Explanation:
Alberta Einstein teaches a business class at Podunk University. To evaluate the students in this class, she has given three test
s. It is now the end of the semester and Alberta asks you to create a program that inputs each student’s test scores and outputs the average score for each student and the overall class average. (Hint: The outer loop should allow for Ms. Einstein to input all the students, one by one, and the inner loop should accept the three exam scores and compute the average for each student.)

Entropy is an extensive property of the system entropy change that value of entropy change can be determined for any process between the states whether reversible or not. i have attached the formula to calculate entropy change which is independent of whether the system is reversible or not and can be determined for any process.
Answer:
the percent increase in the velocity of air is 25.65%
Explanation:
Hello!
The first thing we must consider to solve this problem is the continuity equation that states that the amount of mass flow that enters a system is the same as what should come out.
m1=m2
Now remember that mass flow is given by the product of density, cross-sectional area and velocity
(α1)(V1)(A1)=(α2)(V2)(A2)
where
α=density
V=velocity
A=area
Now we can assume that the input and output areas are equal
(α1)(V1)=(α2)(V2)
Now we can use the equation that defines the percentage of increase, in this case for speed
Now we use the equation obtained in the previous step, and replace values
the percent increase in the velocity of air is 25.65%
