after one half life ___ % of the atoms will change to a stable isotope and % will remain radioactive. After three half lives ___% of the atoms will change to a stable isotope and ___% will remain radioactive.

does anyone know or what?

ya te mando la respuesta

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
