Answer:

A critical path refers to a sequence of task activities whose order and durations directly affect the completion date of a project.

Explanation:

A critical path refers to a sequence of task activities whose order and durations directly affect the completion date of a project. The sequence of task and activities can be either parallel or serial which leads to completion of project at the earliest. Option (a) is false as the critical path directly affects the completion date but not indirectly. Option (c) is false as the tasks can be either serial but not parallel always. Option (d) is false as critical path directly effects the completion date which means 100% of the completion of the project not the 40% of the completion of the project. Option (e) none of these is false as the answer is option (b).

Before going into space, astronauts spend many hours training on flight simulators allowing them to learn how to fly without lif

MaRussiya [10]

Answer:

The short answer is, for full-mission flight simulators, specifically by NASA, are built with actual hardware and supported by simulation software. These software take into account every possible scenarios that could be adjusted based on the training. As for the hardware, they receive signals from the software on what they should do.

Explanation:

Some technologies involved are (which are also part of the FAA's requirements):

6 Degrees of Freedom for motion
Visual systems
Realistic acoustics
Visual effects

This also involves a lot of robotics.

On the topic of motion:

One big and important feature is how motion is simulated - which takes a combined effort of both software and hardware to actually simulate how external forces can also affect the body.

It also takes into account the vibration that is experienced during launch.

The 6 degrees of freedom for motion includes:

Up and down
Left and right - sliding motion
Back and forward
Yaw - turning motion
Pitch - look up and down
Roll

For flight simulators, there are several levels and requirements being used in the aviation training industry. But one thing that you need to know is that the hardware and software mostly take into account motion.

On the topic of visual systems:

The pilots or crew should have a visual representation of what the outside world looks like with at least 150 degrees of view.

Realistic acoustics:

During simulations, actual sounds should also be present based on the real-life sounds produced during flight.

Visual effects:

If the pilot pivots to the right, or is about to breach the exosphere, the system's display should also take that into account and show it to the crew. This also includes visual effects for specific motions being done.

And as a bonus:

Just until recently, everything was analog (meaning, with dials, buttons, and levers) for the actual aircraft simulation that the pilots/astronauts are using. Update are now being made in NASA and SpaceX along with other rocket and spacecraft companies to move from analog to digital (with touch screens).

While this is an abridged version, it should help you to understand the complexities of a flight simulator.

mestny [16]

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
