Answer:
(C) Redder.
Explanation:
Distant stars appear red because of the phenomenon known as “red-shift” which happens more when the star is very far from the observer .This happens because of the scattering of shorter wavelengths also by space dust. So it could be either natural redness OR distance.So we conclude that the answer is Redder.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is Chart.
You can insert an image like as given in the question using the Chart feature in the word processing document. This image called the bar graph chart.
You can insert a chart in your word processing document going through the Insert tab, then find the chart option under the Illustrations group of the command.
As you click on the chart, different types of charts will be shown to you. You can click on the required chart and insert it into the document. The inserted chart can be customized while double-clicking on the inserted chart.

Explanation:
Big data refers to huge collections of data that are difficult to process, analyze, and manage using conventional data tools. It is a core component of the 3rd platform, which also includes cloud computing, mobile devices, and social networking. The five Vs of big data are high volume, high velocity, diversified variety, unknown veracity, and low-density value. Although SQL and relational databases can be used for big datasets, a collection of alternative tools referred to as NoSQL has become popular. These tools work well when databases scale out (horizontally) and when databases are broken into subsets called shards. Modern database tools also handle dynamic scaling as devices are added when additional capacity is required. NoSQL tools are sometimes said to create schema-less databases, but they usually have some type of structure, though it may be more flexible than the relational model. A key-value data model provides each data element with a key. A column-oriented data model makes it easy to access data stored in similar fields, rather than in individual records. Two very popular NoSQL tools include Hadoop, which is a big data file system, and MapReduce which sends processing logic to the data, rather than bringing the data to the computer that performs the processing.
Answer:
def countdown(n):
if n <= 0:
print('Blastoff!')
else:
print(n)
countdown(n-1)
def countup(n):
if n >= 0:
print('Blastoff!')
else:
print(n)
countup(n+1)
number = int(input("Enter a number: "))
if number >= 0:
countdown(number)
elif number < 0:
countup(number)
<u>Outputs:</u>
Enter a number: 3
3
2
1
Blastoff!
Enter a number: -3
-3
-2
-1
Blastoff!
Enter a number: 0
Blastoff!
For the input of zero, the countdown function is called.
Explanation:
Copy the countdown function
Create a function called countup that takes one parameter, n. The function counts up from n to 0. It will print the numbers from n to -1 and when it reaches 0, it will print "Blastoff!".
Ask the user to enter a number
Check if the number is greater than or equal to 0. If it is, call the countdown function. Otherwise, call the countup function.
Answer: Point-to-point topology
Explanation:Point-to-point topology is the connection between the nodes in a simple/regular manner by establishing only one path for the communication with each other.The flow that occurs in this type of topology are of two types - bidirectional(two-way) and unidirectional(one-way) .
Thus the topology for the communication of the routers through a single communication path is done with the help of point-to-point pattern , considering each router as a point/node.
