The program is an illustration of built-in functions
<h3>What are
built-in functions?</h3>
They are named program statements that have a predefined purpose
<h3>The actual program</h3>
The program written in C++, where comments are used where required is as follows:
#include <iostream>
#include <cmath>
#include <ios>
#include <iomanip>
using namespace std;
int main (){
double x;
double y;
double z;
cin>>x;
cin>>y;
//This calculates the given expression
z = pow(sqrt(y),x);
cout << fixed<<setprecision(2);
cout<<z<<endl;
return 0;
}

Statement A is true. R4 is not part of the circuit since it has one terminal not connected. The other resistors are in series, so the same current flows through them. Hence they will dissipate equal power.
Answer:
Physical layer
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.
This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.
