Answer:
The number of bright-dark fringe is 42
Solution:
As per the question:
Wavelength of light, 
Length of the glass cell, x = 3.73 cm = 0.0373 m
Refractive index, 
Now,
To calculate the bright-dark fringe shifts, we use the formula given below:

Now, substituting the appropriate values in the above formula:

≈ 42
Answer:
Engineering aims to allow technical parts, structures and/or systems, such as those of a machine, to fulfill their function. To this end, occurring and/or desired processes (the operation thereof) are investigated and elaborated. Appropriate parts are designed individually or in a team, occurring stresses are calculated and the parts to be produced are modeled and/or specified on technical drawings. In some fields, maintenance is a standard part of the work to be performed. For a large part of engineering, standards and agreements have been drawn up with a view to the desired safety and practical applicability.
Answer:
ESTABLISHED
Explanation:
What is TCP?
A Transmission Control Protocol (TCP) is a communication protocol which allows the exchange of data between computers in a network.
When a Transmission Control Protocol connection is up and running meaning that both sides can send and receive data then the corresponding TCP socket states is known as "ESTABLISHED".
The most common socket states are:
LISTEN:
Before a TCP connection is made, there needs to be a server with a listener that will listen on incoming connection request.
ESTABLISHED:
When a TCP connection is up and running meaning that both sides can send and receive data.
CLOSED:
The CLOSED state means that there is no TCP connection.
There are a total of 11 TCP socket states:
1. LISTEN
2. SYN-SENT
3. SYN-RECEIVED
4. ESTABLISHED
5. FIN-WAIT-1
6. FIN-WAIT-2
7. CLOSE-WAIT
8. CLOSING
9. LAST-ACK
10. TIME-WAIT
11. CLOSED
