Answer:(1) Null pointer(2)huge pointer (3) far pointer (4)near pointer

Explanation:

(1)Null pointer: null pointer is a type of pointer that points at nothing

(2)Huge pointer: Just like a far pointer, it is use to point to the a whole resident of RAM

(4) Near pointer: It can only point to a smaller segment of RAM

(5) Generic pointer is a pointer used when you have more than one item of different type to choose

Pointer: A pointer is a variable which holds the address of other variable of the specified data type(like int,float,char). In programming we basically use pointers to store the other variable's address.

What happens if two functions are defined with the same name, even if they are in different arguments within the same .py files?

yan [13]

Answer:

Following are the code to this question:

def data(a):#defining method data that accepts parameter

print (a)#print parameter value

def data(b):#defining method data that accepts parameter

print (b)#print parameter value

x=input("enter value: ")#defining variable x that5 input value from user

print(data(x))#call method data

Output:

enter value: hello..

hello..

None

Explanation:

As the above code, it is clear defines that python doesn't support the method overloading because More than one method can't be specified in a python class with the same name and python method arguments have no type.
The single argument method may be named using an integer, a series, or a double value, that's why we can say that it is not allowed.

If a star system 30 parsecs distant is found to be broadcasting intelligent radio signals, then their news is already approximat

IrinaK [193]

Answer:

97.85 years, approximately.

Explanation:

Light travels at a constant speed of 186,000 mi/seg or 300,000km/seg accross the Universe (in vacuum conditions). Radio waves are also part of the electromagnetic spectrum, and they also travel at the same speed as Light does.

A light-year is a measure of the distance that Light travels during a year, that is, 5.88 trillion miles. Light travels the same distance per year because its speed is constant, and this is an excellent property that scientists take advantage to measure distances.

A parsec is 3.26 light-years (19 trillion miles), and (a very important datum to solve this question) one light-year is 0.306601 parsec, that is, in a year Light travels 0.306601 parsec at a constant speed. The same would happen with intelligent radio signals broadcasted from a distant star system.

So, considering all these facts, it is a matter of proportions to solve this question (mostly because speed of Light is constant):

$\frac{1 year}{0.306601 parsec} = \frac{X years}{30 parsecs}$

$x =\frac{1 year * 30 parsec}{0.306601 parsec}$

$x = \frac{30}{0.306601} years$

x = 97.84704 years or,

x = 97.85 years, approximately.

In other words, Light spends 97.85 years (terrestials) to travel 30 parsecs.

Likewise, radio waves travel at the same speed, so they spend the same years (97.85 years) travelling across the Universe to be finally detected by a radiotelescope located, for instance, here, in our planet.

Finally, the star system broadcasted intelligent radio signal with 'news' that are already approximately 97.85 years old'.
