Answer:
19.95
Explanation:
Power ratio (in db) = 10 * log [P(out)/P(in)]
Here, P(in) and P(out) correspond to input and output power in Watts respectively.
This implies, 13 db = 10 * log [P(out)/P(in)]
Rearranging, log [P(out)/P(in)] = (13/10)
Or, P(out)/P(in) = 10 ^ 1.3 = 19.95
But, P(out)/P(in) corresponds to the power ratio of output and input power.
So the required power ratio corresponds to 19.95

Answer:
#include <iostream>
using namespace std;
int main()
{
int day;
cout<<"Enter a number for the day of the week"<<endl;
cin>> day;
switch (day) {
case 1: cout << "Monday"<< endl; break;
case 2: cout << "Tuesday" << endl; break;
case 3: cout << "Wednesday" << endl; break;
case 4: cout << "Thursday" << endl; break;
case 5: cout << "Friday" << endl; break;
case 6: cout << "Saturday" << endl; break;
case 7: cout << "Sunday" << endl; break;
default: cout<<"Error, You entered an invalid day"<<endl;
}
return 0;
}
Explanation:
The program is written using a switch statement in C++ programming language. we start off by creating a variable day of type integer, which is received using the cin statement. We then use switch statement to test the value using the conditions stated in the question. We use the default statement which acts like an else statement to handle the an invalid situation
Answer:
Byzantium was located on trade routes and could be better protected.
Explanation:
Byzantium became the capital of the Roman Empire in 330, with the established objective of fulfilling a fundamental role in the control of the commercial routes used by Rome to the East: this city was located in the passage of these commercial routes, thus which was fundamental its protection in order to control trade in the area.
