Your company resides in an area with rapid growth in both the corporate and residential areas surrounding your office. As such, your company has been experiencing several brownouts due to power grid problems (too much demand and not enough electricity). Fearing that your computers (especially the servers) could be damaged by these brownouts, your manager has asked you to find a solution to this problem.
Which of the following would be the BEST device to recommend to your manager for computer protection?
A. Surge suppressor
B. Power strips
C. UPS
D. Wall Outlet

Answers

Answer:

The correct answer is option C (UPS).

Explanation:

Since brownouts are reduced voltages that might not be good enough for the required electricity capacity for your company, fearing that your computers (especially the servers) could be damaged, it is best to use UPS for your computer protection.

A UPS also called (Uninterruptable Power Supply) can function as a Surge suppressor when the voltages entering your company might be higher than normal, it can also function too in protecting your computers (especially the servers) in the case of a brownout when voltage required by your computers dropped below the required level. In the case of a brownout, the  UPS supplies energy stored in its batteries to make the computers keep working without going off from lack of electricity.

Assume there are two variables, k and m, each already associated with a positive integer value and further assume that k's value is smaller than m's. Write the code necessary to compute the number of perfect squares between k and m. (A perfect square is an integer like 9, 16, 25, 36 that is equal to the square of another integer (in this case 3*3, 4*4, 5*5, 6*6 respectively).) Associate the number you compute with the variable q. For example, if k and m had the values 10 and 40 respectively, you would assign 3 to q because between 10 and 40 there are these perfect squares: 16, 25, and 36,.

Answers

Answer:

The program in Python is as follows:

#1

for i in range(10):

   print("MrRoyal",end=" ")

print()    

#2

for i in range(1,50,2):

   print(i,end=" ")

print()

#3

for i in range(0,101,5):

   print(i,end=" ")

print()

#4

i = 1

while i <=10:

   print(i,end =" ")

   i+=1

#5

myfile = open("People.txt", "r")

eachLine = myfile.readline()

while eachLine:

   print(eachLine)

   eachLine = myfile.readline()

myfile.close()

Explanation:

The program in Python is as follows:

Program #1

This iterates from 1 to 10

for i in range(10):

This prints the name for each iteration [modify to your name]

   print("MrRoyal",end=" ")

This prints a new line

print()    

Program #2

This iterates from 1 to 49 with an increment of 2

for i in range(1,50,2):

This prints the odd numbers in the above range

   print(i,end=" ")

This prints a new line

print()

Program #3

This iterates from 0 to 100 with a step of 5

for i in range(0,101,5):

This prints every 5th number

   print(i,end=" ")

Print a new line

print()

Program #4

This initializes the number to 1

i = 1

This opens the file in an append mode

f = open("myfile.txt", "a")

This loop is repeated from 1 to 10

while i <=10:

This writes each number to the file

   f.write(str(i))

Increment the number by 1

   i+=1

Close the file

f.close()

Program #5

This opens the file in a read mode

myfile = open("People.txt", "r")

This reads each line

eachLine = myfile.readline()

This loop is repeated for every line

while eachLine:

Print the content on the line

   print(eachLine)

Read another line

   eachLine = myfile.readline()

Close the file

myfile.close()

Answers

300! Is the answer for this problem. 450 is the bigger sum, and that’s the 3 part of the ratio. So when we divide 450 by 3 it gives us 150. 150 is what one point on the ratio stands for. We’re looking for what 2 points on the ratio is, so 150*2 which gives us 300 … hope this helps

The reasons to use simulation software in this context are I, II, and III. The correct option is D.

What is simulation software?

The process of simulating a genuine phenomenon with a set of mathematical formulas is the foundation of simulation software. It is essentially a program that allows the user to simulate an operation and view it without really conducting it.

Simulation is a decision-making and decision-support tool. You can use simulation software to assess, compare, and optimize different designs, programs, and policies. As such, it can be used to explain and defend decisions to multiple stakeholders.

By allowing the corporation to evaluate concepts early in the process before prototype automobiles are constructed, simulation software can save the company money.

Therefore, the correct option is D, I, II, and III.

If an if- else statement is true, it will include which kinds of results?

Answers

In an if...else statement, if the code in the parenthesis of the if statement is true, the code inside its brackets is executed. But if the statement inside the parenthesis is false, all the code within the else statement's brackets is executed instead.

Of course, the example above isn't very useful in this case because true always evaluates to true. Here's another that's a bit more practical:

#include <stdio.h>

int main(void) {

int n = 2;

if(n == 3) { // comparing n with 3 printf("Statement is True!\n");

}

else { // if the first condition is not true, come to this block of code

printf("Statement is False!\n"); } return 0;

}

Output:

Statement is False!
