Q:Why is it that any square additive identity matrix (which is.?) must have the property that any product of it with another matrix of appropriate dimension is the additive identity?Why can the additive identity matrices not have multiplicative inverses?

The additive identity matrix is composed entirely of zeroes. Therefore its determinant is 0 and it is non-invertible. It is also an annihilator under multiplication, which is another reason it is non-invertible.

Q:If I accidently put and oil leak additive in my gas what will happen?

It should be okay. Oil stop-leaks work by softening and swelling the rubbery seals rather than by gumming things up, and in a tank of gas the petroleum products for that will be just another additive - a weird one but not likely a problem. If you are asking about something not yet done it is better not to do it.

Q:provide your social security number and your information and the company is based from the U.K. where all the scams come from .are the company‘s claims true or is it just hype basically a mechanic in a bottle

I guess the best thing to do is to report them to the police. Edited Comment: I can't reply to your email because your email address is unconfirmed. It does appear that I somehow missed the point. I would think it unlikely that any fuel additive would be a cost effective (and safe for your engine) method of increasing mpg. Oil companies spend a lot of money researching and providing optimal gasoline. As for providing your social security number (unless you are getting for a job with them) this rings of attempted identity fraud which is why I made my comment about the police. Further comment: I see on Internet that the 4 E Corporation has many entries and they make far reaching claims about their product Ethos. There does not seem to be independent evaluations though (at least that I have been able to find)

Q:What is the definition of processed food exactly? How can a food be processed but not contain any additives?

Food that has gone through some kind of process - drying, cooking, freezing, pickling etc. Lots of processes don't involve addtives.

Q:Chicken powder is not a food additive

Monosodium glutamate and chicken powder, one is only a single amino acid glutamate spices, one is extracted from the chicken with a variety of amino acid condiments, both of which can generally be assured to eat. But the need to grasp the principle is not to eat too much, because everyone in the enjoyment of delicious at the same time, can not ignore the health of the market there is the implementation of the standard "salty food flavor" standard chicken powder, the provisions of the use of processed food The total weight of 0.1-0.4%, but most of the provisions of the amount or a teaspoon spoon and other vague argument.

Q:What situation are food additives justified?

I'll assume you mean artificial additives. I can think of no justification for these. All artificial additives try to simulate or replace something natural.Always use natural. In the domestic kitchen there can be no reason for introducing artificial foodstuffs. Anything you want to color or preserve can be done naturally(natural additives) as has been done for centuries before food was produced in factories. .

Q:Please tell me what is a pre-amp and what does it do better? What is the additive effect?

There is no additive effect for line level sources. In the case of a phono (turntable) signal, the pre-amp brings the signal to line level returns the RIAA equalization required in the vinyl mastering process to a normal curve. In audiophile circles, pre-amps are separate pieces from power amps.A pre-amp's main job is to take signals from sources and route them to the power amp for transmission to the speakers. An integrated amp is a pre-amp power amp on the same chassis. By the same token, a receiver is an integrated amp that adds a tuner.

Q:I generally change my oil pretty regularly, but last time I went a little too long and my oil volume was low. Pressure always looked good.

buy 10-40 grade fully synthetic .you cant go wrong .STP?scientifically treated petroleum .the first form of synthetic oils

Q:Hi, has anyone used Lucas oil stabilizer in there car or truck? If so what for and what differences did you hear/feel? Thanx

James is right. My little brother had one. Next to a harley it was the biggest POS I ever threw a leg over. A big heavy 750 with the power of a 250. If you don't have the physical dexterity and confidence to shift gearslike my brother, motorcycles are probably not for you.
