Splicing is the joining of two or more electrical conductors by mechanically twisting the conductors together or by using a special splicing device.

Which is an electrical conductor?

An electrical current flows through a conductor because it provides little to no resistance to the movement of electrons. Typically, good electrical conductors include metals, metal alloys, electrolytes, and even some nonmetals like graphite and liquids like water.

What is the purpose of a splice?

It can be used to package and stop the fraying of rope ends as well as as a foundation for more complex knots like the surgeon's knot and the square knot. Wrap the rope end around the standing part to form a loop, then bring the end of the loop through and draw the rope taut to tie an overhand knot.

Is it safe to splice electrical wire?

The splice may overheat and pose a fire risk when the current passes through it. Always utilize a junction box to store all the spliced wires while splicing wires. Any sparks produced during a short circuit are contained in junction boxes, which offer protection from electrocution and fires.

Determine whether or not the following pairs of predicates are unifiable. If they are, give the most-general unifier and show th
Evgen [1.6K]

Answer:

a) P(B,A,B), P(x,y,z)

=> P(B,A,B) , P(B,A,B}  

Hence, most general unifier = {x/B , y/A , z/B }.

b. P(x,x), Q(A,A)  

No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q.

c. Older(Father(y),y), Older(Father(x),John)

Thus , mgu ={ y/x , x/John }.

d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))

=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))  

This is not unifiable as x cannot be bound for both A and B.

e) P(f(x), x, g(x)), P(f(y), A, z)    

=> P(f(A), A, g(A)), P(f(A), A, g(A))  

Thus , mgu = {x/y, z/y , y/A }.

Explanation:  

Unification: Any substitution that makes two expressions equal is called a unifier.  

a) P(B,A,B), P(x,y,z)  

Use { x/B}  

=> P(B,A,B) , P(B,y,z)  

Now use {y/A}  

=> P(B,A,B) , P(B,A,z)  

Now, use {z/B}  

=> P(B,A,B) , P(B,A,B}  

Hence, most general unifier = {x/B , y/A , z/B }  

b. P(x,x), Q(A,A)  

No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q  

c. Older(Father(y),y), Older(Father(x),John)  

Use {y/x}  

=> Older(Father(x),x), Older(Father(x),John)  

Now use { x/John }  

=> Older(Father(John), John), Older(Father(John), John)  

Thus , mgu ={ y/x , x/John }  

d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))  

Use { y/x }  

=> Q(G(x,z),G(z,x)), Q(G(x,x),G(A,B))

Use {z/x}  

=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))  

This is not unifiable as x cannot be bound for both A and B  

e) P(f(x), x, g(x)), P(f(y), A, z)  

Use {x/y}  

=> P(f(y), y, g(y)), P(f(y), A, z)  

Now use {z/g(y)}  

P(f(y), y, g(y)), P(f(y), A, g(y))  

Now use {y/A}  

=> P(f(A), A, g(A)), P(f(A), A, g(A))  

Thus , mgu = {x/y, z/y , y/A }.

Liula [17]

A program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day is given below:

input_month = input()

input_day = int(input())

months= ('January', 'February','March', 'April' , 'May' , 'June' , 'July' , 'August' , 'September' , "October" , "November" , "December")

if not(input_month in months):

  print("Invalid")

elif input_month == 'March':

   if not(1<=input_day<=31):

       print ("Invalid")

   elif input_day<=19:

       print("Winter")

   else:

      print ("Spring")

elif input_month == 'April' :

   if not(1<=input_day<=30):

       print("Invalid")

   else:

      print("Spring")

elif input_month == 'May':

Why would students most likely need to collect data? Check all that apply
n200080 [17]
Well I would think all of them in some way. For the first one, students need to collect data (whether it’s mathematical, scientific, etc.) to answer a question. For the second one, they may need to know how much money is in there bank account or they may need to calculate a sale to order the item. For the third one, they may need statistical data to support a position. For the last one, a student could use technological data to be able to solve their problem sorting documents.
