properties. From antennas with special magnetic properties to faster optical fiber from more stable material to store qubits to super thermal insulators, nanotechnologies will change the way we build and design telecommunication systems, and it will allow us to build stable and reliable quantum computers.

Answer:- Major property of a good hash code is that objects which are equal should return the same hash code .
Explanation: Hash codes is a numeric value which  is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable. 
If two objects are equal then by the method of equal(object) if the hashcode() function is called on both the objects , they produce the same value.
