1 answer:

8 0

Answer: in a net force acting forward on the balloon thrust.The balloon flies forward under the influence of the thrust, and the air coming out of the back of the balloon is the equal and opposite reaction to the thrust. same goes for a rocket

) how many bits are used for host number on the child network (subnet) , b) how many usable addresses can exist on this child ne

vovikov84 [41]

Answer:

Machine’s IP=126.127.85.170, Machine’s Netmask=/27, Parent’s Netmask=255.255.240.0 .

a) Machine's Netmask = /27 : therefore no. of remaining bits for hosts =32-27 = 5 bits.

b) No. of usable addresses in the child network = 25 -2 = 32-2 =30 [Since first(network ID of the machine) and last ip (broadcast address of the machine ) addresses are not used ]

c) first usable address is on this child network (subnet) =

First, find out the network id of machine can be found out by doing bitwise AND machine's IP and Machine's subnet mask :

01111110. 01111111.01010101.10101010 (IP)

11111111. 11111111 .11111111 .11100000 (Subnet Mask)

01111110. 01111111. 01010101.10100000 (Network ID )

first usable address is on this child network (subnet) : 01111110. 01111111. 01010101.10100001

: 126.127.85.161

d) what the last usable address is on this child network (subnet) : 01111110. 01111111. 01010101.10111110

: 126.127.85.190

e) what the child network’s (subnet's) broadcast address is :

In the directed broadcast address , all the host bits are 1. Therefore, broadcast address :

01111110. 01111111. 01010101.10111111 (126.127.85.191)

f) what the child network's (subnet's) network number is : Network ID has already been calcuulated in part c .

01111110. 01111111. 01010101.10100000 (126.127.85.160)

Look at the following structure declaration.

myrzilka [38]

Answer:

B. a tag

Explanation:

In the structure definition given below:

struct Employee

{

string name;

int idNum;

};

Employee corresponds to the tag of the structure. The tag is used to create additional instances of the structure. For example:

struct Employee e1;

struct Employee e2;

name and idNum are members of the Employee structure and are referenced using the dot notation. e.g.,

struct Employee e1;

e1.idNum=1;

Write a method that takes a RegularPolygon as a parameter, sets its number of sides to a random integer between 10 and 20 inclus

Sergio [31]

Answer:

import java.lang.Object

import java.lang.Math

public class RegularPolygon extends java.lang.Object{

public void randomize(RegularPolygon c){

int min = 10, max1 = 20;

double min1 = 5, max1 = 12;

double range = (max - min) + 1;

double range1 = (max1 -min1) + 1

int side = (Math.random() * range) + min;

double len = (Math.random() * range1) + min1;

c.setNumSides(side);

c.setSideLength( len);

}

public static void main(String[] args) {

RegularPolygon r = new RegularPloygon();

randomize(r);

}

Explanation:

The randomize method accepts a regular polygon class as its only parameter and assigns a random number of sides and the length of these sides with the 'Math.random' function.
