Write a program that allows the user to enter a time in seconds and then outputs how far an object would drop if it is in free f

all for that length of time. Assume that the object starts at rest, there is no friction or resistance from air, and there is a constant acceleration of 32 feet per second due to gravity. Use the equation: distance = acceleration x time-squared divided by 2

Answer:

// here is code inn c++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variable

   int t;

   double acc=32;

   cout<<"Enter the time in seconds:";

   // read the time in seconds

   cin>>t;

   // Calculate the distance=acceleration x time-squared divided by 2

   double dis=acc*(t*t)/2;

   // print the distance

   cout<<"distance is: "<<dis<<" feet."<<endl;

return 0;

}

Explanation:

Read the time in seconds from user and assign it to variable "t". declare and initialize variable "acc" with 32.Find the distance as "dis=acc*(t*t)/2". Print the distance.

Output:

Enter the time in seconds:10

distance is: 1600 feet.

What is workflow? how do you create your own workflow?
lana66690 [7]
A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information.


Create a detailed outline of what you want to achieve and sketch a workflow diagram before using workflow chart software or templates. This will help to ensure your chart is accurate and complete. Always consider your process and workflow manageability when inserting logic in your workflow chart. You can use decision symbols, connectors and text boxes. Always confirm the accuracy of your workflow chart with other stakeholders.


(If you need to know what the workflow diagrams layout is just look it up. GL.)

Consider an error-free 64 kbps satellite channel used to send 512 byte data frames in one direction, with very short acknowledge
Vladimir [108]

Answer:

The answer is "2".

Explanation:

In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:

Given values:

Bandwidth = 64 kbps

Data frames = 512 bytes  

Propagation Time (t​​​​​​p ) =270 ms

Change Bandwidth  kbps to bps:

1 kb= 1024 bytes

calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps

1 bytes = 8 bits

512 bytes = 512 × 8 =  4096 bits

Frame length = 4096 bits

Formula

Transmission time (T​​​​​​t) = Frame length /Bandwidth

Window size = 1+2a

where a = Propagation time/Transmission time

Calculate Transmission time:

Transmission time (T​​​​​​t) = 4096 / 65536

Transmission time (T​​​​​​t)= 625 m.sec

Calculate Window size:

Window size = 1+2(270/625)

Window size = 1+2(0.432)

Window size = 1+0.864

Window size = 1.864

Window size = 2

Overloading in methods are popular in programming, and why overloading is important.
Cerrena [4.2K]

Answer:

 Yes, overloading is one of the methods which are popular in programming language. Overloading basically refers to the same function but different signature called function overloading or method overloading. It is the ability to define the multiples method by using the single identifier.

The overloading is important because it has the ability to design the multiple method by using similar name. It also provide the high flexibility to the programmers to call the same method in the data. overloading basically provide the high clarity in the code.

Overloading is used to achieved the compile time polymorphism.  

Following are program of function overloading in c++ are:

Class abc // creating class

{

public:

int p;

void fun() // function fun with no parameter/

{

cout<<” hello “;

}

void fun(int a) // function fun with parameter

{

p=a;

cout<<p;

}

};

int main() // main function

{

abc ob; // creating object

ob.fun();// print hello;

ob.fun(6);// print 6

return 0;

}

Explanation:

In this program the function fun() have same name but different signature in the main method we create the object of class abc i.e ob. ob.fun() this statement called the function with no parameter and ob.fun(6) this statement will called the function with integer parameter.
