Answer:
It all depends on what you are prepared to spend and what sort of system you install. I have both grid tie and stand alone systems installed at my home, and both work really well, although we initially had some inverter problems with the grid tie system until we decided to only use top shelf gear.
We have 6.6 kW grid tie system on the roof of the house which supplies around 3 times our requirements, and a 1.5 kW stand alone system that supplies the backyard workshop and pool pump. The grid tie system cost around $6500 to install, and the small stand alone system cost $4500 although this was designed and built by myself, so a purchased system may well be more (batteries are still expensive, but this price is coming down).
In the current configuration (top tier panels, Fronius grid tie inverter and Victron stand alone inverter and charge regulator), we have had no failures in several years, and power bills are something that happen to other people.
My advice is look at what your requirements are, then double that when you spec out your system and don’t go for the cheapest price. Buy your components based on the quality and reputation of the manufacturer, it will be expensive, but you will save money in the long run. A good manufacturer will guarantee their products for at least 12 years and you should expect to get at least 20 years of life out of them.
Explanation:
Solar energy is more than enough for any business or home, but if you want to know if it is cost effective, you need to run the numbers. It does have to be grid-tied though to provide electricity at night or when cloudy for multiple days. In most cases, batteries are not cost-effective at this time.

Are DoS and DDos tactics appropriate for legitimate organizations to use against others? What fallout is considered appropriate fallout should an attack be used on others? Explain your answer.
Answer:
They are inappropriate
fallouts: Access denial and data theft
Explanation:
Dos ( denial of service ) and DDos ( distributed denial of service ) are inappropriate for legitimate organizations to use against each other. because DOS or DDos attacks are attacks on the server of an organization by sending an unusual amount of traffic to the server, thereby denying the devices and users connected to the server access to the server.

It's usually easier to change the design of a photo album slide show A.after you've created the presentation. B.before you've created the presentation. C.before you've planned out the presentation. D.after you've planned out the presentation but before creating it.
Answer:
A. after you've created the presentation.
Explanation:
A power point presentation is defined as a presentation program where one can create any presentation or design any layout like the photo album slide show to present it to others.
Once the album is created in the PowerPoint, it can be changed by going to the slide show and editing the content of the photo album of the slide show. Thus it is easier to make any changes in the design of the photo album slide show after the presentation have been created.
All of the following items may be sent via email EXCEPT *
1 point
soft copy attachments
hard copy attachments
web links
web pages
Answer:
hard copy attachments
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.
One of the most widely used communication channel or medium around the world is an e-mail (electronic mail).
An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send and receive texts and multimedia messages over the internet.
The following documents or files such as soft copy attachments, web links and web pages may be sent from one user to another through the use of an email.
However, hard copy attachments cannot be sent via email because they're physical documents and as such requires that they be delivered physically to the recipient.
In conclusion, you can only send soft copy documents that you cannot feel or touch with your hands over the internet and via email. Thus, an email is only designed to accept soft copy documents or files (attachments) but certainly not hard copy documents (attachments) in our technological era.

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=" ")

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()

Explanation:
In cell K2 enter a formula using the IF and OR functions, as well as structured references, to determine if Adam Moriarty can be a group leader. a. The IF function should first determine if the staff member’s Service Years is greater than 3 OR if the staff member’s college graduate status is "Yes". Remember to use a structured reference to the Service Years and the College Graduate columns.
Solution :
The value of the K2 cell is filled by IF and OR functions with structured references as :
[tex]K2=IF(OR([CBF\ \text{Staff[ Service years]} > 3, \text{CBF Staff[College graduate]}="Yes"),"Yes","No")[/tex]
Now if the syntax of the formula is not provided, then we can use :
[tex]$K2=IF(OR([[\text{Service Years}]]>3,[[\text{College Graduate}]]="Yes"),"Yes","No")$[/tex]
The staff member are required to satisfy one of the two or both the conditions so as to become a group leader. The conditions are :
--- staff member should served for more than 3 years
--- staff members should be college graduate
rem wap a programe using function procedure to calculate simple interest
Answer:
The program in Python is as follows:
def interest(P,R,T):
[tex]I = P * R * T/100[/tex]
return I
P = float(input("Principal: "))
R = float(input("Rate (%): "))
T = float(input("Time (years): "))
print(interest(P,R,T))
Explanation:
Required
Simple interest program using function
This defines the function
def interest(P,R,T):
This calculates the simple interest
[tex]I = P * R * T/100[/tex]
This returns the calculated interest
return I
The main begins here
These get inputs for principal, rate and time
P = float(input("Principal: "))
R = float(input("Rate (%): "))
T = float(input("Time (years): "))
This calls the interest function
print(interest(P,R,T))
