Compute the acceleration of gravity for a given distance from the earth's center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth's center (stored in variable distCenter).
#include
using namespace std;
int main() {
double G = 6.673e-11;
double M = 5.98e24;
double accelGravity;
double distCenter;
cin >> distCenter;
/* Your solution goes here */
cout << accelGravity << endl;
return 0;
}

Answers

Answer:

Replace /* Your solution goes here */ with the following expression

accelGravity = (G * M) / (distCenter *distCenter );

Explanation:

Required

Complete the code

The equivalent expression of (G * M) / (d^2) is:

(G * M) / (distCenter *distCenter );

The expression must be stored in accelGravity.

So, we have:

accelGravity = (G * M) / (distCenter *distCenter );

Write a program that repeatedly accepts as input a string of ACGT triples and produces a list of the triples and the corresponding amino acids, one set per line. The program will continue to accept input until the user just presses ENTER without entering any DNA codes.

Answers

Answer:

Explanation:

The following code is written in Python. I created a dictionary with all the possible gene combinations and their corresponding amino acids. The user then enters a string. The string is split into triples and checked against the dictionary. If a value exists the gene and amino acid is printed, otherwise an "Invalid Sequence" error is printed for that triple. The program has been tested and the output can be seen in the attached image below.

Write a program that randomly chooses among three different colors for displaying text on the screen. Use a loop to display 20 lines of text, each with a randomly chosen color. The probabilities for each color are to be as follows: white 30%, blue 10%, green 60%. Suggestion: Generate a random integer between 0 and 9. If the resulting integer falls in the range 0 to 2 (inclusive), choose white. If the integer equals to 3, choose blue. If the integer falls in the range 4 to 9 (inclusive), choose green.

Your location has been assigned the 172.149.254.0 /24 network. You are tasked with dividing the network into 13 subnets with the maximum number of hosts possible on each subnet.

Required:
a. What is the dotted decimal value for the subnet mask?
b. How many additional bits will you need to mask in the subnet mask?

Answers

The subnet mask would be a 32-bit integer which is formed by assigning the host bits to all 0's and the networking bits to so many 1's.In this method, the subnetting separates the IP address between host and network addresses.The subnet mask covers an IP address with its 32-bit number, thus the term "mask".

Given:

Network IP address [tex]\bold{= 172.149.254.0 /24}[/tex]

Subnet numbers [tex]\bold{= 13}[/tex]

Calculating the borrow bits:

[tex]\to \bold{= ceil(\log_{2} 13) = 4 \ bits}[/tex]

a)

Calculating the dotted decimal value for the subnet mask:

[tex]\to \bold{11111111.11111111.11111111.00000000}\\\\\to \bold{255.255.255.240}\\\\[/tex]

b)

The additional bits which will be needed to mask the subnet mask that is = 4.

An engineer is configuring AMP for endpoints and wants to block certain files from executing. Which outbreak control method is used to accomplish this task

Answers

Question Completion with Options:

A. device flow correlation

B. simple detections

C. application blocking list

D. advanced custom detections

Answer:

The outbreak control method that is used to accomplish the task of configuring AMP for endpoints and to block certain files from executing is:

C. application blocking list

Explanation:

The application blocking list creates a list of application files, which the AMP continuously tracks and analyzes to compare the file activities with previous cyber attacks.  Specifically, the AMP for Endpoints is a cloud-managed endpoint security solution, which provides a retrospective alert to prevent cyber-security threats, and rapidly detects, contains, and remediates malicious files on the endpoints.

continuously tracks and analyzes files and file activities across your systems, and compares these events to what preceded or happened in past attacks. If a file exhibits malicious behavior, the AMP provides you with a retrospective alert which enables you to stop a potential threat from succeeding.

Good big data management is key to compete in a globalized market. With employees, suppliers and customers physically spread across different cities and countries, the better the data is handled in an organization, the greater its ability to react to market demand and its competitors.

Databases are nowadays an indispensable pillar to manage all the information handled by an organization that wants to be competitive. However, at a certain point of development in a company, when growth is sustained and the objective is expansion, the doubt faced by many managers and system administrators is whether they should continue to use a database system, or if they should consider the leap to a data warehouse. When is the right time to move from one data storage system to another?
