Answer:

Assuming that all the necessary declarations are made and given statements are only an extract, we can conclude that the given piece of code contains error. 

Explanation:

Let us analyze each one in order.

count >0  This statement is right if we match this with the syntax of regular comparison operation. Here count is an operand, “0” is the constant operand and these two operands are operated by the operator “>”.

when we take total / count >0 Here count>0 returns Boolean and total is assumed to be an integer and an integer cannot be divided by a Boolean value. so it can be rectified as (total / count)>0.

A mass m is attached to the end of a rope of length r = 3 meters. The rope can only be whirled around at speeds of 1, 10, 20, or

gayaneshka [121]

Answer:

Explanation:

Let's do this in Python. We know that the formula for the centripetal force caused by whirling the mass is:

$F = m\frac{v^2}{r}$

where v is the speed (1, 10, 20, 40) and r = 3 m is the rope length.

Then we can use for loop to try calculating the tension force of each speed

def maximum_speed(m):

for speed in [1, 10, 20, 40]:

tension_force = m*speed^2/3

if tension_force > 60:

return speed

Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times

otez555 [7]

Answer:

The program written in python is as follows

def countchr(phrase, char):

count = 0

for i in range(len(phrase)):

if phrase[i] == char:

count = count + 1

return count

phrase = input("Enter a Phrase: ")

char = input("Enter a character: ")

print("Occurence: ",countchr(phrase,char))

Explanation:

To answer this question, I made use of function

This line defines function countchr

def countchr(phrase, char):

This line initializes count to 0

count = 0

This line iterates through each character of input phrase

for i in range(len(phrase)):

This line checks if current character equals input character

if phrase[i] == char:

The count variable is incremented, if the above condition is true

count = count + 1

The total number of occurrence is returned using this line

return count

The main method starts here; This line prompts user for phrase

phrase = input("Enter a Phrase: ")

This line prompts user for a character

char = input("Enter a character: ")

This line prints the number of occurrence of the input charcater in the input phrase

print("Occurence: ",countchr(phrase,char))

f. Apply encryption to VM files.

b. secure the VM files with permissions

Explanation:

Installing anti-malware is a must on each VM OS OR Host OS to protect both servers and hosted workstations.

Scheduling update OS patches and anti-malware and scanning server or host operation are also must.

Securing VM files as best practices better to encrypt and decrypt is the best method or best practices.

Even protected VM files sometimes can be hacked and damaged the VM files.

VM is a virtual machine technology is used in windows 10. Before login decrypts the VM and connects to virtual machines. On disconnected encrypted is safer.
