Q:When the two additive colors blue (475 nm) and green (510 nm) are incident in equal magnitudes upon a white screen, the subtractive color cyan results. Consider two beams, one blue and one green. The blue beam is shined through a double-slit diffraction grating with slit distance of 0.0400 mm and then displays an interference pattern on a screen 1.00m away. If the green beam is then shined from the same position as the blue beam, what size diffraction grating would be required for the green beam so only a cyan interference pattern would be seen on the screen?

B, This first part contradicts itself (additive colors b g .subtractive color cyan) Light beams will be additive only. Interesting light problem, but I'm not going to attempt to answer the size except to say that it seems to be a factor that is clearly related to the ratio of the two wavelengths. Good luck.

Q:I guess this has more to do with the fact that Q is the additive group of rational numbers. In case the question above is too vague, I‘m not sure why every proper subgroup of Q is properly contained in another proper subgroup of Q.

Q:I have a transmission leak and cant afford to have it repaired.

i'm in the business i recommend none of them i've seen what they do to the inside of the trans get a shop to look at the leak it might be cheaper to fix then add the additive that will ruin the trans and pay for a rebuilt later

Q:What exactly is usually in tap water?

ive had too much experience with them.DONT use them.they damage the pumps and the injectors.unless you have a **** load of money in the bank DONT use them.

Q:A business in the production of food (instant noodles a bag of 35 grams) process, the illegal addition of sodium cyclamate and sorbic acid, in accordance with national GB2760 food additives use of health standards, in this food can not add these two things, the enterprise illegal What penalties may be taken and which department will be punished? Thank you, help out to help!

The number of specific fines as the case may be (you check food safety law), by the Quality Supervision Bureau of punishment, food production and processing are subject to the Quality Supervision Bureau to check, law enforcement. Food circulation is the responsibility of the Trade and Industry Bureau, catering services by the Food and Drug Administration.

Q:My co% is almost double. But I filled half a tank and used cleaning fuel additive, and took test only after 1/4 tank. Do you think testing with the additive still in caused high co readings??here are readingsHC 1.7 limit 4.0 passCO 79.9 limit 40.0 failNOx 0.06 limit 6.0 pass‘86 mazda b2000

I doubt it is the additive - I bet your O2 sensor is the original and it was useless ten years ago. O2 sensors degrade after about 100K miles (Bosch says after 60K miles, but they like to sell them) and that is the most important factor in CO emissions. If that doesn't do it you are probably looking at a replacement catalytic converter.

Q:The regular standard cheap honey in a jar you can buy in your local supermarket? Is that just actual honey or does it contain additives etc? Thanks.

>There are no additives added to any honey I know of. First of all, there is so much sugar in the honey that there wouldn't be any water available to dissolve chemicals into and the only thing that is really done to honey is to pasteurize it (heat treat it). Most bugs will not grow in high solids like that due to osmotic pressure, the rest are killed by pasteurization and that means no additives are needed.

Q:what is additive and subtractive colors?

Additive and subtractive colors has to do with color perception. Pigments (coloring in objects) reflect the color that you perceive. So for example a red square appears red because it predominantly reflects red light. If you took that pigment and mixed it with a blue pigment you get purple, if you add green pigment to that you would get a dark grey. Pigments are subtractive colors. But with light, if you take red light and blue light and combine them you get magenta light, and its brighter than either individual beam because you have twice the amount of light. If you were to add green light to that, you'd get white light and again it would be a brighter beam. Light is additive.

Q:I need it for my venus fly traps!!!!

East way: just buy perlite alone, or at least, not a Scott's Miracle-Gro product, or any soil mix that does NOT have added fertilizer. Harder way. Soak and rinse the perlite several times, allowing to dry out between rinsing.

Q:are you going to recommend using these products?

Today’s petroleum fuel refiners, marketers and Fatty Acid Methyl Ester (FAME) producers are operating in an era of striking changes and tighter margins. Environmental legislation to reduce emissions and improve fuel economy is having a great impact on fuel formulations and engine system design. Infineum delivers a wide range of fuel additives that enhance existing fuel properties (such as cold flow and lubricity) and bring unique performance features to enable fuel marketers to differentiate their products. Through research and development we are continually improving our additives to meet new environmental and business challenges.
