Answer:
Explanation:
The following Python code creates all of the necessary functions in order to request and validate all of the inputs from the user. Once everything is entered and validated it calculates the total fee and outputs it to the user. Also calls the entire class at the end using a test variable...
class Customer:
library_card = 0
patrons_name = ""
patrons_address = ""
type_of_book = ""
book_title = ""
days_overdue = 0
fee = 0.0
book_list = ['paperback regular', 'paperback best seller', 'magazine', 'hardcover']
def __init__(self):
self.library_card = self.get_library_card()
self.patrons_address = input("Patron's Address: ")
self.book_title = input("Book Title: ")
self.type_of_book = self.get_type_of_book()
self.days_overdue = float(self.get_days_overdue())
self.calculate_total()
print("Your total Fee is: " + str(self.fee))
def get_library_card(self):
library_card = int(input("Enter 4-digit library card number: "))
if (type(library_card) == type(0)) and (len(str(library_card)) == 4):
return library_card
else:
print("Invalid Card number:")
self.get_library_card()
def get_type_of_book(self):
type_of_book = input("Type of Book 1-4: ")
if (int(type_of_book) > 0) and (int(type_of_book) <= 4):
return int(type_of_book)
else:
print("Invalid Type")
self.get_type_of_book()
def get_days_overdue(self):
days_overdue = input("Number of Days Overdue: ")
if int(days_overdue) >= 0:
return days_overdue
else:
print("Invalid number of days")
self.get_days_overdue()
def calculate_total(self):
if self.type_of_book == 1:
self.fee = 0.20 * self.days_overdue
if self.fee > 8:
self.fee = 8
elif self.type_of_book == 2:
self.fee = 0.50 * self.days_overdue
if self.fee > 15:
self.fee = 15
elif self.type_of_book == 3:
self.fee = 0.25 * self.days_overdue
if self.fee > 5:
self.fee = 5
else:
self.fee = 0.30 * self.days_overdue
if self.fee > 23:
self.fee = 23
test = Customer()
Answer:
1. Hydrostatic pressure.
2. Pressure.
3. Equilibrium forces.
Explanation:
1. <u>Hydrostatic pressure</u>: pressure exerted by a stationary liquid. It is simply the pressure in a liquid such as water at a specific depth.
Mathematically, hydrostatic pressure is given by the formula;
Where:
- H.P is the hydrostatic pressure of a liquid.
- rho represents the density of a liquid.
- g is the acceleration due to gravity.
- d is the depth (height) of a liquid.
2. <u>Pressure</u>: it is the force in a direction perpendicular to a given surface area. Thus, it's typically measured in Newton per meters (N/m²).
Mathematically, pressure is given by the formula;
3. <u>Equilibrium forces</u>: a pair of forces whose resultant is zero. It is also referred to as balanced forces because the resultant of all the pair of forces acting on a body or system is at equilibrium (balanced).
