Answer:
Check the explanation
Explanation:
All website around the world/internet is a collection of different web pages, HTML can be referred to as the single most essential standard when it comes to web design, as well as it being the only one that’s enormously required or needed if you plan to create a web page.
to answer the question above, we will be creating an HTML document that describes nested ordered lists of cars, kindly check the attached images below to see the written codes to solve the question.
Answer:
The following are the answer to the given points:
Explanation:
In point (a):
Calculating the long-distance call cost:

Calculating the local call cost:

Calculating the overall cost of PSTN:

In point (b):
Calculating the call rate per second and the average arrival rate:

The call average length:
The complete agent number:

The strength of traffic:
The occupancy of the agent:

Calculation of obtained:

We get = 0.329 to substitute values.
In point (c):
The rate of blocking = 
average call time 

In point (d):
Calculating the number of link, which is required:
In point (e):
Calculating the Line Number:
PSTN line number:

In point (f):
The gross design expense = $ 2309. 5
Answer:
subset([],[]).
subset([X|L],[X|S]) :-
subset(L,S).
subset(L, [_|S]) :-
subset(L,S).
Success:
subset([1,3], [1,2,3]).
subset(X, [1,3,4]). % error handling to compare sets in a given order
Fail:
subset([2,1], [1,2,3]). % compares in a different order from the first.
Explanation:
The function "Subset" in the source code above accepts two sets, then checks if the first set is a subset of the second. The code returns true if the condition is met.
1 and 4 are both true, Although it looks like 1. being your correct answer.
The correct answer is B, a laminated core and a shading coil.
A key difference in an AC relay is the presence of a "shading coil". The purpose of this coil is to keep the relay on when the current drops to zero during phase change (note that in AC power the current and voltage are alternating in a sine wave around 50/60 times per second). The shading coil retains some magnetic energy and essentially holds the relay ON when the current drops to zero momentarily due to the AC waveform.
AC relays also have a laminated core to prevent losses due to eddy current heating.
