Answer:

The cpp program for the given scenario is shown below.

#include <stdio.h>

#include <iostream>

using namespace std;

int main()

{

   //variables to hold both the given values

   double normal_rate = 0.60;

   double rate_1000 = 0.45;

   //variable to to hold user input

   double kwh;

   //variable to hold computed value

   double bill;

   std::cout << "Enter the number of kilowatt hours used: ";

   cin>>kwh;

   std::cout<<std::endl<<"===== ELECTRIC BILL ====="<< std::endl;

   //bill computed and displayed to the user

   if(kwh<1000)

   {

       bill = kwh*normal_rate;

       std::cout<< "Total kilowatt hours used: "<<kwh<< std::endl;

       std::cout<< "Rate for the given usage: $"<<normal_rate<< std::endl;

       std::cout<< "Total bill: $" <<bill<< std::endl;

   }

   else  

   {

       bill = kwh*rate_1000;

       std::cout<< "Total kilowatt hours used: "<<kwh<< std::endl;

       std::cout<< "Rate for the given usage: $"<<rate_1000<< std::endl;

       std::cout<< "Total bill: $" <<bill<< std::endl;

   }

   std::cout<<std::endl<< "===== BILL FOR GIVEN VALUES ====="<< std::endl;

   //computing bill for given values of kilowatt hours

   double bill_900 = 900*normal_rate;

   std::cout << "Total bill for 900 kilowatt hours: $"<< bill_900<< std::endl;

   double bill_1754 = 1754*rate_1000;

   std::cout << "Total bill for 1754 kilowatt hours: $"<< bill_1754<< std::endl;

   double bill_10000 = 10000*rate_1000;

   std::cout << "Total bill for 10000 kilowatt hours: $"<< bill_10000<< std::endl;

   return 0;

}

OUTPUT

Enter the number of kilowatt hours used: 555

===== ELECTRIC BILL =====

Total kilowatt hours used: 555

Rate for the given usage: $0.6

Total bill: $333

===== BILL FOR GIVEN VALUES =====

Total bill for 900 kilowatt hours: $540

Total bill for 1754 kilowatt hours: $789.3

Total bill for 10000 kilowatt hours: $4500

Explanation:

1. The program takes input from the user for kilowatt hours used.

2. The bill is computed based on the user input.

3. The bill is displayed with three components, kilowatt hours used, rate and the total bill.

4. The bill for the three given values of kilowatt hours is computed and displayed.

If a storm is 7.5 kilometers away, how much time is expected between observations of lightning and thunder? Round your answer to
Svetlanka [38]

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
