Answer and Explanation:
Omnidirectional antenna are those antennas which receives the signals from multiple directions equally.These are the antennas that cannot get the signal from a particular direction thus gives the low throughput.
To get high throughput, directional antennas should be installed because they receive the signal from a particular direction only .Thus the signal received from these antenna work for a certain area.Example-Television antenna at homes are directional antennas names as Yagi-uda antennas.

Explanation:
The attributes that are examined for the query are the attributes of the table that are mentioned in the select statement and where clause.
So according to first query we are working on all attribues of Emp table so all of the attributes of Emp table are examined.In second query we selecting all attributes of both the tables hence all attributes of both the table and same in the next query.
In fourth query though the query is not complete where clause is missing but we have eid from Emp and dname from Dept tables for sure and the attributes mentioned in where clause will also be present.
Answer:
//Define class
public class Main {
//define main method
public static void main(String[] args)
{
//declare and initialize the double type variable to 128
double mexico = 128;
//declare and initialize the double type variable to 323
double us = 323;
//declare and initialize the integer type variable to 0
int yr = 0;
//set the while loop to check which is greater
while (mexico < us)
{
//increment in the variable by 1
yr++;
//initialize in the variables acc. to the percentage
mexico *= 1.0101;
us *= 0.9985;
}
//print the following results
System.out.println("Population of the Mexico will be exceed the population U.S. in " + yr + " years");
System.out.println("Population of the Mexico will be " + mexico + " million");
System.out.println("and population of the U.S. will be " + us + " million");
}
}
<u>Output</u>:
Population of the Mexico will be exceed the population U.S. in81 years
Population of the Mexico will be 288.88435953355025 million
and population of the U.S. will be 286.0198193927948 million
Explanation:
<u>Following are the description of the program</u>.
- Firstly, we define the class 'Main' and inside it, we define the main method.
- Then, declare two double data type variables which are 'mexico' and 'us' and initialize in it to 128 and 323.
- Declare integer data type variable 'yr' and initialize in it to 0.
- Set the while loop and pass the condition to check that the variable 'mexico' is less than the variable 'us' then, increment in the variable 'yr' by 1 and multiply the variables 'us' and 'mexico' by the following percentage.
- Finally, print the following results with the message.
