Answer:d) Mono-alphabetic substitution rules
Explanation: Poly-alphabetic cipher is the cryptography that is done by using the many alphabets in substitutional way. They are supposed to have a good security because they use cipher text alphabets for the encryption and then decrypts it.
Substitution of the alphabets is done by the rule of the mono-alphabetic substitution rules.Other given options are incorrect because they are not used in the cryptography of the alphabetic cipher. Thus option (d) is the correct answer.
The European plug takes up 220 volts while the American one takes 110 volts.
Answer:
public class Calculator {
private int total;
private int value;
public Calculator(int startingValue){
// no need to create a new total variable here, we need to set to the our instance total variable
total = startingValue;
value = 0;
}
public int add(int value){
//same here, no need to create a new total variable. We need to add the value to the instance total variable
total = total + value;
return total;
}
/**
* Adds the instance variable value to the total
*/
public int add(){
// no need to create a new total variable. We need to add the value to the instance total variable
total += value;
return total;
}
public int multiple(int value){
// no need to create a new total variable. We need to multiply the instance total variable by value.
total *= value;
return total;
}
//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
}

Answer and Explanation:
Some of the negative aspects of robots at work place:
- Lesser flexibility
- Higher maintenance and installation cost
- Future insecurity and risk if the system malfunctions
- A decline in the opportunities for humans
- Unemployment as a result of automation and robot regulated work place.
Some of the positive aspects of robots at work place:
- Higher accuracy
- Higher speeds
- More work in less time
- Productivity and hence efficiency will increase
- Cost of some operations is reduced.
- Ease of employing in dangerous and hazardous fields by using specific robots for each task
