So I've tried this: v3(ehv'/kt)-1= 1.3 (ehv/kt-1) v'3 where as the ' notes the other wavelength..Also how do i turn the nm into frequency?

Homework Statement What is the temperature of a star if the flux at 450 nm is measured to be 1.3 times the flux at 650 nm Homework Equations To determine monochromatic flux I use: 2πhv3/c2 ex-1 x= hv/kT The Attempt at a Solution So basically I plug in the...

With my previous method before your help, I came to about 1.7g per second needed. That seem reasonable?

So I took E=mc^2 and i plugged in: (0.2916 amu x 1.66053 x10^-27 ) to convert amu to Kg then that by c^2 which is 9x10^16 m/s and got 4.358x10^-12 is that joules released by combining 4H to 1 he?

haha just so happen to be reading that as you posted..

Homework Statement Suppose we succeed in building a H-->He fusion reactor. How much hydrogen would have to be converted per second to supply the world's electricity consumption of 10^13kwh. Homework Equations This is what I am looking for, I think i can figure it out once I know the...

Apologies for not getting back sooner, I had the wrong email attached to this account. Thanks for the response, I feel silly on some of my oversights such as e (need to look on my calculator more).
