<u>Explanation:</u>
Remember, an algorithm in simple words means a set of instructions or steps to be followed in other to solve a problem.
Note, to decide which commute is cheaper, it means the output of the algorithm should be the cheaper way to commute.
Using pseudocode do the following;
- determine the inputs and outputs of the problem
- arrange the identified problem into micro-tasks
- describe each micro-tasks in the pseudocode
- Test the pseudocode by solving the problem.
Answer:
The program in Python is as follows:
num1 = int(input())
num2 = int(input())
if num1 >=0 and num2 >= 0:
print(num1+num2)
elif num1 <0 and num2 < 0:
print(num1*num2)
else:
if num1>=0:
print(num1**2)
else:
print(num2**2)
Explanation:
This gets input for both numbers
num1 = int(input())
num2 = int(input())
If both are positive, the sum is calculated and printed
<em>if num1 >=0 and num2 >= 0:</em>
<em> print(num1+num2)</em>
If both are negative, the products is calculated and printed
<em>elif num1 <0 and num2 < 0:</em>
<em> print(num1*num2)</em>
If only one of them is positive
else:
Calculate and print the square of num1 if positive
<em> if num1>=0:</em>
<em> print(num1**2)</em>
Calculate and print the square of num2 if positive
<em> else:</em>
<em> print(num2**2)</em>
Answer:
Friction (drag)
Explanation:
The force resisting motion through a fluid is a type of friction, that is called drag.
