Hi, I am having trouble with the last question in my assignment. It's on blackbody radiation and total power per area and whatnot. those questions i was able to do fine, however when i came to this problem i was a little lost..
here it goes, i'll type the whole thing out..
"The most important energy source in so called main sequence stars is fusion of four protons into He nuclei.
A star has a radius r
How many he nuclei does the star produce per second if He production is the dominant energy source?
Use the Q value for the conversion 4H ->He to estimate the amount of raditation energy generated by hydrogen burning, and assume that the radiation energy output per second corresponds to the energy generated by hydrogen burning in a second."
any help would be greatly appreciated. thanks
