Acid rain falling on a rock outcrop over a period of many years can cause the rock on the service to dissolve. this is an example
a. erosion
b. the rock cycle
c. chemical weathering
d. mechanical weathering

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
