Answer:
Hello attached is the Java program written to solve the problem
The Pet.java and Dog.java files are unaltered
Explanation:
The input and output codes are attached as well i.e the second image is the input while the third image is the output code
Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.
It is both true that <span>Technician A says that the excessive length of a heater hose is intended to protect the heater core from undue stress. Technician B says that excessive wear adds to the length of a heater hose, and a replacement heater hose should be roughly three to four inches shorter than its predecessor. So the asnwer is letter B.</span>

Answer:
// here is code in C++(bmi.cpp).
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
float weight,height;
cout<<"enter the weight(in kilograms):";
//read the weight
cin>>weight;
cout<<"enter the height(in meters):";
//read the height
cin>>height;
// calculate the bmi
float bmi=weight/(pow(height,2));
// print the body-mass index with two decimal places
cout<<"BMI is: "<<fixed<<setprecision(2)<<bmi<<endl;
return 0;
}
Explanation:
Read the weight from user and assign it to variable "weight",read height and assign it to variable "height".Then find the body-mass index as (weight/height^2).Here weight should be in kilograms and height should be in meters.
Output:
enter the weight(in kilograms):75
enter the height(in meters):1.8
BMI is: 23.15
