a pwm signal is generated by pic micro. now i want to shift the signal by 120 degrees to become the second signal. what i meant is the first signal is started at 0 deg and the second one is started 120 deg later. the second signal is still have the same frequency and duty cycle as the first one. any circuits that can do the trick?

someone please help, it's urgent!!

Mendel crossed a wild-type (round, yellow peas) pea plant to a pure breeding wrinkled green pea plant. He got 55 round yellow, 51 round green, 49 wrinkled yellow and 53 wrinkled green. What was the genotype of the two parents. Use your own nomenclature.

You cross a Drosophila female with forked bristles (f) and black body (b) to a true breeding wild-type male. You get only wild type female and forked male progeny. There are no black progeny. Are forked and black on the same chromosome? Are they X-linked? Explain.

When making steel:

First Iron ore (iron oxide) carbon (coke charcoal, etc.) and limestone are mixed in a furnace and air is blow through The limestone is present to remove silicon but the carbon iron oxide and air blast work to generate a high enough temperature that the carbon can rob the iron oxide of its oxygen.

Second the iron in a melted state is subjected to more air flow (atmospheric oxygen to remove the carbon, thereby producing very low carbon iron.

Third, carbon is put back into the nearly pure iron to make high carbon steel.



This process could be summarized as:

· Carbon is used to remove oxygen

· Oxygen is used to remove carbon

· Carbon is added back in.



This seems contradictory! Explain the process and why a blast furnace is needed for the first step and a Bessemer converter might be used in the second case and why after getting all the carbon out the carbon is put back in. Place the development of this process in a a historical context.



Additional information might be found on the internet or in the accompanying booklet.



In reviewing the steel making process, consider that originally, charcoal from biological sources was used in steel making until it was discovered that coal mined from the ground could be turned into coke, and this would provide the carbon much more cheaply. IF we assume that manmade release of carbon dioxide is a significant factor in global warming, since so much carbon is burned in making steel, perhaps we could find a bio-based source so that we are simply recycling atmospheric carbon rather than increasing it. Could we afford to do this? Would we burn down the environment faster than it grows, Could we afford steel?

This question was asked;
"What is the greatest common factor of 60 and 100?" I don't understand some of the answers. Is it anything that divides into both 60 and 100 but has to be the highest possible factor divisible by both?
