Vinil7 [7]3 years ago
3 0

Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.

A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Polyphase power systems were independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström, John Hopkinson and Nikola Tesla in the late 1880s.

StartTLS, delete.

Bind, modify.

Bind, add.

Answer:

StartTLS, delete

Explanation:

StartTLS is a computer networking term for email protocol command, in which a system administrator buses it to command an email server that an email client running in a web browser, wants to turn an existing insecure connection into a secure one. Thus, during this process, StartTLS permits a client to communicate securely using LDAPv3 over TLS.

On the other hand, the DELETE operation can make a change to a directory object.

What is the final amount stored in value if the computer selects 17 as the
nadya68 [22]

Answer: -17

Explanation:

Our random number is 17. Let's go through line by line.

  1. value is a random number picked which is 17
  2. valueB = 17 / 2 = 8.5
  3. If value is greater than 0 AND value has a remainder of 1, we will set the value to value* -1.
  4. Value is now 17 * -1 = -17

Let's quickly calculate value mod 2. 17 % 2 = is 1. If you're wondering how we did that, the remainder after dividing 8 into 17 twice is 1, because 17 - 16 = 1.

We stop after line 4 because we stop the conditional statement after one condition is filled.

Consider the following code snippet. Is count < 5 always true, always false, or sometimes true/sometimes false at point 2?
AleksAgata [21]

Answer:

c. count 5 is sometimes true/ sometimes false at point 2

Explanation:

The while-loop statement is a conditional looping statement in programming that executes a block of code if a condition is met.

In the program, the value of the count variable is first initialized to zero but the while-loop would continuously increment the count variable by one if the count variable is less than five, which means that the while-loop stops and the code block is not executed at count equal to five.
