Answer:
They take a step-by-step approach to performing a task. 
They break the task into manageable steps. 
They identify the tasks that will repeat.
They can be written in a computer language to create a program for a computer to follow.
Explanation:
An algorithm is made up of a series of instructions that have a start point that eventually culminates in an endpoint. It is used in calculations and data processing. Some of the characteristics of algorithms include;
1. They take a step-by-step approach to performing a task. There are well-defined tasks that pass through a series of successive steps before the final culmination.
2. They break the task into manageable steps. There are definite manageable steps that tasks must be broken into to ensure successful execution.
3. They identify the tasks that will repeat and execute them when the program is reading. 
4. They can be written in a computer language to create a program for a computer to follow.
 
        
             
        
        
        
Answer:
Following are the program to this question:
#include <iostream> //defining header file
using namespace std;
int hailstoneLength(int n) //defining method hailstoneLength
{
int t=1; //defining integer variable assign  
while(n!=1) //define a loop that checks value is not equal to 1
{
if(n%2==0) // check even number condition
{
n=n/2; // divide the value by 2 and store its remainder value in n
t++; //increment value of t by 1.
}
else
{
n=n*3+1; //calculate and hold value in n  
t++; //increment value of t variable by 1  
}
}
return t; //return value
}
int main() //defining main method
{
int n; //defining integer variable
cout<<"Enter any number: "; //print message
cin>> n; //input value
cout<<hailstoneLength(n); //call method and print its value
return 0;
}
Output:
Enter any number: 3
8
Explanation:
Program description can be given as follows:
- In the given C++ language program an integer method "hailstoneLength", is declared, that accepts an integer variable "n" in its parameter.
- Inside the method, an integer variable t is declared, that assign a value that is 1, in the next line, a while loop is declared, that uses if block to check even condition if number is even it divide by 2 and increment t variable value by 1.
- If the number is odd it will multiply the value by 3 and add 1 and increment t by 1 then it will go to if block to check value again. when value of n is not equal to 1 it will return t variable value.
- In the main method, an integer variable "n" is used that call the method and print its return value.
 
        
             
        
        
        
Answer: allowing time to do an after-school activity once studying is done
Explanation: Motivation could be explained as any event, factors or circumstances which increases an individual's willingness, zeal or strength to do something. Motivation could also be inform of incentive or reward which one stands to gain when a certain assignment or mission is accomplished. 
However, Intrinsic motivation refers to a class of motivation which are triggered naturally. When a motivation is intrinsic, there is no usually no obvious and or external source of motivation, incentive or reward attached to one's quest of doing something. In the scenario above, all other options except allowing time to do an after-school activity once studying is done have a lucid external incentive which the individual stands or aims to achieve by studying.
