ooo half life ... its been a while since i did these ... let me think
ok listen closely
assume that the isotope starts at x units
. after 1 week half will be gone, or x/2, after the second week half of what remains will be gone. x/2 /2 or x/4, after three weeks x/8 and after 4 weeks, x/16 or 1/16 of the starting amount
get it ?
yes i kinda already understood half life basically each weach this isotope will loose half of it total life left
btw i gotta ask ... is this for hig school ?
so W1=1/2 W4=1/16
so at 1 month it will have 1/16 of its life
thats what i think
ok thank you
half of the orignal in the first week ... half of the half left in the second week (quater of the orignal) and so on
get the sequence ?
and just to clarify on the last question we did i divided those numbers and got 60041537135.7 and i add KG-J
yes i got it thank you so much
just kg .... cause its just simple mass ... nothing more ..and btw ... do the math again just to be sure yu have the figures right ..
i was kinda hoping for a medal ...its like my first time here on open study ... and damn is this place cool
i literally divided the two as is
yeah yu did multiply it by C right ? the speed of light
yu did right ... as long as you multiplied C as well
no i divided m=e/c^2
yeah divide ...sorry my bad
its correct thrn
C must be in m/s
and what about the ^2 over c? is that encompassed in the number i used for the speed of light
yes .. thats the speed of light squared
well thank you than
no problem ... always happy to help ..
