R₂ and R₃ can be replaced by:

The total R of the circuit is R₁+R₅+R₄ = 706 2/3
So the current in the circuit I=V/R is 100/(706 2/3) = 15/106 A
(I'm deliberately not trying to round the result)
The voltage drop over R₄ is V=I*R = 15/106 * 500 ≈ 70
So answer C would be my choice.
Answer:
Promotes innovation by advancing measurement standards
Explanation:
The National Institute of Standards and Technology was Founded in the year 1901, this agency is a non-regulatory body that is found within the United States Department of Commerce.
The mission of this agency is the promotion of innovation and also industrial competitiveness through the advancing of measurement science, standards, and also technology in several ways that raises economic security and also brings about improvement in the quality of life.
Answer: A. passive attacks
Explanation:
Passive attack is a type of attack where by a system is tracked and scanned to determine how vulnerable it is and to also detect open port. The major purpose of a passive attack on a network is to gain access to the information of the target without altering the data.
A passive attack on a network may not be necessarily malicious, it is a type of network attack that is very difficult to detect.
Methods of carrying out passive attacks.
•War driving: scanning of networks is carried out to detect Wi-Fi that are vulnerable.
•Dumpster driving: Attackers or intruders search for information from discarded computers and
other gadgets, those information can help to attack a network.
Answer:
Explanation:
I have written the code in Java. It contains the class Insertion Sorter which has the InsertionSort function. This function uses the insertion sort algorithm to sort a comparable array and if it fails to do so for whatever reason it throws an Illegal ArgumentException. If it sorts the array correctly it returns the number of changes that needed to be made in order to correctly sort the array. Due to technical difficulties I have attached the code as a text document below and proof of output in the picture below as well.
