Answer:

The energy source that does not use heat in the process of converting it to electricity is;

c. Sunlight

Explanation:

In converting Sunlight energy source to electricity, the photons in the light from the Sun excite electrons in the solar cells silicon layers, such that the electrons travel from n-type silicon layer to the p-type silicon layer creating electric potential energy that does work as the electrons flow back in the form of electricity from the p-type to the n-type silicon layer through an external circuit

Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum

NemiM [27]

Answer:

The answer to this question as follows :

Structure definition:

struct Server //define structure server.

{

string manufacturer;

//define string variable.

string model, serialnum; //define string variable.

int year;

//define integer variable.

double clockSpeed;

//define double variable.

int cores; //define integer variable.

int ram;

//define integer variable.

int storage;

//define integer variable.

};

Explanation:

Structure is a collection of heterogeneous(different type) elements. It is a user-define datatype which is available on the C/C++ programming language. To define any structure we use the struct keyword. The syntax of defining structure can be given as:

Syntax:

struct structure name

{

//define variables

//statements and code.

};

struct structure name

{

//define variables

//statements and code.

}create structure variable;

In the above structure code, we define a structure that is "Server". In this structure, we define different types of variables that is " manufacturer, model, serialnum, year, clockSpeed, cores, ram, and storage". In this structure variable manufacturer, model and serialnum datatype are a string and clockSpeed datatype is double and variable year, cores, ram, and storage data type is an integer.

Following are the python program to the given question:

from collections import defaultdict #import package

import heapq as h#import package

def primsMST(gr, st_v): # defining a method primsMST that takes two values in parameters

primalMST = defaultdict(set)#defining primalMST as a variable that calls defaultdict method

v = set([st_v])# defining a variable v that calls the set method and hold its value

e_list = [(c, st_v, to)for to, c in gr[st_v].items()]#defining variable e_list that use loop to hold value in list

h.heapify(e_list)# use package that holds heapify and holds its value

while e_list:#defining while loop that checks e_list

c, s, e = h.heappop(e_list)#holding heapop method value in c,s,and e variable

if e not in v:#defining if block checks e value is not in v

v.add(e)# use add method to add value in v

primalMST[s].add(e)#use primalMST as list that adds value in mwthod

for nxt, c in gr[e].items():#defining for loop that uses nxt, and c variable that checks value in list

if nxt not in v:#defining nxt variable that checks value is not in v

h.heappush(e_list, (c, e, nxt))#add value into the heappush method

return primalMST#return method value

connects=[['A','B',1],['B','C',4],['B','D',6],['D','E',5],['C','E',1]]#defining a list connects

my_gr=dict()#defining a variable my_gr that holds method dict() value

for el in connects:#defining a for loop that uses el to count connects list value

my_gr[el[0]]=dict()#use my_gr as list hold value in dict method

my_gr[el[1]]=dict()#use my_gr as list hold value in dict method

for el in connects:#defining another for loop that uses el to count connects list

my_gr[el[0]].update({el[1]:el[2]}) # use update method that update value in my_gr

my_gr[el[1]].update({el[0]:el[2]})# use update method that update value in my_gr

x=dict(primsMST(my_gr, list(my_gr.keys())[0]))#defining x variable that calls dict method and hold its value

a=[]#defining an empty list

for k in x:#defining a for loop that uses k to hold dict method value

for no in x[k]:#defining a loop that checks list value

a.append([k,no,my_gr[k][no]])#use a that add value in list

print(a)#print list value.

Output:

Please find the attached file.

Program Explanation:

Import package.
defining a method primsMST that takes "gr and st_v" as parameters.
Inside the method, a primalMST as a variable is declared that calls "defaultdict" method.
Use the v variable that calls the set method and hold its value.
Defining "e_list" that uses the loop to hold value in lists, and define the heapify and holds its value.
In the next step, it defines a while loop checks e_list, and defines variable and hold value into the method and use another if to check value and return its value.
A list "connects" is declared that holds a value and defines a "my_gr" that holds "dict" method value and uses multiple for loop to print the calculated list value.
