Answer:
Both Technicians are correct.
Explanation:
Remember that Ohm's Law its a relationship between Voltage (E), Current (I) and Resistance (R) in an electrical circuit. This relationship is defined by the following equation:

Each one of the letters could be called a variable. Now, also remember that the number of equations you have is equal to the number of variables unknown you could have.
In Ohm's Law you have 3 variables (E,I,R) and 1 equation. It means that you need to know 2 variables (Whatever 2 variables) to know the third.
Technician A says, in other words, that could calculate the Circuit current flow (I) knowing total circuit resistance (R) and total voltage (E). Note that Technician A knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

Technician B says, in other words, that could determine the unknown resistance (R) knowing total current (I) and source voltage (E). Once again, note that Technician B knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

It is concluded that both technicians are right.

See explaination
Explanation:
2a)
A hacker group hacked into the Bay Area Rapid Transit system, this was done to protest BART’s shut down of wireless communication in some BART stations. Such attacks is done mostly to stand for some situation which happened previously. Hence, we can say it is a form a hacktivism. It was not ethical as it disrupted the system for some time.But this is also a form of protest which is been done by some group of peoples.
2b)
If a foreign government launches a hacking attack, it can be considered a war.
If this type of attack happens then the repercussions may result to the war.
2c)
We gave an analogy between merchants accepting some amount of shoplifting, on the one hand, and merchants and credit card companies accepting some amount of credit card fraud, on the other hand.
THe streght so called can be pointed out as the money is rolling in the market and the business keeps on going.
The weakness can be described as the loss which is being incurred by the company.
Answer:
The second is that laughter prepares us for tough conditions. And it does always ensure good things for us, and there are many real advantages of the laughter that we can trace out. And all those can be parsed from our real life. We just need to think of a sad situation and try to realize how laughter helps us get rid of that sad situation. And that is what is the central idea of the second section.
