Answer:

D. output derived from key K3

Explanation:

The cyphertext = EK3( DK2(EK1(plain text)))

And from the above, it is quite clear that in the case of the triple DES, the plain text is first encrypted using key 1, and then it is decrypted using the key 2. Finally, it is encrypted using the key 3, and this results in the final encrypted content, and which is the ciphertext. Thus, this clarifies that the output derived from the key k3 is the actual ciphertext, and hence the correct option for the above question is as mentioned above.

<h2>Answer:</h2>

<u>An inserted graphic in Excel is </u><u>B. inserted in the active cell.</u>

<h2>Explanation:</h2>

A graphic is considered as any picture or shape present in the directory of any computer. So when you are working in an Excel worksheet and you insert any graphic so it means you have inserted a shape. It may be a line, picture or any other geometrical shape, then this image or graphic will be inserted in the cell which is active at that time and no where else. Therefore option B is the correct answer.

Can someone explain to me how to do circuit calculations

GenaCL600 [577]

Use the following rules:

- The sum of currents that enter and exit a node (junction) is always zero. So if you have 3 wires that connect, through one flows 2A, the other 3A, then the third must deliver 5A (taking the direction into account!)

- The sum of voltages across different components should always add up. So if you have a battery of 10V with two unknown resistors, and over one of the resistors is 4V, you know the other one has the remaining 6V.

- With resistors, V=I*R must hold.

With these basic rules you should get a long way!
