much energy.....? If an X-ray detector measures 1 mW of power from an X-ray binary 2.5 kpc away, how much energy (in mW) would it measure from an equally bright x- ray binary 5 kpc away?
Can someone confirm if the way i solved this was correct and explain why or why not?
2.5kpc->5kpc is a multiple of 2 so 2.5/2=1.25/5=0.25 or did I just make up a random formula that happened to work.....? Which is what i believe atm.
AND now i feel like an idiot thank you below :O.
Although apparently what i did is the proof equivalent of the inverse square law XD.
For instance a 2.5 object and 7.5 object would be 2.5/7.5=0.333^2=0.111
my way would have it as 7.5/2.5=3-> (2.5/3)/7.5=0.111
=)
