Please, what is a dense medium??

Dense medium, also referred to as “heavy liquid” is made up from the mixture of water and very fine and dense powder.

Explanation:

I know this cuz i took some hard physics.

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
