Answer:

22.5 s is the correct answer to the given question .

Explanation:

Given that

d=7.5km=7.5\times 10^3 m

For light:

We know that speed of light c

c=3\times 10^8 m/s

We know that

Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms

For thunder :

Speed of sound ,v=332 m/s

Time\  taken\  by\  sound \\t\’=\dfrac{7500}{332}=22.59 s

Therefore the difference between time is given as follows

\Delta t= t' - \ t=22.59-2.5\times 10^{-5}=22.59 s

22.5 is the answer

Write a program that asks the user to input an integer named numDoubles. Create a dynamic array that can store numDoubles double
Hitman42 [59]

Answer:

Answered in C++

#include <iostream>

using namespace std;

int main() {

   int size;

   cout<<"Length of array: ";

   cin >> size;

   double *numDoubles = new double[size];

   double sum =0;

   cout<<"Array Elements: ";

   for(int i=0;i<size;i++){

       cin>>numDoubles[i];

       sum += numDoubles[i];

   }

   delete [] numDoubles;

   cout<<"Average: "<<sum/size;

   return 0;  

}

Explanation:

This line declares the size (or length) of the array

<em>    int size; </em>

This line prompts the user for the array length

<em>    cout<<"Length of array: "; </em>

This gets the input from the user

<em>    cin >> size; </em>

This dynamically declares the array as of double datatype

<em>    double *numDoubles = new double[size]; </em>

This declares and initializes sum to 0

<em>    double sum =0; </em>

This prompts the user for elements of the array

<em>    cout<<"Array Elements: "; </em>

The following iteration gets input from the user and also calculates the sum of the array elements

<em>    for(int i=0;i<size;i++){ </em>

<em>        cin>>numDoubles[i]; </em>

<em>        sum += numDoubles[i]; </em>

<em>    } </em>

This deletes the array

<em>    delete [] myarray; </em>

This calculates and prints the average of the array

<em>    cout<<"Average: "<<sum/size; </em>
