Answer:

Answered

Explanation:

function from S_1 to S_2 (functions have unique mapping

each element in S_1 has 2 elements to map to in S_2 and there are 3 elements in S_1

therefore number of functions = 2^3 = 8 (2 choices for each of 3 elements)

a) relations between S_1 and S_2 are subset of S_1 x S_2

there are 6 elements in S_1 x S_2 therefore relations would be 2^6 = 64

(no of subsets of set of n elements = 2^n)

b) By above explanation functions from S_2 to S_1 = 3^2 = 9

 and relation from S_2 to S_2 = 2^4 = 16

A Java main method uses the parameter (String[ ] variable) so that a user can run the program and supply "command-line" paramete
Firdavs [7]

Answer:

The answer is "Option a"

Explanation:

  • In java, the main function is the point of entry of every java program. Its syntax always starts "public static void main" with (String args[]), in which it can also be modified by the name of the string array name.
  • It also known as an entry point is the key process. In any program, it is the first method, that executes whenever you run a program. There is one main feature in a regular app that uses instances of certain classes to operate.

Define and implement a method that takes a string array as a parameter and returns the length of the shortest and the longest st
Drupady [299]

Answer:

#HERE IS CODE IN PYTHON

#function to find length of shortest and longest string in the array

def fun(list2):

   #find length of shortest string

   mn=len(min(list2))

   #find length of longest string

   mx=len(max(list2))

   #return both the value

   return mn,mx

#array of strings

list2 = ['Ford', 'Volvo', 'BMW', 'MARUTI','TATA']

# call the function

mn,mx=fun(list2)

#print the result

print("shortest length is:",mn)

print("longest length is:",mx)

Explanation:

Create an array of strings.Call the function fun() with array as parameter. Here min() function will find the minimum string among all the strings of array and then len() function will find its length and assign to "mn". Similarly max() will find the largest string and then len() will find its length and assign to "mx". Function fun() will return "mn" & "mx".Then print the length of shortest and longest string.

Output:

shortest length is: 3

longest length is: 5

Because of the abundance of water on planet Earth, hydrogen gas (H2) is a candidate in the search for a replacement for petroleu
Dennis_Churaev [7]

The reason why plants are considered to be one step ahead in the utilization of hydrogen as an alternative fuel source is because; Plant cells possess water-splitting enzymes

<h3>What are splitting Enzymes?</h3>

Splitting Enzyme’s are like aldolases that catalyze the conversion of a molecule into two smaller molecules without the addition or removal of any atoms.

Now in plant biology, plants make use of he light-driven water-splitting/oxygen-evolving enzyme known as Photosystem II in photosynthesis to split water.

Vesnalui [34]

Answer:

6.025seconds

Explanation:

For each link we have,

Dtran = 10mbits/10mbps =1 second

Dprop = 5000km/2×10^8m/sec =0.025sec.

Total delay =( 5 + 2-1) + Dtran+ 2 Dprop= 6.025seconds
