Ahydrogen atom has a diameter of about 10 nm.
a. express this diameter in meters.
b. express this diameter in millimeters.
c. express this diameter in micrometers.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

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
