Answer:
Heat transfer rate(Q)= 1.197kW
Power output(W)=68.803kW
Answer:
Q' = 8 KW.h
Q'=28800 KJ
Explanation:
Given that
Heat Q= 4 KW
time ,t = 2 hours
The amount of energy used in KWh given as
Q ' = Q x t
Q' = 4 x 2 KW.h
Q' = 8 KW.h
We know that
1 h = 60 min = 60 x 60 s = 3600 s
We know that W = 1 J/s
The amount of energy used in KJ given as
Q' = 8 x 3600 = 28800 KJ
Therefore
Q' = 8 KW.h
Q'=28800 KJ
Answer:
The code is given below in Python with appropriate comments
Explanation:
# convert list to set
male_names = set(['Oliver','Declan','Henry'])
# get remove and add name from user
remove_name = input("Enter remove name: ")
add_name = input("Enter add name: ")
# remove name from set
male_names.remove(remove_name)
# add new name ij set
male_names.add(add_name)
# sort the set
a = sorted(male_names)
# print the set
print(a)
Answer:
Backdoor
Explanation:
The back door fragment in a program allows user to access backdoor information without necessarily following the common security procedures needed. In this case, once the programmer keys in the username he or she logs in without putting password. Therefore, this is a backdoor fragment.
