What is a simple definition for electricity?

1 answer:

5 0

The movement of electrical power or charge is known as electricity. It is a secondary energy source, meaning that we obtain it through the conversion of main energy sources like coal, natural gas, oil, nuclear power, and other natural sources.

Electricity is made up of the incredibly tiny particles protons and electrons. Additionally, it might be used to describe the energy you experience as electrons migrate from one place to another. An example of electricity in nature is lightning strikes. A large number of electrons travelling through the air at once and releasing a lot of energy is all that lightning is. In addition, scientists now understand how to make or produce electricity. Because electricity can be regulated and transmitted across wires, this is advantageous. Following that, it can run computers, heaters, and lightbulbs. In the modern world, electricity now provides the majority of the energy required to run everything.

The answer would be A because grit means to fight hard to get what you want. Submission would be to give in to pressure and give up. Self-importance would be to only focus on yourself and no one else. A short attention span would not work out for you because you get distracted easily.

General Hardware Products Your boss, the IT director, wants you to explain FDDs, BPM, DFDs, and UML to a group of company manage

Bas_tet [7]

Answer:

1. FDD is a process and Analysts can use a FDD to create and use business functions and processes. It Requirements models are used when gathering requirements for a new system.

2. BPM is used on an ongoing basis for business process improvement. It is meant to improve order, insight and efficiency of the collective workflows that make up any given business process. BPM is meant to reduce any chaos within those collective workflows that make up a process and eliminate ad hoc workflow management. BPM means Business Process Management.

3. DFDs stands for Data Flow Diagram which will help software developers and designers to understand how they can take their next step to fit into the overall business process. DFDs paly key role for a successful requirements modeling.

4. UML can be used for modeling a system independent of a platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. UML gives a standard way to write a system model, covering conceptual ideas.

Explanation:

Functional decomposition diagram (FDD) is used to identify functions and define their structure. It is a technique to decompose the complex problem into manageable pieces or individual elements to develop the application or product.

DFDs: It contains a process (shape) that represents the system to model, in this case, the "Food Ordering System". It also shows the participants who will interact with the system, called the external entities. In this example, Supplier, Kitchen, Manager and Customer are the entities who will interact with the system.

Unified Modeling Language (UML): Edraw UML Diagram is the application of choice for many software engineers and designers. The software is fully compatible with 64 and 32-bit Windows platforms from Windows XP to Windows 10.

What is the result of the following code fragment?

anastassius [24]

Answer:

Explanation:

I don't know the language, but it is clear what is going on.

It looks like you are defining a value for a in both commands.

a.multiply(b); looks like you take the value in a (which is 10) multiply it by 25 and put the result back in a. So so far we have 10 * 25 = 250

Note the next command

a.add(b)

looks like you take the current value in a(which is now 250)

and put the value of b (which has not been changed. It is still 25) and put that in a (which is 250).

The result is 250 + 25 = 275

The answer is D. Since I only understand the logic, if this answer is wrong, I wish you'd leave a note.

Using selection sort, how many times longer will sorting a list of 40 elements take compared to a list of 5 elements

Hoochie [10]

It will take 8 times more time to sort a 40-element list compared to the time spent on a 5-element list.

We can arrive at this answer as follows:

We can see that if we divide a group of 40 elements into groups containing 5 elements, we will have 8 groups.
In this case, the time it would take to sort the list of one group of 5 elements would be repeated 8 times so that we could sort all the groups and their elements.

Another way to do this is to divide the number 40 by 5. We would have the number 8 as a result, which indicates that we would need 8 times more time to sort a list of 40 elements, compared to a list of 5 elements.
