Answer:
Market place is the essence of "Buyers and Sellers" of the products that are available in the market.
Explanation:
Consumers/buyers are the persons that need something, but they cannot prepare it by themselves, and there are some people who produce some products or goods and want to sell the to earn some money.
To facilitate these both two, Market place is the place where people can buy or sell their products.
Answer:false
Explanation: why would you need a powerful it security system, if they already have authorized access?
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.
Answer:
this is the correct answer
