Answer: b. actuator
Explanation:
We know that a RW head ( or also known as read/write head) is a component of device which is usually appeared on the hard drive which is used to read and write data by the hard drive's disk . When data required to be read or write, the read/write arm is regulated by actuator.
[An actuator is a part of a device that is mainly responsible for moving and controlling a mechanism or system.]
Hence, All the read/write heads a hard disk are controlled by an actuator .
Answer:
A right triangle can have sides that are all integers. A set of three integer values for the sides of a right triangle is called a Pythagorean triple. These three sides must satisfy the relationship that the sum of the squares of two of the sides is equal to the square of the hypotenuse.

Answer:
While loop
Explanation:
It should be noted that the number of times which the computer will ask the user to take a guess is not known.
When we have a condition like this, the while loop (or in some programs; the do-while loop) is to be used.
To further back my point, see the following program in python.
<em>secret_code = 1234</em>
<em>user_guess = int(input("Take a guess: "))</em>
<em>while user_guess != secret_code:</em>
<em> user_guess = int(input("guess again: "))</em>
<em>print("You guessed right")</em>
<em />
The above program will keep asking the user to take a guess until the user enters 1234.
<em>This may or may not be possible with a for loop.</em>
This question is a bit ambiguous. However, this is what I found.
This question is related to Egress and Ingress. The answer in this case is
Egress.
Basically, Egress is another name for exit and is used in
very many situations to mean leave. Thus, in this example, Egress may mean flow
of fans out of a stadium. Typically, it is an opening or a path for an exit. On
the other hand, Ingress means flow of fans into the stadium and the roads that lead to the stadium.
