2000 W with si prefix

Answers

In the SI prefix, the value of 2000 W is also written as 2 kW. This is because 1 kW = 1000 W.

What is meant by the SI prefix?

SI prefixes may be defined as a collection or sequence of prefixes to units in the International System of Units, or SI. These can denote very small or very large amounts.

These types of prefixes are most commonly utilized in computing to refer to storage space, such as bytes, even though storage is not an official SI unit.

The designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

Using at least one quote from the sermon, analyze the effectiveness of Edwards's message.(Think:Is he convincing?Why/why not?Would his message have the desired effect on a congregation?How about on you personally?Why/why not?Explain.)God has laid himself under no obligation, by any promise to keep any natural man out of hell one moment. God certainly has made no promises either of eternal life, or of any deliverance or preservation from eternal death, but what are contained in the covenant of grace, the promises that are given in Christ, in whom all the promises are yea and amen. But surely they have no interest in the promises of the covenant of grace who are not the children of the covenant, who do not believe in any of the promises, and have no interest in the Mediator of the covenant.So that, whatever some have imagined and pretended about promises made to natural men's earnest seeking and knocking, it is plain and manifest, that whatever pains a natural man takes in religion, whatever prayers he makes, till he believes in Christ, God is under no manner of obligation to keep him a moment from eternal destruction.So that, thus it is that natural men are held in the hand of God, over the pit of hell; they have deserved the fiery pit, and are already sentenced to it; and God is dreadfully provoked, his anger is as great towards them as to those that are actually suffering the executions of the fierceness of his wrath in hell, and they have done nothing in the least to appease or abate that anger, neither is God in the least bound by any promise to hold them up one moment; the devil is waiting for them, hell is gaping for them, the flames gather and flash about them, and would fain lay hold on them, and swallow them up; the fire pent up in their own hearts is struggling to break out: and they have no interest in any Mediator, there are no means within reach that can be any security to them. In short, they have no refuge, nothing to take hold of, all that preserves them every moment is the mere arbitrary will, and uncovenanted, unobliged forbearance of an incensed God.The use of this awful subject may be for awakening unconverted persons in this congregation. This that you have heard is the case of every one of you that are out of Christ. That world of misery, that lake of burning brimstone, is extended abroad under you. There is the dreadful pit of the glowing flames of the wrath of God; there is hell's wide gaping mouth open; and you have nothing to stand upon, nor any thing to take hold of, there is nothing between you and hell but the air; it is only the power and mere pleasure of God that holds you up.You probably are not sensible of this; you find you are kept out of hell, but do not see the hand of God in it; but look at other things, as the good state of your bodily constitution, your care of your own life, and the means you use for your own preservation. But indeed these things are nothing; if God should withdraw his band, they would avail no more to keep you from falling, than the thin air to hold up a person that is suspended in it.. . .How dreadful is the state of those that are daily and hourly in danger of this great wrath and infinite misery! But this is the dismal case of every soul in this congregation that has not been born again, however moral and strict, sober and religious they may otherwise be. Oh that you would consider it, whether you be young or old! There is reason to think, that there are many in this congregation now hearing this discourse, that will actually be the subjects of this very misery to all eternity. We know not who they are, or in what seats they sit, or what thoughts they now have. It may be they are now at ease, and hear all these things without much disturbance, and are now flattering themselves that they are not the persons: promising themselves that they shall escape. If we knew that there was one person, and but one, in the whole congregation, that was to be the subject of this misery, what an awful thing it would be to think of! If we knew who it was what an awful sight would it be to see such a person! How might all the rest of the congregation lift up a lamentable and bitter cry over him! But alas! Instead of one, how many is it likely will remember this discourse in hell! And it would be a wonder, if some that are now present should not be in hell in a very short time, before this year is out. And it would be no wonder if some persons, that now sit here in some seats of this meetinghouse in health, and quiet and secure, should be there before tomorrow morning.
