What is simulation software?

The process of simulating a genuine phenomenon with a set of mathematical formulas is the foundation of simulation software. It is essentially a program that allows the user to simulate an operation and view it without really conducting it.

Simulation is a decision-making and decision-support tool. You can use simulation software to assess, compare, and optimize different designs, programs, and policies. As such, it can be used to explain and defend decisions to multiple stakeholders.

By allowing the corporation to evaluate concepts early in the process before prototype automobiles are constructed, simulation software can save the company money.

Therefore, the correct option is D, I, II, and III.

All of the following items may be sent via email EXCEPT *

Answers

Answer:

hard copy attachments

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.

One of the most widely used communication channel or medium around the world is an e-mail (electronic mail).

An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send and receive texts and multimedia messages over the internet.

The following documents or files such as soft copy attachments, web links and web pages may be sent from one user to another through the use of an email.

However, hard copy attachments cannot be sent via email because they're physical documents and as such requires that they be delivered physically to the recipient.

In conclusion, you can only send soft copy documents that you cannot feel or touch with your hands over the internet and via email. Thus, an email is only designed to accept soft copy documents or files (attachments) but certainly not hard copy documents (attachments) in our technological era.

rem wap a programe using function procedure to calculate simple interest

Answers

Answer:

The program in Python is as follows:

def interest(P,R,T):

    [tex]I = P * R * T/100[/tex]

   return I

   

P = float(input("Principal: "))

R = float(input("Rate (%): "))

T = float(input("Time (years): "))

print(interest(P,R,T))

Explanation:

Required

Simple interest program using function

This defines the function

def interest(P,R,T):

This calculates the simple interest

   [tex]I = P * R * T/100[/tex]

This returns the calculated interest

   return I

The main begins here

These get inputs for principal, rate and time

P = float(input("Principal: "))

R = float(input("Rate (%): "))

T = float(input("Time (years): "))

This calls the interest function

print(interest(P,R,T))
