• Type of atom H (Hydrogen)

H = 4

You dont understand? JUST SEE THE FORMULA C MEANS ONLY HAVE 1 CARBON ATOM AND H4 MEANS 4 ATOM OF HYDROGEN

Answer:

D = array('f',[2.5, 3, 7.4])

Explanation:

is the answer

A variable must be declared with an array type before the array itself can be created. Array types resemble other Java types, with the exception that square brackets are placed after them ( [] ). Thus, option D is correct.

Using the NumPy library, new data types known as arrays can be produced in Python. NumPy arrays are created for numerical studies and only contain one data type.To build an array, use the array() method after importing NumPy. The input for the array() function is a list.

An array, also known as a database system, is a group of things or data that is held in a contiguous memory area in coding and programming. Several instances of the same kind of data are grouped together in an array.

Therefore, D = array('f',2.5, 3, 7.4)  line of code would create an array.

Answer:

In Python:

Length = float(input("Length: "))

Width = float(input("Width: "))

Area = Length * Width

Perimeter = 2*(Length + Width)

print(Area)

print(Perimeter)

Explanation:

This gets the length from the user

Length = float(input("Length: "))

This gets the width from the user

Width = float(input("Width: "))

This calculates the area

Area = Length * Width

This calculates the perimeter

Perimeter = 2*(Length + Width)

This prints the area

print(Area)

This prints the perimeter

print(Perimeter)

Answer:

Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope in 1590.

Explanation:

A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Eeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.

Answer:

E. New technology is beneficial but can also be used in a detrimental way.

Explanation:

New technology such as cryptocurrency (powered by blockchain technology) can be regarded as a welcome development that has benefited the society in so many good ways. However, cryptocurrency as a new technology also has disadvantages it presents to the society. One of such negative influence cryptocurrency has is that it can be used for illicit activities such as money laundering, funding terrorism and so on.

So, in summary, we can conclude that:

"New technology is beneficial but can also be used in a detrimental way."

Answer:

#include <iostream>//header file

#include <string>//header file

using namespace std;

string integer_to_reverse_binary(int integer_value)//defining a method integer_to_reverse_binary  

{

   string ret = "";//defining string variable

   while (integer_value > 0) //using while loop to check integer_value value is greater than 0

   {

       ret += '0' + (integer_value % 2);//adding zeros in remainder value

       integer_value /= 2;//holding quotient value

   }

   return ret;//return string value

}

string reverse_string(string input_string)//defining a method reverse_string that holds a parameter user_String  

{

   string result;//defining a string variable  

   for (int i = 0; i < input_string.length(); ++i)//use for loop to calculate value  

   {

       result += input_string[input_string.length()-i-1];//add value in result variable

   }

   return result;//result result variable value

}

int main()//defining main method  

{

   int num;//defining integer variable

   string str;//defining string variable

   cin >> num;//input num value

   str = integer_to_reverse_binary(num);//use str variable to call the integer_to_reverse_binary method

   cout << reverse_string(str) << endl;//printing the reverse_string method value

   return 0;

}

Output:

Explanation:

In this code two string method "integer_to_reverse_binary and reverse_string" is defined that holds one parameter "integer_value and input_string".

In the first method a string variable is defined, that use the while loop to check integer value is greater than 0 and add zeros in the value and return its value as a string.

In the second it reverse the string value and store into the result variable, and in the main method the "num and str" variable is defined, and in the num it takes integer value and pass into the above method and print its return value.
